高速钢带柄刀具常用预热闪光对接焊(通称为“对焊”),把高速钢和结构钢焊接起来。由于对焊存在很多人为的因素,缺陷又无法当即发现,事后纠正也颇费精力,往往造成较大的损失。因此,对刀具对焊缺陷进行分析,防患于未然,在生产中有一定的意义。以下仅就我们在生产中的体会作一简述。 High speed steel shank tools are commonly used for preheating flash butt welding (commonly known as “butt welding”) to weld high speed steel to structural steel. Because there are many artificial factors butt welding, defects can not be found immediately, after rectification is also a lot of energy, often resulting in greater losses. Therefore, the analysis of tool welding defects, take preventive measures, in the production of a certain significance. The following is a brief summary of our experience in production.
