    摘要： A heating current used to inductively heat a metallic or magnetic work-piece is generated by an inverter supplied by a supply voltage. The inverter includes four switching elements arranged in an H-bridge circuit having two parallel longitudinal branches and a transverse branch. The switches are controlled so the heating current flows through the transverse branch. The diagonally opposed switching elements are switched from a conductive to a non-conductive state in a temporally staggered manner.

    摘要： A process and a system are proposed for short-time arc welding, in particular for stud welding, with the step of sampling a welding parameter, in particular the arc voltage (U), during at least one time segment (Ts) of the welding operation, in order to detect disturbances, wherein the measurement curve determined from the sampling operation is smoothed and subsequently wherein at least one tolerance curve is generated which lies at a previously adjustable distance from the smoothed measurement curve, and subsequently the unsmoothed measurement curve is compared with the tolerance curve in order to detect high-frequency disturbances.
