In the TIG process the arc is formed between a pointed tungsten electrode and the workpiece in an inert atmosphere of argon or helium. The small intense arc provided by the pointed electrode is ideal for high quality and precision welding.
As the tungsten electrode is not consumed during welding, the heat of the arc will melt the base metal and a separate filler rod can be added into the weld pool if required.
Castolin has developed the special CastoTig alloy range for industrial wearfacing, repair and joining applications supported by a complete high quality, CastoTIG welding equipment range based on latest technology.
