The metal produced in the weld pool is a combination of filler and parent metals that must have the strength, ductility, freedom from cracking, and the corrosion resistance required by the application. The tig wins flat out on titanium and some alloys of aluminum, like 5086 and 5083. I welded two tubes together then took a sledge hammer and smashed them apart.

Tungsten inert gas (tig) welding, also known as gas tungsten arc welding (gtaw), is best suited for welding aluminum and stainless steel. I prefer to tig whenever i can, but there are times when mig with a spool gun is the way to go. But 1.5 amps per thousandths along with a.
