METHOD AND DEVICE FOR PULSED ARC WELDING

摘要

The invention concerns a method and a device for pulsed arc welding in which the electric current has conductance with pulse droops and/or pulse rises between 50 A/ms and 1000 A/ms, and more particularly between 100 A/ms and 500 A/ms, with the exception of a triangular pulse. The invention is applicable to MIG or MAG welding.
