SYSTEMS FOR AND METHOD OF MONITORING A PULSED WELDING OPERATION BASED ON WELD SIGNATURES ANALYSIS USING PULSE FORENSIC FEATURES.

摘要

Systems (10) and method for welding are described. The welding system (10) includes a power source (30), a computer (20), and a welding torch (40). The computer (20) and the welding torch (40) can be operatively coupled to the power source (30). The power source (30) controls a wire feed and one of the current or a voltage to the welding torch (40). When the welding torch (40) is performing pulsed welding, the computer (20) is configured to receive a weld signature. The computer (20) is configured to synthesize features from the weld signature and to analyze the features for each pulse of the weld signature to determine whether particular limits have been exceeded or met. If particular limits are exceeded or met, a weld fault condition is triggered which causes the welding system (10) to stop or to modify the pulsed welding operation, and/or which causes the welding system (10) to send out communications relating to the triggering of the weld fault condition.
