Hydrogen can cause hydrogen attack to the steel material while co 2 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。
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。
