Manufacturing process of welding wire for welding process

Abstract

The invention discloses a manufacturing process of a welding wire for a welding process. The manufacturing process comprises the following steps that (1) the following ingredients including 18 parts of Zr, 20 parts of Nb, 5 parts of C, 6 parts of Mn, 7 parts of Si, 8 parts of B, 2 parts of V, 3 parts of Ni, 4.5 parts of Cu, 1.5 parts of Cr, 0.05 part of S, 0.12 part of P and 15 parts of Fe are proportioned in parts by weight; (2) all ingredients are proportioned according to the corresponding weight parts, and are then melted and smelted in a metal smelting furnace, a welding wire mold is used, and the required welding wire is prepared. The manufacturing process of the welding wire for the welding process can overcome the defects of unreasonable proportion, poor stability, weak bearing force and the like in the prior art for realizing the advantages of reasonable proportion, good stability and strong bearing force.

Description

technical field [0001] The invention relates to the technical field of welding technology in mechanical engineering, in particular to a manufacturing process of welding wire for welding technology. Background technique [0002] Welding, also known as welding or welding, is a manufacturing process and technology that uses heat, high temperature or high pressure to join metal or other thermoplastic materials such as plastics. [0003] There are many sources of energy for welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. In addition to its use in factories, welding can also be performed in a variety of environments, such as in the field, underwater and in space. Welding, wherever it occurs, can pose a hazard to the operator, so proper precautions must be taken when welding. Possible injuries caused by welding to the human body include burns, electric shock, visual impairment, inhalation of toxic gases, and excessive ultraviolet ra...

AI Technical Summary

Problems solved by technology

[0004] However, the current welding wire has low plasticity and toughness of the weld, which increases the crack sensitivity of the welded structure and reduces the bearing capacity.

[0005] In the process of realizing the present invention, the inventors found that there are at least defects such as unreasonable proportioning, poor stability and weak bearing capacity in the prior art.
