METHOD FOR DETERMINING ARC CONSISTENCY IN PULSED GAS METAL ARC WELDING SYSTEMS

摘要

A welding system, comprising: a welding torch comprising an electrode; a base unit configured to supply the welding torch with pulsed electrical signals for producing welding arcs between the welding torch and a work piece; and control circuitry configured to: detect a first set of signals relating to a first pulsed electrical current supplied to the welding torch by the base unit; store in memory a first pulsed power waveform based on the first set of signals; detect a second set of signals relating to a second pulsed electrical current supplied to the welding torch by the base unit; compare a second pulsed power waveform based on the second set of signals with the first pulsed power waveform; quantify a difference between the first pulsed power waveform and the second pulsed power waveform; and determine an extension of the electrode relating to the second pulsed power waveform based at least in part on the difference.
