Welding of the diamond saw blade
After you check the blanks according to the specifications, you can select the appropriate tooth for welding (requirements: tooth width ≥1.27 times the thickness of the blanks) before welding, and then the blanks should be cleaned. The following points should be paid attention to when welding:
1). Select the correct diamond segments which matches the object to be cut, and weld them on the blanks tooth Straightly. The cutting efficiency and the lifespan of the blanks are affected by the quality of the diamond segments.
2). The welding instruments should be able to adjust in axial direction and in the radial direction accordingly, in order to ensure the welding accuracy requirements, such as axial symmetry, radial symmetry.
3). It will be much better to use high frequency welding generator. Meanwhile, select the appropriate silver solder and silver content is not less than 35% . In the welding process, the temperature and time are strictly controlled, and the welding temperature is generally controlled between 600 ° C and 800 ° C. In the welding process, it is necessary to avoid the connection of tooth induction zone caused by too long heating or too high temperature welding, which will cause abnormal deformation of the blank and make the blank unable to use.
4). In order to reduce the deformation of the blanks in the normal welding process and improve
5). The blade should be cooling off in the natural more than 2 hours after welding, and then the saw blade should be hung up in vertically by the centre holes, then cooling in the nature. Do not use flash cooling method (such as blowing with Compressed air directly or water-cooling the saw tooth area after welding, which may cause saw tooth drop and other phenomena to affect the use) . Generally, it should be hung for more than 10 hours after welding.
6). The flatness of the saw blade and the side runout and tension should be checked before used. If saw blade need to be repaired after welding saw blade or after inspection, please contact the professionals.
