rod welding, joins metals by melting base and filler metals with an arc struck between a tungsten electrode and the workpiece. The tungsten electrode is a non-consumable electrode and does not become ...

It’s right in the name. TIG welding uses sintered tungsten electrodes; rare earth oxides reduce the work factor to make striking arcs easier. Source: Adobe Stock. Another important industrial ...

Aspiring TIG welders very quickly learn the importance of good tungsten electrode grinding skills. All it takes is a moment’s distraction or a tiny tremor in the torch hand to plunge the ...

Plasma welding is similar to Tungsten gas (TIG) welding. In both processes the arc is formed between the end of a small diameter tungsten electrode and the workpieces, but in plasma welding the ...
