Title: High frequency electric seam welding method
Inventor: HAGA HIROTSUGU
IPC: B23K13/08
Filed: 1986-03-03
Abstract: PURPOSE:To prevent the welding defect of a product by electrifying intermittently or high-loweringly periodically a high frequency current at the specified time intervals. CONSTITUTION:An electrification period, the ratio of ON period, OFF period, etc., are set at the prescribed values by arranging the switching element 14 of a transistor invertor, etc., between a direct current power source 12 and upto the anode of an oscillation tube 13. The high frequency current of electric seam welding is passed via this device intermittently or high-loweringly periodically at the time intervals of 0.1sec from 0.1msec. In this case, the electromagnetic force induced by the high frequency current can be dissipated or reduced at almost fixed period. In this way, the generation of penetration based on the cool contact or high heat input of the high frequency weld zone can be prevented. Consequently, the generation of the welding defect of a product can be prevented.
