Abstract

PURPOSE: To improve the semiautomatic welding sense and uniformity of a bead by promoting shaking of a molten pool overlapping pulse voltage of a speific current crest value, which is lower frequency than the pulse MIG welding method, to said method.
CONSTITUTION: The transformer for supplying pulse voltage 1 delivers the first pulse voltage of commercial power supply or its twice frequency to the consumable electrode 11, and gives the current wave form Ip1. Pulses synchronizing with this wave form are inputted to the counter 13, which is set the number of count by the circuit 14, from the generating circuit 12. A count end signal at the time when said count number reaches a set value is added to the wave forming circuit 15, and forming of a wave form is made. On the other hand, with said signal, resetting of the counter 13 is made repeating the same operation again. Also, said signal is added to the gate circuit 16 of SCRs 2 and 3, and the gates G1 and G2 are controlled. Then, the second pulse voltage, which has a lower frequency and its crest value is 1.5W2.0 times comparing with the first pulse, is generated. Thus, the current wave form Ip2 can be obtained, and shaking of a molten pool is promoted.
