AI Technical Summary

Technical Problem

When manually welding the nickel wire mesh in an alkaline water hydrogen production electrolytic cell, the nickel wire mesh is prone to deformation, the welding quality is difficult to guarantee, and the welding torch is prone to puncturing the nickel wire mesh, making it difficult to adhere to the electrode plate and affecting the current flow.

Method used

The laser welding device includes a laser welding machine, a wire feeder, a rotating platform, an adjustable support, a laser welding gun, a wire feeding nozzle, and a mesh pressing mechanism. The laser welding gun melts the welding wire above the welding wire, and the welding wire drips onto the edge of the nickel wire mesh for welding. The mesh pressing mechanism ensures that the nickel wire mesh adheres to the electrode plate.

Benefits of technology

This method enables reliable welding of nickel wire mesh to the electrode plate, ensuring welding strength and flatness, preventing the nickel wire mesh from melting and breaking down, and improving welding quality and efficiency.

Abstract

This invention relates to a welding apparatus and method for nickel wire mesh in an alkaline water hydrogen production electrolytic cell. The apparatus includes a laser welding machine, a wire feeder, and a rotating platform, as well as an adjustable support, a laser welding torch, a wire feeding nozzle, a wire feeding tube, and a mesh pressing mechanism. The laser welding machine has a built-in laser welding torch, and the wire feeder has a built-in wire feeding tube and a wire feeding nozzle. The wire feeder contains welding wire, one end of which passes through the wire feeding tube and the wire feeding nozzle before extending out. The end of the welding wire is positioned above the edge of the nickel wire mesh but does not contact it. The adjustable support houses the laser welding torch, and a connecting ring is provided between the laser welding torch and the wire feeding nozzle. The end of the laser welding torch is positioned above the welding wire, and the focal center of the laser beam emitted from the end of the laser welding torch is located on the welding wire. The adjustable support can also be adjusted to connect a mesh pressing mechanism for pressing the edge of the nickel wire mesh. This invention arranges the welding wire above the edge of the nickel wire mesh, and the welding wire melts and drips onto the edge of the nickel wire mesh when heated, facilitating welding without melting the nickel wire mesh.
