摘要

Pulse current metal flux-cored welding is a promising technique that provides benefits such as better process control and reduced spatter, leading to higher weld quality. However, optimizing this welding method requires addressing several complex challenges. This research presents the results of an experimental investigation based on flux-cored welding wire with the same average current but different pulse parameters. It has been shown that pulse current emerged as the primary influencer, significantly affecting weld quality and penetration depth, followed by duty cycle, frequency, and pause current. Optimal pulse-arc welding modes were proposed to meet specified penetration depth ranges, validated through verification experiments. To this end, the paper examines the application scope of flux-cored wires and highlights the necessity for such considerations. This work contributes to understanding of the factors affecting weld quality and sets the algorithm for optimizing pulse current modes for flux-cored wire welding applications.
