The causes of cracksDuring the fusion process, the high-energy laser beam rapidly heats up, causing a significant temperature gradient between the fusion layer and the substrate. In the subsequent cooling, the volume of the cladding layer and the substrate is inconsistent, which constrains each other and generates stress.During the growth process ...

Laser cladding is a welding process that uses a focused laser beam to produce a molten pool on the surface of the part. The metal feed is injected into the molten pool at the same time to completely melt and form deposits. The feed is usually metal powder, but it can also be metal wire. The key to the success of laser cladding is to control the hea...

At present, damage identification and location in remanufacturing is an artificial vision task. It takes time and effort. And may lead to inaccurate repair. In order to alleviate this problem, this paper proposes a vision based automatic damage location method, which integrates the camera into the robot laser cladding repair unit. Two case studies ...
