Abstract

The invention concerns an automatic method and installation for multiple plasma jet welding of two metal parts, such as the edges of a tube. The two parts to be welded are assembled along a joint plane. The method consists in generating a first plasma jet exhibiting a first linear welding energy ( DELTA E1) with positive and non null value; generating substantially simultaneously a second plasma jet exhibiting a second positive and non null linear welding energy ( DELTA E2); optionally generating a third plasma jet exhibiting a third positive and non null linear welding energy ( DELTA E3); and welding the two parts, one with the other, by subjecting the joint plane to be welded to said first, second and, optionally, third plasma jets. The invention also concerns the use of said method and installation for making metal tubes.
