Submerged arc open-arc surfacing flux-cored wire




Note: The submerged arc surfacing flux-cored wire, the welding wire is straight when welding, with HJ107, the welding process has excellent performance, beautiful forming, and easy slag removal. The metal of the surfacing layer is a low-carbon alloy of chromium and tungsten, which has a precipitation strengthening effect. Disperse carbides are precipitated at high temperatures, which can maintain good high-temperature strength and hardness, so it has excellent tempering resistance and wear resistance. Uses: Used for surfacing intermediate rolls, work rolls and hot-rolled squeeze rolls. Specification (mm) Current (A) Voltage (V) Welding speed Φ3.2350 ~ 45029 ~ 32350 ~ 500mm / Min Surfacing process: 1. Clean the oil and rust before surfacing and remove the fatigue layer. 2. The workpiece should be preheated to 420 ° C before welding and kept warm. 3. Immediately after welding. 4. Stress relief and tempering should be performed immediately after welding. Surfacing layer hardness: HRC≥60 ~ 65
