Title (EN) MIGRATION ARC WELDING PROCESS
(FR) PROCEDE DE SOUDURE A L"ARC PAR MIGRATION
Abstract: front page image
(EN)A welding process, more particularly, a migration arc welding process which eliminates adverse effect of mixed inert gases upon the results of welding by greatly improving the arc stability when the migration arc welding is applied in pure inert atmospheric gas. The essential point of eliminating the problem contains the inclusion of small amount of rare earth elements as a welding wire, use of a pure inert gas atmosphere, and migration of molten droplets, produced by arc heat, toward a base plate, particularly in an instantaneous contact shorting state. This process can be applied generally to joint welding processes.
(FR)Un procede de soudure, plus particulierement, un procede a l"arc par migration elimine les effets nocifs des gaz inertes melanges en ameliorant considerablement la stabilite de l"arc lorsque le soudage a l"arc par migration s"effectue dans un gaz atmospherique purement inerte. Le point essentiel pour resoudre le probleme consiste a inclure une petite quantite d"elements de terres rares comme fil d"apport, a utiliser une atmosphere pure de gaz inerte, et une migration de gouttelettes en fusion, produites par la chaleur degagee de l"arc, vers une plaque de base, en particulier dans un contact instantane de court-circuit. Ce procede peut etre applique generalement a des procedes de soudure de joints.
