电弧是弧焊工艺的核心能量载体,其动态行为与热力特性直接决定熔池形态及焊缝成形质量。作为电弧的输出来源,焊接电源输出特性关系到热输入均匀性,同时,波形控制精度则直接影响熔滴过渡过程与电弧形态调控效果。从弧焊工艺与电力电子技术的交叉视角出发,综述了电弧-电源耦合控制的研究进展,重点解析了弧源协同控制技术中电弧形态主动控制、熔滴过渡精确调控及多参数闭环反馈等核心突破。最后从焊接电源与电弧的协同控制技术方面进行了展望。
As the core energy carrier in arc welding processes
the dynamic behavior and thermal characteristics of the electric arc were found to directly determine molten pool morphology and weld formation quality. Serving as the output source of the arc
the output characteristics of welding power sources were demonstrated to govern heat input uniformity
while waveform control accuracy was proven to critically influence droplet transfer processes and arc morphology regulation effectiveness. In this study
a cross-disciplinary methodology integrating arc welding processes with power electronics technologies was adopted. Research progress in arc-power coupling control was systematically summarized
with particular emphasis on core breakthroughs in arc-source collaborative control mechanisms. Key innovations were analyzed
including active arc morphology control strategies
precision droplet transfer regulation methods
and multi-parameter closed-loop feedback architectures. Finally
future development trajectories were proposed regarding synergistic control technologies between welding power sources and electric arcs.
