Abstract

The invention discloses a flux-cored welding wire with high ductility, which comprises a welding wire and an extension head. The extension head is arranged on the right side of the welding wire, and the extension head is nested in the welding wire. This kind of high-ductility flux-cored welding wire is equipped with extension strips, filling layers, split layers and shrinkage layers. The extension strips are made of welding materials with good ductility, and the volume shrinks during the stretching process. The radius is reduced. At this time, it can be well combined with the filling layer so that the filling layer can quickly fill the vacancy of the extension strip and avoid the breakage of the extension strip. The filling layer can fill the vacancy of the extension strip in time and avoid the breakage of the extension strip. The split layer is used to divide the extension strip and the filling layer, so that the extension strip and the filling layer can fully cooperate to increase the ductility. The shrinkage layer is used to separate the filling layer and the connection layer, and has the function of shrinkage, so that the filling layer is close to the extension strip to make the filling The layer fully plays its role, and the combination of various structures greatly improves the ductility of the flux cored wire.

Description

technical field [0001] The invention relates to the technical field of flux-cored welding wire, in particular to a flux-cored welding wire with high ductility. Background technique [0002] Flux-cored welding wire is also called tubular welding wire or, by adjusting the type and proportion of the alloy composition of the powder, it is very convenient to design various welding materials for different purposes (wear resistance, high strength, heat resistance, corrosion resistance, low temperature resistance, etc.), Because its alloy composition can be adjusted flexibly and conveniently, many varieties of flux-cored wire cannot be smelted and rolled by solid wire. At the same time, due to the characteristics of product structure, welding process performance and welding efficiency of flux-cored wire are compared with solid wire. Manual welding rods are more advantageous. [0003] However, the existing flux-cored welding wire has a simple internal structure, so that the overall ...
