最近几年,等离子弧焊(PAW)和气体保护焊(GMAW)的复合焊系统逐渐发展起来,在低碳钢板以及钢管的连续焊接工艺中的应用可与埋弧焊(SAW)相媲美。它所焊接的焊缝形
In recent years, composite welding systems for plasma arc welding (PAW) and gas shielded welding (GMAW) have evolved to make it comparable to submerged arc welding (SAW) for continuous welding of mild steel and steel tubes. Welded seam shape
