| Pioneering Fault Detection (PFD)
online analysis of the arc dynamic - patented technology for WeldQAS systems The PFD technology is based on an evaluation of a process index. It recognises the low differences in welding current and welding voltage at irregularities during the welding e.g. - weld seam besides the joint, - pores, holes lacks of adhesion, penetration defects or - influence of gas and wire The process index is - calculated online only from the high-speed trace of current and voltage, - widely independent of the welding current and - doesn't need automatically learned patterns. The result is a reference value for the monitoring of the automatic production and a indicator for the analysis of the arc |
