Welding Position


Welding Instruction

1. Clean up the contaminations on the steel
2.  Dry the electrodes at 350~400°C for 60 minutes before welding
3. Keep arc as short as possible. Take the back step method to prevent porosity at arc start and re-start. (Please refer to Appendix A)
4. Preheat and interpass temperature: 100~200°C, PWHT: 600~635°C

Application
- Ideal for welding steel pipes, heat exchanger pipes, cast steel, rolled and forged steel
