▎Applications and Features

It is suitable for welding 540N/mm2 grade steel for low temperature resistance.
It provides superior weldability, stable arc and good slag removal
Weld metal contains 3%Ni-0.25%Mo and good impact properties at -60°C.
It is ideal for welding in LNG storage tanks or 3.5%Ni steel for low temperature resistance.

▎Welding Position

▎Welding Instruction

Clean up the contaminations on the steel.
Dry the electrodes at 350~400°C for 60 minutes before welding.
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)
High heat input will lower the impact value. Please carefully select the welding current.
The preheat temperature for thick plate is 50~100°C

▎Application

It is ideal for welding in LNG storage tanks or 3.5%Ni steel for low temperature resistance.
