Classification


Application and Features 

• It is suitable for welding 540N/mm grade steel for low temperature resistance
• Good weldability and X-ray quality welds
• Weld metal contains 2.5%Ni and good impact properties at -60°C
• Ideal for welding low temperature machine, Al-killed steel for low temperature and 2.5%Ni steel, such as JIS G3127 and SL2N 255

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. High heat input will lower the impact value. Please carefully select the welding current
5. The preheat temperature for thick plate is 50~100°C

Application
- Ideal for welding low temperature machine
