Abstract

The invention relates to a laser multi-beam compound temperature field welding device. The device at least comprises a deep penetration welding laser head, a preheating laser head, a slow cooling laser head and an infrared temperature field measuring device, wherein the deep penetration welding laser head is arranged on a spindle and used for emitting main welding laser beam for fusion welding onwelding parts; the preheating laser head is used for emitting preheating laser beam in the fusion welding process of the welding parts and is adjustably arranged on the periphery of the spindle through the position of a first movement mechanism; the slow cooling laser head is used for emitting slow cooling laser beam in the fusion welding process of the welding parts and is adjustably arranged onthe periphery of the spindle through the position of a second movement mechanism; the infrared temperature field measuring device is arranged in a preset range of the deep penetration welding laser head, and used for measuring the temperature in a compound temperature field formed by the main welding laser beam, the preheating laser beam and the slow cooling laser beam through fusion welding during welding in real time.

Description

technical field [0001] The invention relates to the technical field of laser beam processing, in particular to a laser multi-beam composite temperature field welding device. Background technique [0002] Due to its high energy density, small welding deformation, easy integration, automation and flexibility of the welding process, high-precision and high-efficiency welding, laser welding technology has been widely used in aviation, aerospace, automobiles and other fields in recent years. [0003] At present, laser single-beam welding and laser double-beam welding technologies have been developed and matured, and have been successfully applied in the welding process of thin-walled structural parts such as aviation, aerospace, ships, and high-speed rail. Laser single-beam welding mainly solves the problem of splicing components of conventional thin-walled materials. This technology is highly mature, but it does not have the functions of preheating and slow cooling. It is genera...
