JQ·YJ501-1 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 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.
1. The work piece shall be degreased and derusted before welding. 2. When welding, the gas flow rate is generally 20-25L/min. 3. When welding flux-cored welding wire, the dry extension length should be 15-25mm. 4. The humidity of welding wire warehouse should be kept below 60%. 5. The welding wire without vacuum package should not be stored for more than half a year and welding wire with vacuum package should not be stored for more than a year
