Machining process of 5183 aluminum alloy semi-finished welding wire

Abstract

The invention relates to a machining process of welding materials, in particular to a machining process of a 5183 aluminum alloy semi-finished welding wire. The machining process comprises the following steps that a wire rod for a raw material aluminum alloy welding wire is fed into a cold rolling mill for rolling through a pay-off rack and a wire rod tensioning mechanism, and the aluminum alloy semi-finished welding wire is obtained; and the welding wire is subjected to annealing treatment after being taken up by a take-up rack, and finally the welding wire is packed and put in storage. Compared with drawing methods, the defects that through drawing processes, lengths are limited, wire breaking and cracking are liable to occur, and pass deformation and total deformation between two timesof annealing are limited can be overcome, the machining process has the advantage of high production efficiency and the advantage of precise control over the welding wire diameter, the cost is moderate, application is convenient, the product quality of the aluminum alloy welding wire is ensured, the product rejection rate is lowered, energy consumption is reduced, the cost is reduced, the labor intensity of staff is relieved, and the potential safety accidents are reduced.

Description

technical field [0001] The invention relates to a processing technology of welding materials, in particular to a processing technology of 5183 aluminum alloy semi-finished welding wire. Background technique [0002] In the welding wire production process, it is necessary to turn the thicker welding wire into a semi-finished welding wire that meets the requirements for subsequent processing, and the prepared semi-finished welding wire is wound on the corresponding wire storage device for storage, and then the subsequent further drawing Pulling process. At present, the aluminum alloy welding wire produced in our country has serious quality instability problems, and the aluminum alloy welding wire for some purposes (especially high-speed trains) still relies on imports. The annual import volume of high-grade welding wire reaches 70%. [0003] The preparation of semi-finished welding wire is the first process of welding wire production, which is crucial to the quality of the f...
