相比其他窄间隙焊接技术,窄间隙气体保护焊具有更高的综合技术优势和性价比,目前应用率不高的根本原因在于相关关键技术的完全突破和技术完全配套状况。论述窄间隙气体保护焊的相关关键技术,主要包括:两侧壁熔合控制技术、实现六大功能要求的焊枪设计与制造技术、焊缝轨迹自适应跟踪技术、焊接高温区高效气体保护技术和超低飞溅率弧焊电源技术,并分析各关键技术的最新技术进展。
Compared to other narrow gap welding technology, narrow gap gas shielded welding has a higher overall technical advantages and cost-effective, the current low utilization rate of the fundamental reason is the complete breakthrough of the relevant key technologies and technology fully supporting the situation. The key technologies of narrow gap gas shielded welding are discussed, including the welding control technology of the two side walls, the design and manufacture of welding torch to achieve the six major functions, adaptive tracking of weld trajectory, high-efficiency gas protection technology in welding high temperature area, Low-spatter arc welding power technology, and analysis of the latest technology advances in key technologies.
