Definition of welding wire
Welding wire is a wire welding material used as filler metal or at the same time as conductive. In gas welding and gas tungsten arc welding, the welding wire is used as the filler metal; in submerged arc welding, electroslag welding and other gas metal arc welding, the welding wire is both the filler metal and the conductive electrode. The surface of the welding wire is not coated with anti-oxidative flux.
Classification of welding wire
(1) According to the welding method, it can be divided into submerged arc welding wire, CO2 welding wire, tungsten argon arc welding wire, melting electrode argon arc welding wire, self-shielded welding wire and electroslag welding wire, etc.
(2) According to the shape and structure of the welding wire, it can be divided into solid welding wire, flux-cored welding wire and active welding wire.
(3) According to the applicable metal materials, it can be divided into low carbon steel welding wire, low alloy steel welding wire, hard alloy surfacing welding wire, aluminum, copper and cast iron welding wire, etc.
