Bulldozer blade

Welding Position


Welding Instruction

• Dry the electrodes at 300-350°C for 30-60 minutes before use
• Clean up the contaminations on the work piece. Keep the arc as short as possible
• Take the back-step method to prevent porosity at the arc starting
• Preheat and the Interpass temperature should be ≥ 200°C
• Use high tensile strength low hydrogen electrode for the buffer layer in multi-layer build-up

Application
- It is suitable for repairing spiral conveyor, bulldozer and cutter
