In the diamond tools’ manufacture, brazing is a welding method using silver solder slices to stick segments to the diamond tool’s body. It is a physical combination. It not only consumes expensive silver solder slices, but has other disadvantages, such as low welding speed and big welding deformation. More importantly, its welding toughness is not very high. When the temperature of the diamond tool’s working part rises to a high degree in the job, the welding positions will get looser, and the segments may even fall off and cause a safety problem.

Laser welding does not need silver solder slices. It uses the energy of the laser beam to melt the contact parts of segments and the diamond tool’s body, and then cause a metallurgy combination.

The application of laser welding in the diamond tools’ manufacture has below advantages:

The ratio of the depth and width of the weld is big.

The combination toughness is high, so the laser welded diamond tools can withstand high temperatures and big impacts without the segments’ falling off.

Laser welding is precise, so the affecting area of the welding heat is small, and then the deformation of the diamond tools is also small.

Laser welding is fast, so the production efficiency is high.
