METHOD OF AC ARC WELDING WITH NON-COMBUSTIBLE ELECTRODE Russian patent published in 1994 - IPC

Abstract RU 2012461 C1

FIELD: welding. SUBSTANCE: in ac welding with the use of non-combustible electrode and filler metal, the latter is fed by pulses. When feed of filler metal is interrupted, welding zone is subjected to the action of pulse magnetic field. In the course of filler metal feed welding is effected under helium atmosphere and at the moment, when arc zone is subjected to the action of magnetic field it is effected under argon. Relation of helium feed duration to argon feed duration is selected within the range from 0.8 to 1.5. EFFECT: higher quality of welding. 1 tbl, 1 dwg
