COMPOSITE WELDING APPARATUS AND COMPOSITE WELDING METHOD

WIPO Patent Application WO/2018/107310

A1

Disclosed is a composite welding apparatus, comprising a welding power source, a welding gun (2), a laser (1) and a support system, wherein the laser irradiates a workpiece (7) at a welding spot produced by the welding gun, characterised in that the support system is further provided with a welding seam monitor (3) and a temperature measuring instrument (4), and a heat-radiating device (5) is connected to the support system. Disclosed is a composite welding method, comprising the following steps: step 1, after the laser (1) and the welding gun (2) cooperate to weld the workpiece (7), an infrared thermometer feeds back the temperature value at the weld to a computer, and the computer processes data and then forms a temperature field distribution map; step 2, after analysing temperature field data, determining the impact of the temperature in a molten pool on the welding seam quality, and if same has an impact, enabling the heat-radiating device, and specifically calculating the size of an air port of the heat-radiating device and the required heat-radiation position, and if same has no impact, directly proceeding to step 3; and step 3, an ultrasonic welding seam detector performing detection of the welding seam quality, and the computer feeding back welding seam information to operating personnel, so as to complete the entire welding process. The composite welding apparatus and the composite welding method detect the temperature field distribution of the molten pool in a timely manner, and perform timely temperature adjustment, wherein same can improve the quality of the welding seam, and timely detection of the quality of the welding seam by the welding seam monitor can reflect the quality of the welding seam in a timely manner.
