摘要
简要分析WK-55型矿用电铲提升滚筒轴座根部贯通裂纹的分布状况及产生原因,详细论述现场检修轴座根部开裂焊缝过程中采用的钟点固定控制应力变形方法、焊接工艺以及焊后焊缝去应力热处理等内容。钟点固定控制应力变形措施首次应用在大型矿山设备的结构件焊缝开裂的现场检修作业中,为同行业的检修作业积累了宝贵的经验。
The article analyzes the distribution and causes of WK-55 shovel lifting roller shaft seat root penetration cracks,discusses the hour fixed control stress deformation method, welding technology and weld stress relief heat treatment in the welding process of field maintenance shaft seat root. The hour fixed control stress deformation method is applied on the spot overhaul of the structural parts welding seam of large mining equipment, which accumulates valuable experience for the same industry.
