WELDING PROCESSES

MIG-MAG
The process of continuous seam welding is widely used for high productivity and its applicability to systems automazione.E 'an autogenous welding process in which the arc strikes between the workpiece and the wire fusibile.Il wire feeding device provides a continuous feed into the bathroom (as opposed to the stick electrode which, when completed, should be replaced with a new wand). The protective gas is supplied directly to the molten bath, a gas holder.

mode of transfer of material filler.
By welding equipment, and thus setting the parameters of voltage (V) and current (A), can be obtained under different conditions of material transfer.
Spray Arc (Arc Spray): continuous stream of droplets, free. Used with high current values, good quality and good appearance, condition stable arc.
Globular Arc (Arc Globular): free large drops with lower frequency, obtained with current and medium-sized detachment of the drop due to the magnetic field gap, welding is not fair to look. Short Arc (Short Arc): posting big drops that short-circuit, obtained with low currents, used for welding in position and fill.

TIG
General
The TIG welding process is a process of fusion welding, autogenous. The electric arc strikes between the infusible electrode, which is under protective gas, and the material being welded. The electrode of the TIG is Tungsten, high melting temperature material with excellent emission properties termoionica.Il TIG welding process can be manual: with a length of arc welding and electrode-controlled, semi-automatic: arc length and electrode controlled by the machine, while the welder moves the electrode along the seam, automatic, all operations are carried out by Robot.
It has a stable arc that allows good control of the weld pool. However, the TIG is a very productive process used to thin. It can weld all types of metals and nonmetals using as filler or even a stick, thanks to a lot of energy focused arc, just to weld the two ends side by side, without using filler.
ElettrodiGli electrodes used for the TIG welding process are of four types: pure tungsten electrodes

tungsten electrodes with added oxide tungsten electrodes thoro
addition of zirconium
tungsten electrodes with tungsten stripes thorite

additional protective gas
Especially in the welding of Titanium, you should take extra precautions to help protect the cord from any surface oxidation. The "shoe" is an additional protective gas covering a stretch of the cord being raffreddamento.Nel case of solder of stainless steel tubes, the first pass should be protected by creating an inert atmosphere inside the tube while in the case of butt welds, you should create a support gas on the reverse. These additional protections
gas, as mentioned, are all used to protect the weld from possible attacks of the weather.


Benefits
E 'can weld almost all types of ferrous and non ferrous materials also

high quality of welds used in all welding positions
does not produce slag
Disadvantages
Reduced protection of the bath electrode compared to procedures or under flow
sensitive to air currents
high cost of gas protective
Low productivity
technique difficult to learn
Typical defects of the process TIGI types of typical defects we're going to have with the TIG process are:

oxidation of tungsten inclusions cord to the back (if they have not been taken care of gas protection).
inclusions of gas, due to poor cleaning of the edges and poor operating technique in the movement of the torch and baton.
Contamination of protective gas.

COATED ELECTRODE
General principles
welding with SMAW welding process is the most widely used both in mechanical engineering as a metal structure is suitable for welding of almost all ferrous and nonferrous metal alloys other than aluminum alloys. This is a very versatile procedure which is produced an electric arc between an electrode "Consumable", suitably covered, and the workpiece. The drops of molten metal from the electrode is transferred through the arc, the weld pool and gases from the coating to protect the atmosphere. The molten slag that floats above the weld pool protects it from the atmosphere during the welding process solidificazione.Il electrode is well suited for welding in all positions and, thanks to the simplicity of the equipment, for use in many situations, at the construction site or in confined spaces. In the face of operational advantages, however, we have a poor productivity record, in fact, the electrode has a reduced length and must be frequently replaced.

Oxyacetylene
GENERAL '
E' a process of autogenous welding by flame. The gas used is a mixture of acetylene and oxygen that can reach a very high temperature (3030 ° C). Despite being a fairly simple welding system, widely used in workshops and at site because the necessary equipment is not bulky and allows for welding in awkward positions, rather, on pipes in the first passata.Con this technique has a good distribution of heat on the surface to be welded also the flame is rigid and thus well against orientabile.Di 'widespread and high heat, heat affected zones generates very large and high thermal shrinkage. The process shall be limited to the welding of reduced thickness, is then used for welding of thin pipes not shown and sheets of between 6 and 8 mm.
EQUIPMENT
oxygen and acetylene cylinders are provided by the oxyacetylene connected by hoses equipped with valves security. The flow is controlled by valves located at the end of the handle, in which the gases are mixed in required proportions and then pass through the nozzle and the nozzle exit: it is interchangeable so you can adjust the size voluto.La the type of flame combustion of the two gases is the exit of the torch, the flame must be adjusted according to material to be welded to the protective gas atmosphere to be applied.

The flame can be divided into three zones:



A first area is immediately adjacent to the nozzle of the torch, here is the fact that the first combustion primary combustion. Acetylene reacts with oxygen supplied from the tank and form carbon monoxide and hydrogen, at this stage, do not participate in any reaction. In this first reaction, because of the insufficient amount of oxygen that comes out of the torch, there is complete combustion of acetylene, and the exothermic reaction provides about one third of the total heat generated by the complete combustion of acetylene. The primary comustione is visible as a small cone called "sting" in which the temperature is about 1200 ° C.
The complete combustion occurs in the immediate vicinity of the dart with oxygen around the flame itself resulting in a secondary combustion which points to a new area called the flame reducing zone, here the carbon monoxide released dall'acetilene again reacts with 'oxygen, which this time comes from the environment to form carbon dioxide and hydrogen, also released in the first stage, reacts with atmospheric oxygen to form water. Although these reactions are exothermic and are responsible for two thirds of the total heat generated by the complete combustion of acetylene. In this area the temperature is about 3100 ° C.
Development heat and keeps the final products at high temperature resulting in more light gases and vapors produced until, with the drop in temperature the effect wears off, this area is called plume, and is characterized by a temperature to 2400 ° C.

Conclusions

The premise of this project is to provide educational students, through the use of a PC, the opportunity to learn actively and not formalized.

The student, in fact, can also be made easier to understand complex and abstract concepts as long as they have provided tools that enable them to manipulate the operating and concrete. A knowledge that is constructed actively. In this way we can ensure that the lessons can be adapted to the learning process of students and is no longer just something to learn, but to use. The ease of use by the children of a PC is used in a didactic: to show that the things they do are important, focus on their involvement and skills to achieve good results, appreciate the commitment and participation, are weapons to improve learning and relationship. It is also believed that the group work with the PC is particularly suited to the strategies of "collaborative learning" in which students are placed at the center of a community of learning and the teacher's role of guiding and facilitating learning. The work of building a group that learns, exchanging, sharing and enhancing the capabilities of each of its components, is the most appropriate educational activities to be implemented with the help of PC. It thus encourages the transition from a teaching transmission, to a more vertical part, horizontal. There should be more transmission only "vertical" exchange of knowledge, but also "horizontal" the same; factor that imposes the need for and enhanced communication.

I hope this film gives the risultali expected.

Thank you for your attention Mr. Vincenzo Sciarra

FIXED CONNECTIONS: WELDING

SHEET LESSON 2
WELDING

GENERAL
Welding is a process of joining two pieces of metal, through the action of heat-done realizzan continuity. The weld can be obtained with or without a - the filler, which can be supplied in different ways in different processes used.
In common parlance, the term also indicates the welding area where we realize the connection of the parts. The welding has had in recent years a significant development, almost completely replacing the mark-welding (metal structures), for complicated operations merge, forging and stamping (Drop in bank machines and parts with difficult geometries) and some long working machine tools (in pieces flanged).

Benefits welding
The welded joints the following advantages when compared to those spiked :
-greater speed, since the preparation of the edges to be welded is easier than 'make holes for studs

-less weight and less cost-
increased strength (nail holes weaken the structure)-
easier to edit (with added reinforcement elements also work).
welded structures have the following advantages compared to cast :
-complex structures are obtained without the need of the model are still necessary for mergers
-structures can be obtained from parts of different thicknesses, without generating fissures and cracks.
-you can make parts with parts made from materials with different characteristics.
-l 'welding operation is faster, lighter, less dangerous and less polluting than the merger.
With new technologies it is possible to weld all materials commonly used in construction, such as steel, cast iron, aluminum and its alloys, copper and its alloys, zinc, lead.
is generally guaranteed a liaison resistance equal to that possessed by a whole piece is built with the same material. The pieces obtained
complex welding process are usually subjected to heat treatment following relaxing and standards, to remove the internal stresses arising during cooling of the joints.

Classification of welding processes
(UNI 1307-1st part)
are reported in schematic form the various welding processes listed in the table UNI 1307-the first part. According to this rule, the welding process can be divided in two groups:
autogenous welds, those in which the connection is made to partial melting of the edges to join, with e-ventuale adding more filler.
In these welds is made struc-tural continuity between the pieces to be welded.
heterogeneous weld (braze welding brazing), those in which the connection is made by casting the only filler that stands between the edges to join, which do not melt even in part.
In these welds is carried out structural continuity between the pieces to be welded.
A more detailed classification of the welding provides a breakdown of the four categories below.

Fusion welding arc

- free air electrode fuses, arc-sommer know, protective gas

MIG (Metal Inert Gas), MAG (Metal Active Gas), electrogas
- not fuses electrode TIG (Tungsten Inert Gas)
- to plasma (transferred arc)
gas

electroscope to a focused light
-
laser - light arc

resistance welding
points
to sparkle
roller
high frequency induction
reliefs

head to head with sparkling


welds for ultrasonic pressure

diffusion

for friction pressure gas to boil

cold pressure
Electrical discharge in explosion



Brazing Brazing
soldering brazing


As you can see, the welding procedures are many and diverse enough to be an important part of the technology, which are still evolving.

TYPES OF JOINTS WELDED
(UNI 1307 - 2nd part)
welded joint is defined as the part in which the connecting pieces by welding.
lower surfaces of the pieces, and affected close to welding, are called heads or limbs or edges, these May-Giori are called faces.
The relative position of parts welded to define the type of joint, where the choice is made according the existing building needs or overall functionality of the IN-welded together.
The main types of joints are shown in fig. 2.1

PREPARATION OF WELD JOINTS
(UNI 11001) 11001 UNI
The table presents the code of practice for the preparation of the flaps for fusion welding of steel structures. This code provides guidance for the choice of work to be done on the edges of the plates, with the aim of:
ensure good penetration of the bath-sion was
facilitate the welding operation for the various pro-yielding
adopted to obtain a correct positioning of the sheets forming the chin mutual coupling, even after welding
The work to be done on the edges to be welded are
the crimping process: preparation of the edges to be joined with contoured surface;
smoothing: task of preparing the edges to be joined with a flat surface.
With reference to fig. 2.9 can give the following definitions.
bevels : space between the edges to be welded, born destined to be filled by the filler.
Profile: cross section of the bevels.
Lembi: surfaces of the plates bordering the bevels.
Summit: area where it is made the first pass of welding, the one farthest from the welder.
Shoulder: portion of the strip that borders the bevels in the vicinity of the summit, parallel to the corresponding section of the other flap.

LINKS FIXED: FIXED nailing

SHEET LESSON 1

nailing nailing is a process that allows you to combine elements in a stable and definitively by the use of nails.
The operation is to drill holes on the elements to connect, which will be tucked inside the nails; the connection is made by riveting stem protruding.
The riveting can be done either hot or cold. The process of riveting, hard-working technology is so expensive, is made in cases where welding create structural problems (lack of heat treatments on weldment).
The nails can be of three types.
The nails strength and sealing are carried out on containers (high-pressure tanks, boilers, autoclave-vi, penstocks), whose mission is to support and considerable efforts to ensure a tight seal. The rivets holding
are required to ensure that the seal in the presence of small efforts (low-pressure tanks, gas holder, fireplaces).
The riveting force run when you need to fix problems without considerable effort required (metal construction carpentry, trellises, sheds, decks).

The nail is a mechanical device consisting of two basic parts: the head and stem .
The head is available in the forms provided by the unification-ment and the truncated conical shank is protruding with respect to the elements to merge, a part intended to be riba-fingers (hot or cold) to form the other head.

Fig.1.1 nail before and after the riveting


The nails are divided into:
nails (proper) and when the stem has the diameter greater than 8 mm; Ormala are hot riveted.
rivets (or rivets), when the stem has a diameter less than 8 mm are repeated cold.

Head size and head shapes characterize the different types of nails in Table F3.1 with its fo-ri preparation, to be achieved on the elements that combine in the head and hand riveting.
Stem The stem is a truncated cone (taper 1:50) to facilitate its introduction into the holes. The riveting hot nail generates compression between the two heads of the elements to be joined, and this effect is then enhanced by the contraction of the stem during cooling. Therefore, the nails are not only encouraged to cut, but also traction along their axis and the joint efforts between the two transmit elements by friction. The
UNI tables provide for the nails the following tri-diameter, expressed in mm:
8 - 10 - 13 to 16 - 19 - 22 to 25 - 28 - 31 - 34 - 37 to 40
Material Nails are made of steel extra sweet, with ele-vated capacity of plastic deformation (elongation at fracture of 25%).
is important, however, that the material is fragile or hardenable. For this reason we also use copper nails, brass or light alloy.
Forum The hole diameter is slightly larger (from 0.5 to 1 mm) of the shank of the nail. The hole on the elements that unite can be achieved by punching or drilling. Punching is cheaper because it faster, but it can damage the material deforming the contour of the hole. The drilling, coupled with the bevel of the edges, it is essential for holding nails.
Forms nailing The union of two elements can be made by nailing in the following ways, each of which has its own practical formulas for sizing:
nailing
simple overlap - with a row of nails (fig. F 1.2)
- with two rows of nails facing (F 1.3)
- with two rows of nails staggered nailing a simple joint cover (slightly used)
- with a row of nails
- with two rows of nails staggered.


Fig. 1.2 nailing with a single row of nails
Fig. 1.3 nailing single with two rows of nails

Designation of nails
The designation of the nails include:
- the word nail (not compulsory)
-
of the diameter - the length of the stem before
- the material.

example of designation of the nails
Chiodo 13 x 45 UNI 2514 - C10
nail countersunk head cap
reduced shank diameter d = 13 mm
stem length l = 45 mm
steel material C10.


Nails Special
In applications that require serial quick installation and require no great stretch of the ra-closing mechanics, special nails are used (see Table F3.1), such as nail slots Round head (UNI 7591) and slotted (UNI 7592) or nails High resistance button head and neck tightening, as projected by recent chart UNI 8646 (Fig. 1.4)


Fig . 1.4 Nail Special with adjustable collar

The implementation stages of the nail with clamping hub are:
1) is part of the nail holes of the elements to join
2) pulls on his collar sticking out part Stem
3) you put tension on the nail, holding it by the tail with a special tool
4) it presses and deforms the collar up to engage the grooves heating sal-tightening
5) tears of the tail wheel, causing the breaking-ra in correspondence with the groove


Rivets Rivets are nails shank diameter normally less than 8 mm, still riveted cold. The riveting
cold generates compression between the two heads of the elements to merge. Compared with nails missing, in this case, the contribution to the compression due to contraction of the stem. UNI
tables provide the following for rivets diameter, in millimeters:
0,8-1-1,2-1,4-1,7-2-2,3 - 2.6 - 3 - 3, 5 - 4 - 5 to 8
The material they are made rivets can be mild steel, aluminum, copper, brass, alloys leg-gere. Some rivets lead in a head-ment contracted specification of the material (Fig. 1.5),
The description of the rivets is performed with the same information already described for the nails.
widely used, even if not unified, are ribat-tini expansion. They have the prerogative to be able to be realized between the closure elements that do not allow access to the stem from stress, but that is retracted using different techniques (Fig. 1.6)

GROUNDS EDUCATIONAL TECHNOLOGY MECHANICS

develop and organize in a more systematic way can gradually become more specific objectives in several UD in a step by step, we try to develop in students the ability to understand, analyze, synthesize , evaluate, and / or criticize what has been proposed in the UD

doing so, the UD will be structured, following a logical segmentation, that is an evolutionary sequence, aimed at achieving specific goals.

In the first phase of the argument will be presented, following if possible, the deductive method.
In relation to the skill level of the preferred goal, will be administered the test or other tests to check that aim to verify the objectives of cognitive ability or class. The test results and other evidence given at the end of the UD may give information on the progress achieved and the level of learning by the class. While these results should indicate difficulties for individuals or groups, recovery mode, the other gradually added to the results obtained during the teaching year, should lead to appropriate changes in teaching strategies implemented in that particular course of study.
The time of the assessment is an aspect of the itinerary of instructional design closely related to other moments of this process, namely, the phase detection levels, as well as the choices of content, tools and methods and the formulation of objectives. The assessment is no longer therefore be considered as a separate time from the final assessment of the product of learning. In planning educational assessment itself is quite an important educational teaching basic route planning as a whole.
The translation of educational goals in cognitive objectives and operational objectives (in the planning of the whole course and individual units) if it is true that meets the needs to make in some way to verify the results achieved in the experience of learning skills such as school pupil himself, also tends to verify the effectiveness of teaching the same procedures in place. It is for these reasons that already during the preparation of hearing, identifying the sequence of intermediate and final goals that pupils should achieve than foreshadowed content based on levels of departure, are outlined in relation to each objective and materials and individual procedures, policies and procedures adequate monitoring and evaluation.

presentation

This blog is intended to enhance the course of Mechanical Technology for technical and vocational institutes to address mechanical. Before turning to the various stages leading up to publish the syllabus, I think it is essential to define the general objectives that should put a teacher in mechanical disciplines and then, to reflect first on the nature of the discipline and the positive effects that learning can be on general education students. It is essential, in fact, make them understand the importance of this matter for their professional training.

Discipline Mechanical Technology performs without a doubt the their commitment to training the pupil, and is what is most relevant to everyday working life. This discipline encourages the student to actively participate in classroom activities and contributes to informed choices and to prepare future leaders in the company, where he must make concrete what he learned in the classroom.
