YAG LASER INDUCED ARC FILLER WIRE COMPOSITE WELDING METHOD |
摘要 |
A combined welding method with a filler wire using both a YAG laser and an electric arc, and a combined welding device with a filler wire using both a YAG laser and an electric arc, a welding in which a welding gap margin is broad, height and shape of reinforcement of weld, and penetration depth are preferable, can be effectively performed by the method or the device. The welding is performed by directing a laser focus 8 of a YAG laser 9 on base materials 31 and 32 for welding or the vicinity of the focus 8 by a filler wire 20, connecting a power source 22 for applying a voltage to the filler wire between the filler wire 20 and the base materials for welding, irradiating a YAG laser on the base materials for welding in the connecting condition, whereby an arc is induced to the filler wire by a plume (plasma-activated gas and the metal vapor), and holding the plume generated by YAG laser inside and outside of a keyhole. <IMAGE> |
