Volvo机体修复工艺的探索实践与推广

介绍了综合运用以冷焊技术为主的多项铸铁修复技术，对一台报废Volvo机体进行缺损部位修复，使其得以重新利用。修理工艺主要涉及清理、焊补、镗修、检测等四部分内容。通过对修复过程进行总结分析，摸索出了以铸铁冷焊为主的多项修复技术在机体修复过程中的应用方法，并且总结出利用普通卧式镗床装夹数控刀具镗修缸孔的工艺过程，为今后修复此类铸铁类大型零件关键部位缺陷提供了一套切实可行的工艺方案。

Repairing Technique of Volvo Engine in Practice and Generalization

This paper introduces how to use some repairing techniques based on cold welding to repair a rejected Volvo engine.The technique mainly includes four parts: clearing,welding,boring and inspection.By analysis,a technique process by using general horizontal boring machine to hold CNC cutter to bore cylinder hole is summarized,which supplies a set of practical program for repairing same components.
