During the laser cladding process, the interface between the cladding layer and the substrate generates an obvious temperature gradient due to heat accumulation and rapid cooling, which leads to problems such as tissue inhomogeneity and residual stresses. In order to improve the quality of the cladding layer, this paper innovatively adopts the electromagnetic-assisted laser induction heating cladding method, i.e., a transformable auxiliary laser induction heat source is applied on one side of the cladding zone, and the temperature compensation of the cladding low-temperature zone is carried out by utilizing the controllable heat input characteristics to achieve the uniformity control of the cladding layer temperature field. Combined with the establishment and experimental verification of the induction heating model of electromagnetic-assisted laser cladding, the dynamic evolution of the temperature field of electromagnetic-assisted laser cladding is systematically investigated to provide theoretical basis and technical support for the development of high-precision laser cladding process.

摘要

During the laser cladding process, the interface between the cladding layer and the substrate generates an obvious temperature gradient due to heat accumulation and rapid cooling, which leads to problems such as tissue inhomogeneity and residual stresses. In order to improve the quality of the cladding layer, this paper innovatively adopts the electromagnetic-assisted laser induction heating cladding method, i.e., a transformable auxiliary laser induction heat source is applied on one side of the cladding zone, and the temperature compensation of the cladding low-temperature zone is carried out by utilizing the controllable heat input characteristics to achieve the uniformity control of the cladding layer temperature field. Combined with the establishment and experimental verification of the induction heating model of electromagnetic-assisted laser cladding, the dynamic evolution of the temperature field of electromagnetic-assisted laser cladding is systematically investigated to provide theoretical basis and technical support for the development of high-precision laser cladding process.
