D707electrode
electrode D707
Introduction: D707 is a kind of tungsten carbide surfacing electrode with low-hydrogen natrium type coating and carbon steel core wire. Its transition depends on the carbide alloy in the coating. The tungsten content in the surfacing metal is 40-50%. Due to the thicker coating, the sleeve is longer in welding. After the coating turns red, it can easily fall off in little pieces, so DCRP (Direct Current Reversed Polarity) and weaker current is suitable. | ||||||||||
Uses: Used for surfacing welding on intense rock wear-resistant machinery elements, such as blades of concrete mixers, blades of bulldozers and pumps, blades of dredgers, high speed sand mixing boxes, etc. | ||||||||||

Instructions:1.The electrodes must be baked under 300-350°C for an hour before welding.2. If the weldments are steel, the preheating temperature should be over 300°C. If the weldments are low-alloy steel, it should be 400-500°C. If the weldments are stainless steel, it should be 600-650°C.3. Low-alloy steel and stainless steel must be annealed under 700°C. |
