Abstract
The utility model relates to the technical field of welding wires, in particular to a novel double-layered flux-cored wire. The novel double-layered flux-cored wire comprises a flux-cored layer I, an inner sheath, a flux-cored layer II and an outer sheath, wherein the inner sheath is arranged outside the flux-cored layer I; the outer sheath is arranged outside the inner sheath; the flux-cored layer II is arranged between the inner sheath and the outer sheath; 3-8 fixing strips are arranged on the inner sheath in the circumferential direction; a moisture absorption layer is arranged on the outer sheath; the inner sheath and the outer sheath are both made of metal strips; the moisture absorption layer is made from titanium composite oxide. According to the utility model, the flux-cored wire is designed into two layers, and the fixing strips are arranged on the inner sheath, so that the consumption and adsorption force of the core powder are increased, the metallurgical reaction and the protective effect of the core powder are more full, and accordingly, the metallurgical performance and the arc stability of the flux-cored wire are greatly enhanced; as the titanium composite oxide moisture absorption layer is arranged on the outer sheath, the wire is free from moisture, and accordingly, the gas pore prevention performance and the operation performance of the flux-cored wire are improved.
Description
Technical field
The utility model relates to the technical field of welding wire, especially a kind of novel double-layer flux-cored wire.
Background technology
Welding material is " iron and steel needlework "; the raising of manufacturing industry level be unable to do without the progress of welding material; replace gradually at present inefficient, highly energy-consuming and high pollution the flux-cored wire of stick electrode; in the process using; owing to mostly adopting individual layer welding wire; because metallurgical reaction and the protective effect of medicine core powder can not be abundant, deposited metal is hydrogeneous, nitrogen content will reduce, and greatly reduces use and the operating characteristics of flux-cored wire.
Utility model content
In order to overcome the deficiency of existing technology, the utility model provides a kind of novel double-layer flux-cored wire.
The utility model solves the technical scheme that its technical problem adopts: a kind of novel double-layer flux-cored wire, comprise drug core layer one, endothelium, drug core layer two and crust, the outer endothelium that is provided with of described drug core layer one, described endothelium is provided with crust outward, between described endothelium and crust, be provided with drug core layer two, on described endothelium, be provided with 3-8 bar fixed strip along the circumferencial direction of endothelium, described crust is provided with moisture absorbing layer.
According to another embodiment of the present utility model, the material that further comprises described endothelium and crust is steel band.
According to another embodiment of the present utility model, the material that further comprises described moisture absorbing layer is titanium composite oxide.
The beneficial effects of the utility model are; flux-cored wire is designed to two-layer; and endothelium is provided with fixed strip; use amount and the absorption affinity of medicine core powder are increased; it will be more abundant making metallurgical reaction and the protective effect of medicine core powder, greatly increase metallurgical performance and the arc stability of flux-cored wire, and on crust, be provided with titanium composite oxide moisture absorbing layer; thereby welding wire can not be made moist, improved anti-pore ability and the operating characteristics of flux-cored wire.
