Conventional pulsed gas metal arc welding (GMAW-P) achieves stable and repeatable spray transfer by using correct pulse parameters. Since the optimal pulse parameters depend on welding parameters, a control method that delivers one drop per pulse (ODPP) transfer in a robust and repeatable manner is proposed in which the droplet starts to oscillate by first moving toward the weld pool. As a result, the detaching pulse can be applied after a very short period of time and the combination of increased electromagnetic force and downward momentum is guaranteed. Thus, the control system is simplified and the metal transfer is robustness is further improved.
