提出了一种新型的焊丝熔化极气体保护焊（GMAW）方法。熔滴过渡对焊接过程有重要影响，通过对熔滴受力情况的分析，阐明了焊接过程中熔滴过渡现象。分析了电弧压力、旋转力和焊接工艺参数对熔滴过渡的影响。作为焊接过程的一部分，CWW的特殊结构影响金属过渡期间的电弧特性和力。分析了熔滴形成过程中各细焊丝的熔滴、电弧、电磁力对熔滴形成的影响及其耦合过程。电弧压力和旋转力有利于熔滴过渡，提高熔滴过渡频率。熔滴尺寸随焊接参数的增加而减小。
A cable-type welding wire (CWW) gas metal arc welding (GMAW) method was proposed as a novel approach, using CWW for the consumable electrode. Droplet transfer influences the welding process, and the forces on the droplet were analyzed to elucidate the metal transfer phenomenon observed during the welding process. The effects of the arc pressure, rotating force, and welding parameters were analyzed to understand the metal transfer. The special structure of the CWW affected the arc characteristics and forces during metal transfer as part of the welding process. The droplet formed by droplets from each thin wire, the arc, and electromagnetic forces on droplet formation and the coupling process were analyzed. The arc pressure and rotating forces are beneficial to metal transfer and increase the droplet transfer frequency. The droplet size decreases with increasing welding parameters.
