    摘要： A welding system and method provide for generating a controlled waveform for welding power output, the waveform comprising a plurality of successive peak phases followed by a short circuit between a welding wire electrode and an advancing weld puddle. Each then present peak phase is regulated based upon at least the immediately preceding short circuit to control the short circuit that will occur following the then present peak phase. Some embodiments permit regulating at least one waveform phase based upon at least the immediately preceding short circuit to control the next short circuit that will occur, and regulating at least one short response phase based upon at least the immediately preceding short circuit to control the next short circuit that will occur.

    摘要： A pulsed welding regime includes a peak phase in which energy is added to an electrode and a weld puddle, and a molten ball begins to detach from the electrode, followed by a dabbing phase in which current is significantly reduced to place the ball in the weld puddle with addition of little or no energy. The resulting short circuit clears and the system proceeds to a background phase. The current in the dabbing phase is lower than the current during the background phase. The process may be specifically adapted for particular welding wires, and may be particularly well suited for use with cored wires. The dabbing phase allows for lower energy to be transferred to the sheath of such wires, and resets the arc length after each pulse cycle.

    摘要翻译： 脉冲焊接状态包括峰值阶段，在该峰值阶段中，能量被添加到电极和焊接熔池，并且熔融球开始从电极分离，随后是其中电流显着减小以将焊球放置在焊接中的汲取阶段 增加很少或没有能量的水坑。 产生的短路清除，系统进入后台阶段。 冲击阶段的电流低于背景阶段的电流。 该过程可以特别适用于特定的焊丝，并且可以特别适合与芯线一起使用。 冲刷阶段允许较低的能量被传递到这些线的护套，并且在每个脉冲周期之后重置弧长。
