Embodiment Construction

[0016] The technical solution of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0017] The method of the present invention adopts a magnesium alloy welding wire extrusion die with a porous working band. Based on the conventional magnesium alloy pipe extrusion splitter die, the working band between the upper and lower dies is designed to have an aperture size of 1 to 4 mm. Porous working belt, as shown in Figure 1. Figure 1 is a top view of a magnesium alloy welding wire extrusion die. The porous working belt 3 between the upper die 1 and the lower die 2 is composed of many holes, and the pore size is 1 to 4 mm.

[0018] The method of the present invention also uses a magnesium alloy welding wire drawing die corresponding to the shape and aperture of the porous working belt. The structure and shape of the drawing die is shown in Figure 2. The size and distribution of the small holes in the drawing die and the porou...

Abstract

A technology for producing (1-4)-mm welding Mg-alloy wire includes such steps as providing an extruding die with multi-hole working band, heating the Mg-alloy ingot, extruding die, extruding pad and the extruding barrel of horizontal extruder, sequentially putting said die, Mg-alloy ingot and extruding pad in extruding barrel, extruding at 10 m / min, cold drawing, coiling and packing.

Description

Technical field [0001] The invention relates to a production method of welding wire, in particular to an extrusion production method of magnesium alloy welding wire, and belongs to the technical field of material preparation. Background technique [0002] Magnesium alloy is currently the lightest metal structural material in industrial applications. Compared with other metal materials, it has the advantages of light weight, higher specific strength and stiffness, and good shock absorption performance. It also has much better recycling performance than engineering plastics. , Known as "21st Century Commercial Green and Ecological Metal Structure Materials". With the gradual increase in the amount of magnesium alloy products on the market, it is inevitable to involve the welding of magnesium alloy structural parts. [0003] At present, most of the welding wire used in the domestic magnesium alloy welding process is produced by the hot extrusion method, the diameter of the welding w...
