Problems solved by technology

[0003] The existing welding wire has low structural strength and is prone to bending when subjected to external force, which makes it easy to deform during use and affect normal use. At the same time, the function of the welding wire is not perfect, and there is a certain inconvenience in use. At the same time, the welding wire at the center burns faster than the welding wire at the edge, which easily leads to uneven burning of the welding wire and affects normal use

Abstract

The invention discloses a central-wire-free stranded welding wire, and belongs to the technical field of welding wires. The central-wire-free stranded welding wire comprises a welding wire body, wherein the welding wire body is mainly composed of an inner sheath, a plurality of welding cores, an outer sheath and a shell; the welding core strands are wound on the outer surface of the inner sheath;and a conductive rod is arranged in the inner sheath. The inner sheath, the outer sheath, a reinforcing plate, the conductive rod, a conductive coating and an annular heat conduction groove are arranged, the reinforcing plate is used for supporting the inner sheath, and the welding cores are stranded and wound on the outer surface of the inner sheath, so that a central-wire-free effect is achieved, and the welding wire body can be uniformly combusted during combustion. Meanwhile, the conductive rod and the conductive coating are arranged, so that the welding wire body has good electric conduction performance. It is ensured that heat can be quickly dissipated when the welding wire body is combusted through the arrangement of the annular heat conduction groove, the contact area between air and the welding wire body can be improved, and the combustion efficiency is improved.

Description

technical field [0001] The invention belongs to the field of welding wire technology, and in particular relates to a stranded welding wire without a central wire. Background technique [0002] Welding wire is used as a filler metal or as a wire welding material for electrical conductivity. In gas welding and gas tungsten shielded arc welding, the welding wire is used as filler metal; in submerged arc welding, electroslag welding and other gas shielded arc welding, the welding wire is not only the filler metal, but also the conductive electrode, and the surface of the welding wire is not Apply anti-oxidation flux, and the warehouse where the welding wire is stored should have a dry and ventilated environment to avoid moisture; reject water, acid, alkali and other liquids that are highly volatile and corrosive, and it is not suitable to coexist with these substances in the same warehouse. [0003] The existing welding wire has low structural strength, and it is easy to bend w...
