In this paper various metal transfer modes in the pulse MIG welding with steel electrode are studied by means of high speed cine camera and oscillograph.
Measures were taken to prevent welding cold cracking such as improve welding technology by decreasing cooling speed and adopting low-hydrogen electrode, etc.
