What is Laser cladding?
Laser cladding refers to placing the selected coating material on the surface of the clad substrate by different feeding methods. After laser irradiation, it melts with a thin layer on the substrate surface at the same time, and forms a very low dilution after rapid solidification. The laser cladding machine assembled by howwell has stable performance.
The surface coating combined with the substrate metallurgically can significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical characteristics of the base surface, so as to achieve the purpose of surface modification or repair, which not only meets the requirements for the specific properties of the material surface, but also saves a lot of precious elements.

Laser cladding characteristic
Compared with surfacing, spraying, electroplating and vapor deposition, laser cladding has the characteristics of small dilution, dense structure, good combination between coating and substrate, many suitable cladding materials and large changes in particle size and content. Therefore, the application prospect of laser cladding technology is very broad. Howweld team believes that laser cladding brings a good way to repair the mold and re realize its own value to the product.
Synchronous laser cladding is to send the cladding material directly into the laser beam to complete the feeding and cladding at the same time. Cladding materials are mainly fed in the form of powder, and some also use wire or plate for synchronous feeding.
The main process flow of preset laser cladding is: substrate cladding surface pretreatment - preset cladding material - preheating - Laser Melting - post heat treatment.
The main process flow of synchronous laser cladding is: substrate cladding surface pretreatment - feeding laser melting - post heat treatment.
