TIG (Tungsten Inert Gas) welding is a welding process that uses a tungsten electrode and an inert gas (usually argon or argon/helium mixture) to protect the weld area from impurities. It is often used to weld materials such as stainless steel, aluminum and copper. To perform a TIG weld, an operator uses a torch that includes a tungsten electrode, an inert gas and an electric current. The operator holds the tungsten electrode in his hand and directs it to the welding area, while the inert gas is used to protect the welding area from impurities. TIG welding is particularly valued for its accuracy and weld quality, making it a popular choice for demanding welding jobs. However, it requires a high level of operator skill and is generally more expensive than other welding processes. In summary, TIG welding is an accurate and high quality welding process, but requires a high level of skill and is generally more expensive than other welding processes. A complete guide to understanding how TIG welding works
First of all, this is the question I have to answer. When we talk about welding, it is the action of fusing two metal (or plastic) parts thanks to heat. There are several welding processes and the most common ones are detailed below in this page (you can access them here!). In general, an electric arc is used to make our metal parts go from a solid state to a liquid state. Once the molten bath is created, the goal is to add a filler metal. The whole process is done under a gas protection that will avoid the contamination of the welded joint by particles present in the atmosphere.
Welding is in constant progress, its development is permanent in all modern industries today. The constructive requirements are important both quantitatively and qualitatively. The company and its welding technicians are confronted with systematic controls at all levels of production. Welding standards are updated every five years in Europe. Each member state of the European Union can comment on a certain standard, approve it without modifications or ask for its cancellation because it has become obsolete in relation to the new technologies and techniques of the moment.
The welder can be called for two types of intervention: New work. Repair or maintenance work. New works. The welding works can be carried out on : boiler works (assemblies made of metal elements previously shaped), in ordinary or stainless steel; mechanically welded assemblies, in non-alloyed or stainless steel. The assemblies can be made on sheet metal or on tube, with or without support, according to the standards in force, the quality class chosen and the specifications defined in the welding book. Repair or maintenance work. The components of machines, guiding or conveying systems can break down due to thermal and/or mechanical fatigue. In most cases, the parts to be repaired are contaminated with fatty materials (oil, grease) or materials with which they have been internally or externally contaminated. The parts to be assembled must be free of any contamination. The welder shall therefore: Degrease using an appropriate solvent (trichloroethylene, acetone....) Strip by grinding or sandblasting. Search for possible micro-cracks by dye penetration or magnetic particle inspection techniques, or even by radiography or ultrasound if he has to carry out a high security assembly.

Stick welding consists of a rod of material covered with a flux. The rod is used here as an electrode in the electrical circuit. Melting is achieved by a very high temperature which is obtained by an electric arc between the workpiece and the electrode. The main functions of the electrode coating are to ensure the stability of the arc and to protect the molten metal from the atmosphere. with the gases created during the decomposition of the coating by the heat of the arc. This shielding controls the mechanical properties, chemical composition and metallurgical structure of the weld metal, as well as the characteristics of the electrode.Welding processes
The welding vocabulary is very clear to understand quickly, for the weld bead we use the same words for all welding positions. The two metals to be joined will be called "base metals", while the weld bead will be a mixture (molten metal) of these base metals with the filler metal. The base metals can be homogeneous (of the same nature such as steel to steel, copper to copper...) or heterogeneous. Sometimes you may need to weld different types of steel. For example, on buckets fitted to public works machinery, it is possible to build the structure of the part in basic structural steel (S 235) and to reinforce the tooth or blade with much more wear-resistant steels such as hardox 500.Weld bead
An important aspect of heat flow is the study of the cooling rate in welding. These speeds, of the order of several tens of degrees per second, are different from those encountered in other fields of metallurgy such as steelmaking and foundry where the magnitude control is a few degrees per minute.Weld bead in depth
