| Abstract: | A mechanism is put forward of laser dip soldering of steel and cemented carbides.The influence of structure and composition change of the welding seam on the quality ofwelding is discussed. This paper also Presents the state change of WC and Co in the laserwelding process and its effect on welding quality. The metallurgical welding result withoutstrap fissures is given. |
