摘　　要：ＢＨＷ３５钢电渣焊后经正火加亚温淬火和回火处理，其焊接接头及母材的冲击韧性大幅度提高，且强度也保持了较高的水平。The treatment of normalizing, sub-temperature quenching and tempering to W35 steel after electroslag welding can improve the impact toughness of the welding contacts and the mother steel, with the high strength being maitsined. The problem of low impact toughness of electroslag welding seam of BHW steel has been therefor resolved.

关 键 词：BHW35钢 淬火 冲击韧性 电渣焊 压力容器
