TIG welding, alternatively called gas tungsten arc welding, is one of the arc welding methods which is used to weld, above all, stainless materials, aluminium, and copper alloys. The products made by this method are usually of smaller proportions.
A great advantage of TIG welding is better control of the weld pool which, however, requires skilful welders with necessary training and certificates. We have such people in our staff and all our employees undergo regular trainings so that we can keep providing quality services on the highest level.
TIG welding is very similar to oxy-fuel welding. It uses non-consumable electrodes mostly made of tungsten or its alloys and, just as with MIG welding, inert gases are used to shield the weld pool as well as the individual electrodes.
When welding using the TIG method, the electric arc forms between the tungsten electrode and the base material. The generated heat then welds the edges of the base material, alternatively also the added metal.
Alternating current welding, referred to as TIG AC, is used to weld metals such as brass, aluminium, bronze, and alloys on whose surface some protective insulating oxide layer can be expected. For example, this technique is used frequently with aluminium welds because despite the melting point of aluminium being 650 °C, a thin compact layer of aluminium oxide can be found on its surface, the melting point of which is over 2000 °C.
