Abstract

The invention relates to multi-stranded welding wires, comprising solidwires and flux-cored wires; stranded solidwires and flux-cored wires are twisted and stranded to form an integral part or multistrand flux-cored wires are twisted to form an integral part; wherein, welding wires positioned in the center are called core wires; the other welding wires twisted around the core wires in the center are called peripheral wires. The invention resolves the defects of the traditional flux-cored wires such as small diameter, difficult swirling when the diameter of the traditional flux-cored wires is increased, poor rigidity and the like; the diameter of the stranded flux-cored wires has a wide variation range, thus obtaining larger weld depth, weld width or wider deposited layer which are in favor of the welding of large scale metal construction. Stranded flux-cored wires feature deep weld depth, large weld width, high deposition efficiency, simple process, high efficiency, strong swirling and good rigidity, thus being capable of obtaining larger weld depth, weld width or wider deposited layer and has a larger application range.

Description

A kind of multi-strand stranded welding wire
Technical field
The present invention relates to a kind of welding wire, be particularly useful for fusion penetration, molten roomy metal solder or surface overlaying.
Background technology
Flux-cored wire appears at the U.S. beginning of the seventies, in the last thirty years no matter be that output or kind all are tending towards continuous development, be widely used in fields such as metallurgy, steel construction, highway, railway, bridge, have that good, the easy fusion gold of adaptability, deposition rate height, fusion penetration are big, a good manufacturability, advantage that mechanical property is good.(mostly be 1.2mm~6.0mm), be not easy to the welding of large-scale hardware, if the diameter of traditional flux-cored wire is further increased, then its coiling property, outspoken nature variation are difficult to guarantee welding quality but traditional flux-cored wire diameter is less.
Summary of the invention
The objective of the invention is to overcome the weak point in the prior art, provide a kind of production technology simple, coiling property is strong, and outspoken nature is good, can obtain the welding wire of bigger fusion penetration, molten wide strands.
Multi-strand stranded welding wire of the present invention, comprise solid core welding wire and flux-cored wire, multiply solid core welding wire and flux-cored wire mixing hinge joint are one, or multiply flux-cored wire hinge joint is one, wherein: in the middle of a root bead silk is positioned at, be called core wire, all the other welding wires are stranded around middle core wire, are called peripheral silk.
Described hinge joint is that the stranded electrode of one is the prime number thigh; The chemical composition of described solid core welding wire or flux-cored wire is identical or different; The diameter of described solid core welding wire and flux-cored wire is identical or inequality.
Beneficial effect: it is big inadequately that the present invention has overcome traditional medicine core gage of wire, when increasing, diameter is difficult for shortcomings such as coiling, outspoken nature difference, stranded multiply flux-cored wire vary in diameter scope is big, can obtain bigger fusion penetration, molten wide and generous overlay cladding, help the welding of large-scale hardware, strands flux-cored wire fusion penetration is big, molten roomy, deposition efficiency is high, the welding or the surface overlaying of various large-scale metal structures of particularly suitable or part; Can be used for omnibearing stereo continuous welding work; Flux-cored wire or the solid core welding wire that can arrange in pairs or groups as required and contain heterogeneity are to obtain best welding or built-up welding effect.Its production technology is simple, the efficient height, and coiling property is strong, and outspoken nature is good, can obtain bigger fusion penetration, molten wide or generous overlay cladding, has wider range of application.
