Latest Patents

Yuexin Gao holds a patent for a "Continuous welding method and device for hybrid welding, welded finished product, train body." This invention involves a unique method of performing hybrid welding on a groove of a welding piece by coupling a laser and a variable polarity arc. The method ensures that the defocusing distance of the laser is not less than the Rayleigh length of the laser. This approach effectively reduces the power density of the laser on the surface of the welding piece, decreases the height-width ratio of the weld seam, and increases the diameter of the welding melted pore. Consequently, it addresses the issue of weld porosity, enhancing welding stability and reliability while improving the mechanical properties of the weld seams.
