摩擦焊接是一种新的焊接方法.它是根据金属摩擦生熟,金属塑性增加的原理进行焊接的.摩擦焊接不仅设备和操作简单,而且可以得到很高的焊接质量.同时成本低,效率高.这种焊接方法很适合在探矿机械修配工作中使用.为此,本刊特发表本文,供地质勘探机械动力部门的研究,试验和推广时参考. Friction welding is a new welding method. It is based on the principle of raw metal friction and metal plasticity. Friction welding is not only simple in equipment and operation, but also can obtain high welding quality. At the same time, it has low cost and high efficiency. This welding method is very suitable for use in prospecting machinery repair work. For this reason, this publication is published in this paper for the reference of the research, testing and promotion of the geological exploration machinery power sector.
