对预涂底漆钢板ＣＯ２气体保护焊焊缝进行了测氢试验、气孔产生倾向试验；分析了焊道表面气孔的性质和焊接工艺参数对气孔产生倾向的影响，并在此基础上提出了减少和防止产生气孔的措施。
Hydrogen test and blowhole propensity test of CO2 gas shielded welding seam of precoated steel were carried out. The influence of the stomatal property on the surface of weld bead and the welding process parameters on the stomatal tendency were analyzed. Based on this, And to prevent the production of stomatal measures.
