全面介绍了钢轧辊局部缺陷修复的实用冷焊工艺。结合工程应用，分析了“分区孤立堆焊”、“周边熔合区最后形成”、“焊缝整体硬—软结合”等工艺要点，对降低焊接区内应力，提高焊缝工作寿命有独特作用。该工艺是近百条轧辊局部修复的实践总结，特别是在降低焊接内应力和保证熔合区质量方面的措施，对高硬度构件的堆焊工艺设计，有一定的参考价值。 A comprehensive introduction to the practical cold-rolling steel repair process of local defects. Combined with the engineering application, this paper analyzes the key points such as “isolated soldering in partitioning”, “the final formation of the peripheral fusion zone” and “the overall hard-soft joint of the weld”. It has the unique function of reducing the stress in the welding area and improving the service life of the weld. The process is a practical summary of nearly one hundred partial repairs of rolls, especially in the aspects of reducing the internal stress of welding and ensuring the quality of fusion zone. It is of certain reference value to the design of surfacing welding of high hardness components.
