Submerged Arc Welding Wires EL12
Brief Introduction:
H08A (AWS EL8) used for automatic submerged arc welding low carbon steel and some low-alloy steel stuctures (such as 16Mn),doing with high Mn type welding flux
H08MnA (AWS EM12) for welding carbon steel and low-alloy steel structures of relevent strength grade along with flux
H10Mn2 (AWS EH14) used for automatic submerged arc welding carbon steel and low-alloy steel such as 16Mn, 14MnNb welding structures
Basic Information:
1. Standard: GB/T H08A: AWS EL8/EL12; JIS W11; ISO: 171B-SU11
2. Material: 5.5mm steel produced by Qingdao Steel
3. Surface: copper coated
4. Diameter: 2.0, 3.2, 4.0, 5.0mm
5. Application: Used together with fused flux 431 or sintered fluxes 301 and 501. Used for both high speed welding and filling welding on 50kg class base metals.
6. Features: It is a kind of low-manganese and low-silicon type welding wire. It matches with high-manganese and high-silicon type welding flux. It is not sensitive to the rust on the base metal. It has excellent bead molding and slag detachability. It is the most frequently used submerged-arc welding wire. Monopole or dipole. AC/DC.
