The different welding techniques and their specificity

Welding is one of the jobs that requires a lot of attention. It requires a good preparation. In addition, the welder must have the required skills in performing the welding. This guarantees the quality of the work. But it is also very important to know the welding technique to adopt. This depends on the type of metal to be joined. Indeed, each method has its specificity. Thus, it must be well chosen. Which technique for which assembly?

TIG welding: the technique that offers a quality weld

TIG (Tungsten Inert Gas) welding is a technique that uses an electrode, an inert gas and an electric arc to assemble parts. The electrode used is non-fusible. This is why the welding process requires the addition of metal.

This is one of the methods in the welding mechanics suitable for alloys, heterogeneous assemblies and all types of metal. Indeed, it is both flexible and reliable. Moreover, with this method, the welder can make aesthetic and solid parts. In addition, it offers a precise welding.

During the welding process, no residue is projected on the material, no sparks or splashes. This means that the technician does not have to rework the parts.

Regarding its use, TIG welding is often used to restore a car or to design metal frames for furniture. It is also well suited for welding thin plates.

Electrode welding: the right method for outdoor welding

Electrode welding is also called electric welding or arc welding. To bond metals, this method uses electrodes. For this, they must fit the metal to be welded and have a similar melting point.

One of the advantages of this method is that it can be done outdoors, even in strong winds. In addition, the welder does not need a gas cylinder when welding, as the gas is already integrated in the electrode. This welding technique can be used on all types of steel and stainless steel. However, it is not suitable for aluminum.

This method is well suited for quick repair or maintenance work. That's why it is used by do-it-yourselfers or the companies who perform small welding jobs on a daily basis.

MIG/MAG welding: for precise and efficient welding

MIG (Metal Inert Gas)/MAG (Metal Active Gas) welding is a technique that uses the fusible electrode under inert gas (MIG) or active gas (MAG). For both techniques, the welding process is the same. But the difference lies in the type of gas used (inert or active).

It is the most popular welding technique. Indeed, it allows to weld large surfaces in a short time. It can also be applied to several types of steel and different thicknesses. It is automatically fed with wire.

Thanks to these different advantages, this welding method is well suited for large repetitive welding jobs. It is used in theindustry and large companies.
