1. Brazing quality problems, such as sand inclusions, micro-cracks and other defects in the welding place.

2. The size of the weld gap is not well controlled, and the amount of solder used in brazing is small, resulting in insufficient welding force, resulting in virtual welding, which affects the use effect.

3. The choice of solder. Commonly used brazing materials are copper and silver. Under normal circumstances, as long as the process is strict, the alloy head after welding with two types of solder can meet the production needs of picks, and the solder that does not meet the quality requirements will affect the brazing effect.

The picks produced by Wuxi Saimax use imported flux solder, and the transmission speed and welding temperature of the picks are precisely controlled by the computer to ensure that the welding of each pick alloy head is full and free of defects such as copper and bubbles, and at the same time make each pick The inside and outside of the tooth are fully heated to reach the required quenching temperature. The automatic manipulator puts each pick into the quenching pool. The raw material, concentration ratio and quenching time of the quenching liquid are the best solutions obtained by our company's technicians after long-term repeated tests.
