摘要
A method is provided for monitoring and controlling the process consistency of an arc welding process. The weld voltage signal is monitored and analyzed to determine the occurrence of the detachment of a weld droplet. The weld droplet detachment is determined via statistical techniques as having occurred at a normal interval following a prior detachment indicating consistent weld process or as a sporadic detachment having occurred at an irregular interval with respect to the prior detachment and indicating inconsistent weld process. The weld process is adjusted by controlling the weld process variables to maximize the predominance of droplet detachment at normal intervals and minimize the occurrence of the sporadic detachments.
