Electric Contact Sensors

Dec 13, 2016

Following a determined searching strategy, the electric contact sensor systems are scanning the weld start or other track points via contacting the work piece with parts/components which have been subjected to voltage (direct voltage of several ten Volt up to 1 KV, depending on material and surface) of the welding equipment (shielding gas nozzle, welding electrode, stylus, or similar.) This means the offline-measuring of the weld start, the part position or part geometry before welding. Knowing the scheduled path, a transformation of the track points in accordance with the measured conditions is carried out. In this case, corrective action is not carried out during the welding process.
