摘要

Improved arrangement for the unión by welding tig of stainless steel tubes in heat exchangers, with an automatic head (5) in a "U" shape with tig welding that completely covers the parts to be welded avoiding the escape of the inert gas that is confined in a camera (7); to achieve a welding with a very low leak rate, the two ends (4) of the elbow (1) are formed, increasing its outer diameter and chamfering its tip (4a), the parts to be soldered with acetone are cleaned, to eliminate any grease residue, and are introduced in the ends (3) of the tubes (2) to be joined, which are also widened, and proceeds to the welding with the automatic head.
