TIG welders, gas tungsten, heliarc tig welding machines, welder information (612 words)
TIG welding is a manual welding process that uses a non-consumable electrode made of tungsten, an inert or semi-inert gas mixture, and a separate filler material.
TIG may be used without the addition of a filler metal or a separate wire filler metal can be added into the puddle when additional material is required, much like the process in oxy-acetylene welding.
TIG also produces a welding heat is that is confined between the weld and base metal at the point of fusion and produces a narrow heat affected zone.
