前言为节约高速钢并提高刀具柄部的韧性,带柄刀具一般都由两种不同金属组成——刃部用高速钢(W18、W9、W6……),柄部用碳结钢(45~#、40Cr……)。到目前为止,国内大多数工具制造厂采用予热闪光焊把毛坯的刃部和柄部焊接起来。我厂从1976年以来,采用摩擦焊新工艺代替闪光焊焊接刀具毛坯。两年来共焊接各种刀具毛坯60余万件。实践表明,和闪光焊相比,摩擦焊具有产品质量高而稳定,节约金属材 Preface To save high-speed steel and improve the toughness of the tool shank, shank tools are generally made of two different metals - high-speed steel for the blade (W18, W9, W6 ...) #, 40Cr ...). So far, most of the domestic tooling factories use flash-to-flash welding to weld the edges and shanks of blanks. I plant from 1976, the use of friction welding instead of flash welding new technology welding tool blank. Over the past two years a total of welding more than 60 million pieces of various tool blanks. Practice shows that, compared with the flash welding, friction welding with high product quality and stability, saving metal
