苏联车工丘吉科夫在一次鑽孔工作中,发现由于摩擦生热的结果,鑽头与工件焊在一起了。这种现象引起了他的注意,从而研究出来一种新的焊接力法——摩擦接触焊接法。 [摩擦接触焊的优缺点] 摩擦接触焊与电阻接触焊比较有下列优点:(1) 利用机械摩擦生热的方法代替了电阻加热,从而节约了大量的电能。(2) 焊件在焊前不需要任何准备,例如电阻焊的打锈磨光等。(3) 焊机的构造比较简单,其制造成本要比普通电阻
In the course of a drilling job, Soviet carmaker Jiukov discovered that the drill bit was welded with the workpiece as a result of frictional heat generation. This phenomenon caught his attention, which developed a new welding force method - friction welding. [The advantages and disadvantages of friction welding] friction welding contact resistance welding and resistance compared with the following advantages: (1) The use of mechanical friction heat generation instead of resistance heating, thus saving a lot of electricity. (2) Weldments do not need any preparation before welding, such as electric resistance welding rust polishing. (3) welding machine structure is relatively simple, the manufacturing cost than ordinary resistance
