Abstract： |
An arc-ultrasonic welding method for Ti alloy features that an arc-ultrasonic exciting source using electric arc as heat generater and ultrasonic emitter is parallelly connected with the conventional power supply used for arc welding. The ultrasonic waves can act on the molten bath on the workpiece to be welded to improve the smelting and crystallizing procedure of Ti alloy for finer crystal grains and higher welding strength and fatigue resistance. |
