| Abstract: | This paper aimed to deeply investigate the domestic and abroad status and trend for the laser welding technology and equipment of diamond core drill bit.On the basis of the characteristics of diamond core drill bit structure and its welding technology,three kinds of laser welding equipment were analyzed synthetically for German Dr.fritsch co.,Korea Diex co.,and self-developed laser welding system,including their feeding and clamping and welding methods between steel body and dia- mond segment.Then the paper briefly introduced the gas laser source widely used in the world as slab CO_2 laser,fast-flow CO_2 laser,traverse-flow CO_2 laser and their compatibility with laser welding system. |
