Welding Instruction
- The dilution rate deteriorates the hardness and corrosion resistance
- Dragging a 90-degree angle or a short arc can reduce the dilution of weld metal
- Preheat and Int. temperature should be 400~500°C. Use slow cooling after welding to prevent cracks
- Dry the electrodes at 200-250°C for 30-60 minutes before use
Application
- It is suitable for injection molding screws, high temperature turbine blades, deep drawing mold and bearing
