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: 205~260°C,PWHT:725~755°C
