TIG WELDING

TIG welding is commonly used for both high quality and manual welding. the process of

TIG welding involves an arc being formed between a pointed tungsten electrode and the
area to be welded.

• Creating a bath
Creating the bath is also possible without additional filler material, when required,
use for rods to add manually. The filling material must be compatible with the
workpiece material being processed, usually with rods.
