Abstract The thermal physical process of bypass coupling micro plasma arc welding in additive manufacturing process was studied. Concretely, the thermal cycle curves were measured by K type thermocouple at various welding speeds, bypass currents and stacking sequences in stacking forming. And the influence of each parameter on the thermal process was analyzed. The results show that the heat input of the base metal declines with the increase of welding speed. In appropriate range of bypass current, enlarging the bypass current can reduce the heat input of the base metal. Meanwhile, the unidirectional stacking shows better heat dissipation than reciprocating stacking. The control of thermal process of bypass coupling micro plasma arc welding in additive manufacturing can be realized by precise control of bypass current and reasonable plan of stacking path.
