Where & When to use TIG / GTAW Welding Process

Tungsten Inert Gas (TIG) or Gas Tungsten Arc Welding (GTAW) welding process is used where more weld strength is required & where fine weld finish is of utmost importance.

In TIG welding process, tungsten electrode is used as a media to create an arc along with suitable shielding gas. Now, here tungsten electrode plays a very important role. Since tungsten electrode is itself a very hard metal, it creates a very fine and stable arc resulting in strong and fine finish weld joint, which we mentioned above.

TIG welding can be done on any metal using suitable filler material. Here, one should be cautious while selecting the filler material. The filler material chemical composition should be as near as possible to that of the base metal. So ask for the composition chart from the supplier & match the same with the base metal composition. The benefit of similar composition would be that the weld pool created during welding would have atoms that would mix very easily thus, creating a strong weld joint.

Clean TIG Filler Weld results

Another very important aspect one should definitely consider while selecting filler material is that the same should be free from dirt (grease, oil, paint, sand particles, plastic contamination) and rusty metals and other forms of corrosion which may produce weaker weld joints (porosity and joint cracking) and makes the welding task difficult. Clean base metal is of equal importance.

Weld Bead Profile

ARCON filler rods are surface treated using biodegradable chemicals for deep cleaning to remove all surface contaminants (even from pores) to produce strongest and more durable weld deposits. Mere spray water jet cleaning is not enough since it is not capable of deep cleaning. In short, the filler material should be of natural color as that of the raw material from which it is made. Surface shining is not of any importance.
