There are several methods of classification of flux-cored wire, Aluminium Welding Wire manufacturing methods such as by classification: protection by flux-cored wire welding gas classification: classification by the use of flux-cored wire: the composition of the powder flux cored wire classification.
(1) according to the different manufacturing methods, flux-cored wire can be divided into: a seam seamless flux cored wire and flux-cored two. Seamed flux-cored wire is a thin strip through the roll forming process into a groove, which roll into powder, then rolled into a tubular wire drawing, processing and manufacturing made of low carbon steel commonly used raw materials, finished surface rust wire surface treatment to the same time to have good wire feeding performance, so the surface. no slit flux-cored wire is pre-filled steel pipe forming a good powder, and then after plating, wire drawing, wire products to the diameter size.
(2) according to the different shielding gas welding, flux-cored wire can be divided into: gas shielded flux cored wire and self-protection in China, Japan, South Korea, flux-cored CO2 as a shielding gas is mostly , while the self-shielded flux cored wire used in the United States the ratio is relatively high, gas prices in Europe because of the protection the difference, flux-cored wire mainly mixed gas (Ar-CO2) protection.
(3) according to different purposes, can be divided into flux-cored wire: low carbon steel and 490MPa grade steel, high strength steel, heat-resistant steel, cold steel, is corrosion of steel, stainless steel, and hardfacing flux-cored wire surfacing due to flux-cored wire can adjust the internal medicine core formula, so with the same hand-welding, flux-cored wire of the variety, there is the location for the entire shipbuilding industry type flux cored wire, a low-temperature flux-cored wire for marine structures, there is used for boilers, heat-resistant pressure vessel steel flux cored wire, and so on.
(4) according to the different composition of the powder filling, can be divided into the slag-type flux-cored type flux cored wire metal powder flux cored wire. Slag-type flux cored wire according to the alkalinity can be divided into titanium slag type (acidic residue) , titanium calcium type (neutral or alkaline residue) and basic (alkaline residue) flux cored wire. In general, titanium cored wire weld is good, all-position welding operability is good, but the notch toughness , somewhat less crack resistance on the contrary Welding Wire China notch toughness. good crack resistance, and weld appearance. forming and operational backward. titania type flux cored wire in between in recent years With the development of flux-cored wire, the new titanium-based flux-cored welding process is not only good, and its proliferation of deposited metal with low hydrogen content, excellent toughness, while the lime-titania type flux cored wire is now rarely used. metal powder flux cored wire with a solid wire-type low-slag (slag produced small amounts), good crack resistance characteristics, and the mix of titanium cored wire welding operations good performance of its welding efficiency than the titanium-based medicine wires for even higher.
    Currently no agreed classification of flux-cored wire standard, many countries according to the type and flux-cored form of droplet transition flux-cored roughly classified into four types, namely, titanium, alkali type of metal powder-based and self-protection type flux cored wire.
