Two what is the material of welding wire?
Two wire is also called carbon dioxide gas shielded welding wire. It is a kind of welding wire specially used for CO2 gas shielded welding. It is usually rolled into rolls to facilitate mechanization and automation.Due to the porosity and splash phenomenon of two welding, resulting in the lack of defects such as welding joint strength, in order to prevent these problems, ensure that the mechanical properties of the weld, welding wire containing alloy -- requirements of silicon and manganese enough elements combined deoxidation, low carbon content below 0.1%.Two commonly used welding wire diameter series: Phi 0.8mm, Phi 0.9mm, Phi 1.0mm, Phi 1.2mm, Phi 1.6mm, wire diameter allowable deviation range +0.01, -0.04.Welding wires for low carbon steel and low alloy steel: H08MnSiA, H08MnSi, H10MnSi.Welding wires for low alloy steel, high strength steel: H08Mn2SiA, H10MnSiMo, H10Mn2SiMoA.Welding line for welded bainitic steel: H08Cr3Mn2MoA.Welding anti micro hole welding seam with low spatter: H0Cr18Ni9, H1Cr18Ni9, H1Cr18Ni9Ti.Welding wire for stainless steel sheet: H0Cr18Ni9, H1Cr18Ni9, H1Cr18Ni9Ti, H1Cr18Ni9Nb.
The steel base has many alloy elements, but the carbon content is very low, and the surface is coated with a thin layer of copper, so it looks golden.
