What are the welding skills of diamond bit?

  • Author:Dora Zhang
  • Release on:2022-07-15
When the diamond bit is welded, the bit is welded flat on the base tooth of the saw blade, and the quality of the bit affects the sawing efficiency and the service life of the base.

Saw blade segment for stone edge cutting, can be suitable for cutting stone slabs, 900-3500mm diamond segment is suitable for cutting blocks and mines.

The welding cutter head shall be able to adjust the cutter head around and radially to ensure the welding accuracy requirements of the end face symmetry and circumferential symmetry of the cutter head relative to the substrate.

U slot diamond cutting segment adopts high-frequency welding to quickly heat the connecting teeth of the saw blade matrix, which speeds up the welding speed and is not easy to remove the teeth.

2. Adopt high-frequency welding, select high-quality silver welding pieces, and strictly control the temperature and heating time during welding, so as to avoid the problems that the induction area of each tooth is too large and connected due to heating for too long or welding at too high temperature, resulting in abnormal deformation of the piece body and making the piece body unusable.

High frequency induction heating welding machine,uses a series resonant circuit , the resonant output low voltage , high current frequency power by high-frequency transformer.

3. Precautions for welding of cutter head: in order to reduce the deformation of the substrate in the normal welding process and improve the service life of the substrate, please use the spacer welding or diagonal welding process.

4. After welding, remove it, hang the saw blade vertically, and cool the air naturally. Do not use quenching methods (such as direct blowing with compressed air or cooling the sawtooth after welding with water, which will cause sawtooth falling off and affect the use). Generally, it is appropriate to hang it for more than 10 hours after welding, and put it into use.
