Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a device for thermal cycle testing of high-energy beam composite welding. Background technique [0002] High-energy beam hybrid welding has the characteristics of high energy density and fast welding speed, coupled with the fast heat transfer speed of aluminum alloy, which greatly affects the forming accuracy of parts. Accurate measurement of transient temperature field is the premise and basis for controlling deformation. [0003] Currently developed welding thermal cycle test technology is mostly aimed at slow TIG and MIG welding processes of metal materials with small thermal diffusivity, and the test hardware and software system are separated, so they cannot be well integrated, providing real-time dynamic data collection, display and post-processing. Disposal creates difficulties and it is difficult to form a commercial product. Contents of the inventi...
