Daokedao Laser Cladding: Solving the Problem of Traditional Welding Shaft Cracks
Date:2025-11-03 14:41     Source:daokedao     Browse:51

When traditional welding is used to repair shaft parts, a large amount of heat input leads to concentrated welding stress, and the shaft body is prone to new cracks, especially for alloy material shafts, with a crack occurrence rate of over 30% and a low success rate of repair.

The Daokedao laser cladding equipment adopts low stress cladding technology, with a heat input of only 1/6 of the weld deposit, and a very small heat affected zone, effectively avoiding the occurrence of welding cracks. The equipment is equipped with an online crack monitoring system, which can detect the repair process in real time and ensure the quality of the repair.

For alloy shaft parts such as 40Cr and 35CrMo, the repair success rate of Daokedao equipment is 99%, and there are no new cracks in the repaired shaft body, and the strength is restored to over 95% of the original strength. In industries such as wind power and machine tools, this technology has successfully repaired multiple large shaft equipment, recovering significant economic losses for enterprises.
