摘要： The present invention provides a novel method and system for tool breakage detection during the friction stir welding procedure on an automated friction stir welding machine. The object of this invention is the integration of an accelerometer sensor which detects tool breakage events in real time and triggers a preprogrammed reaction of CNC controller. In this way, a complete destruction of welding tool is prevented. Another object of the present invention is to provide an automatic reaction of CNC controller that is triggered by an error signal and consequently prevents N.O.K parts with welding faults from entering further production steps.

摘要： The present invention provides a method of friction stir welding with detection of a tool (2, 15) breakage detection on an automated friction stir welding machine. The problem is solved with the integration of a laser distance measurement system (13), which is employed at the end of the welding sequence to verify the presence of a tool exit hole (16). Also presented is an automatic execution of a subprogram which enables the exclusion of non acceptable, i.e. N.O.K., parts in which a tool (2, 15) breakage incident occurred.
