Product name:KN-816C2
 
Classification:E8016-C2
 
 

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

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.
