Development of Low Frequency Pulse MIG Welding Process for AL and its alloy
AL 및 AL합금의 저주파 PULSE MIG 용접법의 개발
Abstract
The low frequency pulsed MIG welding process of new current waveform control to switch over unit pulse conditions (pulse current, pulse duration) in the fixed cycle was developed and its effect were investigated for aluminium and its alloy. By using this new welding process, the bead appearance having clear ripple pattern, such as TIG welding bead can be obtained and the gap tolerance of lap and butt welding joint can be expanded.
