Flux Cored Welding Wire
Description:
it belongs to alkaline slag system CO2 gas - protected flux cored wire. Good welding process performance, stable arc, easy slag removal, good weld formation, suitable for flat welding and fillet welding and slope climbing welding no more than 45 degrees; Weld metal has good plastic-toughness and crack resistance, and low diffusion hydrogen content.
Application:
suitable for welding of low carbon steel with high requirements of plastic toughness and crack resistance and 490MPa grade high strength steel structure, mainly used for welding of important steel structures such as ships, machinery manufacturing, containers, petrochemical industry etc
