The large welding current caused the formation of quenched martensite and the high residual stresses in the welding zone, resulting in the increase of zinc sensitivity of hydrogen attack. 结果表明:由于焊接电流过大,使焊缝产生淬火马氏体组织及较大的焊接残余应力,导致镀锌氢脆敏感性增加,造成吸油盘发生氢脆开裂。
Hydrogen can cause hydrogen attack to the steel material while CO2 can lead to the corrosion and spitting corrosion of the process equipment. 氢气可以使金属材料产生氢损伤,二氧化碳水溶液可引起设备产生全面腐蚀和点蚀。
