Problems solved by technology

However, in actual laser welding, there are many factors that affect the stability of the focus position, including the change of the welding nozzle-workpiece distance caused by non-planar workpieces and welding deformation, the change of the focus position caused by the thermal lens effect of laser windows, focusing mirrors and other components, And the change of the focus position caused by the different positions of the beam in the flight optical path, etc.

Description

technical field [0001] The invention relates to a laser welding device, in particular to a laser welding device carrying multiple sensors. Background technique [0002] Laser welding is one of the important aspects of the application of laser material processing technology. It is also often called laser welding machine and laser welding machine. According to its working mode, it can be divided into laser mold welding machine (manual welding machine), automatic laser welding machine, Laser spot welding machine, optical fiber transmission laser welding machine, optical welding is to use high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation diffuses to the inside of the material through heat conduction, and the material is melted to form a specific molten pool. In order to achieve the purpose of welding. Laser welding process monitoring and quality control have always been an important part of the research and development in the f...
