Abstract

The invention discloses a method for repairing cracks on the surface of key parts of a chain grate and relates to the technical field of machinery manufacture and material processing and application. The method comprises the following steps: firstly, according to the condition of cracks on the surface of the key parts of the chain grate, the cracks are polished and cut to remove the cracks completely, then laser cladding is carried out on the crack area by laser cladding technology, and laser-shock processing is carried out on the key parts of the chain grate after the laser cladding repair. The method has the advantages of simple process method, no need of vacuum and preheating, small damage to the base material of the key parts of the chain grate, realizing non-destructive repair of the cracks on the surface of the key parts of the chain grate and reducing the repair cost.

Description

technical field

[0001] The invention relates to the technical field of mechanical manufacturing and material processing and processing applications, in particular to a method for repairing surface cracks of key components of a chain grate, and is especially suitable for repairing surface cracks of large-area and thick materials of key parts. Background technique

[0002] In advanced manufacturing technology, laser shock processing technology, as a typical representative of high-energy beam, is a processing method with good prospects. Its principle is that the shock wave induced by high-energy short-pulse laser interacts with the material. The high-pressure shock waves generated are used to improve the mechanical properties of materials, especially crack fatigue life. This technology has been widely used in mechanical engineering, shipbuilding, aviation, microelectronics and other industries.

[0003] Laser cladding, also known as laser cladding or laser cladding, is an impo...
