Method for monitoring a welding process during the welding of studs and device for carrying out said method

摘要

The invention relates to a method of monitoring the welding operation in a stud welding process, wherein a part ( 19 ) to be welded is immersed into the melt by moving the part ( 5 ) towards a workpiece ( 17 ), with a physical quantity depending on the force required for moving the part ( 5 ) being measured at least during the phase of immersion of the part ( 19 ) to be welded into the melt and the measured gradient of the physical quantity plotted against time being compared with a predetermined set gradient. Furthermore, the invention relates to a stud welding device for carrying out such a method.
