How to Tig Weld?

Gas tungsten arc welding (GTAW) also known as tungsten inert gas(TIG) welding, is an arc welding process that uses a non consumable tungsten electrode to produce the weld. The welded area is protected from getting contaminated with the help of shielding gas and a filler metal such as aluminum or stainless steel. Gas tungsten arc welding can weld stainless steel and light nonferrous materials like aluminum and magnesium. Tungsten inert gas does stronger and higher quality welds when compared to its competing procedures like shielded metal arc and gas metal arc welding. Tig welding is complicated, difficult and much slower than other welding procedures like mig or arc welding.

Manual tig welding is considered most difficult among all the welding procedures in the industry. Because welding operator has to maintain a short arc length, make sure that great care and skill are required to prevent contact between the electrode and the work piece. TIG W elding generally requires two hands because the welder manually feeds a filler metal into the weld area with one hand while manipulating the welding torch in the other.

In the beginning, tig welding may be considered complex and difficult task but through regular practice and tuition it becomes easy for the welding operator to perform the task. In tig welding, very less cleaning is required, the finished weld is neat & tidy allowing an artistic feel to the work. Major examples of quality tig welds are bicycle frames, marine fittings, interior kitchen fittings and steel artwork.
