Abstract: A method and apparatus for welding is disclosed. The output is preferably a cyclical CV MIG output, and each cycle is divided into segments. An output parameter is sampled a plurality of times within one or more of the segments. The CV output is controlled within the (at least one segment in response to the sampling. The parameter is output power, a resistance of the load, an output current, an output voltage, or functions thereof in various embodiments. The control loop is preferably a PI or PID loop. The loop may be applied only within a window. The set point may be taught or fixed. The system can be used to weld with a controlled arc length.
Abstract translation: 公开了一种用于焊接的方法和装置。 输出优选为循环CV MIG输出，并且每个周期被分成段。 在一个或多个段内对输出参数进行多次采样。 CV输出控制在（至少一个段内，响应于采样），在各种实施例中，参数是输出功率，负载电阻，输出电流，输出电压或其功能，控制回路优选为 PI或PID回路，回路可以仅在窗口内施加，设定点可以被教导或固定，该系统可用于以可控制的弧长焊接。

IPC: B23K26/21
CPC classification number: B23K26/21
Abstract: Systems and methods for laser welding are disclosed. A laser welding system includes a manually operated laser welding torch to direct laser power to a workpiece to generate a puddle during a laser welding operation. The welding system includes a controller to regulate activation and regulation of the laser power based on user inputs, sensor inputs, and/or synergic control of a laser power source.

Abstract: A method and apparatus for starting a wire fed weld operation includes monitoring at least one of a prior run-in time, a prior run in distance, a prior run in wire feed speed, and/or whether or not there is contact at the time of a prior start. Then the wire position is controlled for a present weld operation in response to the monitored data.
