摘要： A method of and a system (100) for steering an arc and/or torch head (120) in a weld joint (145) is provided. The system (100) includes a torch head (120) that creates an arc in a weld groove formed in at least one workpiece (115A, 115B). The system (100) also includes a control unit (190) that includes a feedback system that monitors at least one of a voltage of the arc, a current of the arc, a power output of the torch power supply, and a contact tip to weld distance. The control unit (190) outputs a feedback signal corresponding to the monitoring. The control unit (190) also includes a comparison circuit that compares the feedback signal with at least one predetermined value corresponding to a position of at least one of the arc and the torch head (120) in the weld groove. The control unit (190) further includes an arc steering system (180) that outputs a steering signal based on the comparison.

摘要： An arc welding system includes a welding torch, an electrode, and a power supply having a switching-type power converter connected to the torch. A parallel state-based controller is connected to the power converter and provides a waveform control signal thereto for controlling its operations. The controller generates a motion control signal for controlling movements of the electrode and/or the torch. A sensor senses welding voltage or welding current. A memory stores a welding state table comprising sequential control states, and stores a motion control system state table comprising further sequential control states. The welding waveform is defined in the welding state table. The controller controls the operations of the power converter through the waveform control signal according to the welding state table, simultaneously adjusting the motion control signal according to the motion control system state table. The controller transitions between control states according to the signal received from the sensor.

摘要： An electric arc welder ( 100 ) and a method of performing a pulse welding process producing reduced spatter. The welder produces a current between an advancing electrode (E) and a workpiece (W). The welder includes a short - detecting capability for detecting a short condition upon occurrence of a short circuit between the advancing electrode and the workpiece. The welder may also include a switching module in the welding circuit path of the welder having an electrical switch and a resistive path. Times of occurrence of short intervals can be tracked and a blanking signal can be generated based on the tracked short intervals to anticipate a next short interval in a next pulse period of the pulsed welding process. The blanking signal can be used to reduce a welding current in the welding circuit path by introducing additional resistance into the welding circuit path via the switching module ( 110 ), or by controlling a portion of a waveform of the welding process during the blanking interval.
