WHERE ARE THE MIG WELD PROCESS CONTROLS?
USING THE WRONG WELD TRANSFER MODE: The MIG weld transfer mode used for the majority of your robot and manual frame welds is the “globular weld transfer mode”. This weld transfer mode produces poor weld fusion, poor weld deposition rates, erratic weld transfer and extensive weld spatter. None of the traditional controlled MIG weld transfer modes, short circuit, pulsed or spray are being utilized. Globular Fillet Welds on the Frame.This globular, robot fillet weld with extensive lack of weld fusion was considered an acceptable weld and was not subject to manual weld rework Management / Engineering Issues: While in the plant I had many opinions presented to me on the causes of the extensive robot / manual weld process issues. In the eighteen months since this robot project commenced, the lack of management resolutions for most of the weld issues comes from the fundamental fact that the plant’s managers, engineers and supervisors involved, including your corporate project management, were
