Embodiment 1

[0027] A method for preparing a multi-component aluminum alloy welding wire, the specific steps are as follows:

[0028] Step 1. According to the configuration requirements of the wire material composition, select aluminum alloy wires of different compositions and diameters, clean the surface and dry them. In this embodiment, one ER2319 aluminum welding wire with a diameter of 3.0 mm and one ER5356 aluminum welding wire with a diameter of 2.0 mm were selected, cleaned with absolute ethanol, and air-dried.

[0029] Step 2. Threading the mold. Place the above two aluminum alloy welding wires of different diameters in parallel to form a bundle, pass through the forming hole from the outlet end of the mold, and connect with the aluminum alloy welding wire bundle, and prepare for passing the aluminum alloy welding wire through the mold. . As shown in the figure, the selected mold is a tungsten steel round hole mold for steel wire drawing, the hole diameter of the forming section i...

Abstract

The invention relates to a multi-component aluminum alloy welding wire and a preparation method thereof, wherein the aluminum alloy wire is formed by extruding and drawing two or more aluminum alloy wires, and the proportion of the aluminum alloy wires is calculated and prepared according to the required proportion of the final formed aluminum alloy wires. The aluminum alloy wire is preferably a binary or ternary alloy. The aluminum alloy wires with different components are placed into bundles in parallel, and the aluminum alloy wires are heated and extruded and drawn to form to a specified diameter. According to the method, the components of the multi-component aluminum alloy wires can be adjusted as required, the method is simple and reliable, the production modes of multiple varieties and small batches are facilitated, the aluminum alloy welding wires with different components can be produced at lower cost, and the production is more flexible.

Description

technical field [0001] The invention relates to an aluminum alloy welding wire and a preparation method thereof. Background technique [0002] Aluminum alloys are widely used in aerospace, automobile, military and other fields due to their light weight, excellent mechanical and corrosion resistance properties, especially the representative multi-element alloy systems, such as 2xxx, 7xxx series (Al-Cu-Mg, Al- Zn-Cu-Mg) etc. However, the welding of aluminum alloys with multi-alloy systems is prone to segregation cracks, etc., which has been plagued by its application. [0003] The primary problem for welding aluminum alloys in multi-alloy systems is the selection of welding wires. At present, most aluminum alloy welding wires are binary alloy system welding wires such as Al-Si, Al-Mg, Al-Cu, and less are ternary and above alloy system welding wires; and the cost of developing multi-component system welding wires is also high. At the same time, for the welding of aluminum al...
