金属零件和毛坯历来都是用金属来修复的，在这种情况下，修复用材料与被修复表面的相互作用只能在金属结晶过程中才能得到保证。这样就不可避免地要求对被修复对象施加热作用。在采用这些零件修复方法时．必须使用适当的工艺装置并保证对这些工艺装置进行高技术水平的操作和保?
Metal parts and blanks have traditionally been repaired with metal, in which case the interaction of the repaired material with the repaired surface can only be guaranteed during metal crystallization. This inevitably requires the application of thermal effects on the object being repaired. When using these parts repair method. Must use the appropriate process equipment and ensure that these processes and equipment for high-tech operation and maintenance?
