Description

technical field [0001] The invention belongs to the technical field of metal material processing, and in particular relates to a metal resistance heating device coupled with laser processing. Background technique [0002] As one of the important processes in mechanical manufacturing, the heat treatment of metal materials can endow or improve the mechanical, physical, chemical and other performance of the workpiece. At present, the heating methods used for heat treatment of metal materials mainly include radiation heating, induction heating and resistance heating. Traditional radiation heating increases the cost due to the need for a strict insulation layer, and the heating efficiency is low, and the cost of the ultra-high temperature (>1000°C) heating device rises sharply; of danger. Induction heating equipment is generally more complicated, the cost is relatively high, and the interchangeability and adaptability of the induction parts are poor. It is not suitable for w...

Problems solved by technology

[0003] Usually, the heat treatment process can only control the temperature parameters such as the heating temperature, heating rate, and holding time of the workpiece, and the bottleneck of process improvement and innovation is obvious; at the same time, for metal materials containing the second phase, the means of regulating the precipitated phase through heat treatment are also very limited.
