Golden Bridge E71T-1C-J (JQ-YJ501-1L) Flux-Cored Welding Wire
SKU:JQ-YJ501-1L-045-0011
JQ-YJ501-1L
JQ-YJ501-1L is a titanium dioxide CO2 gas shielded flux-cored welding wire, which has excellent welding performance with soft and smooth arc, low spatter level, effortless slag removal ability and optimal bead appearance. It is permitted for all-position welding. The welding efficiency is high. The deposited metal is toughened by trace elements, which has excellent low-temperature toughness at -40℃ and good crack resistance.
The product is applicable for welding structural steel with tensile strength of 490MPa, commonly applied in the fields such as ships, bridges, construction machinery, marine engineering, coal mining machinery, construction machinery and so on.
