Hi team  

   What is welding electrodes need to used for rail welding CR210 material to S355jr

For welding CR210 rail steel to S355JR, you can use E 8018-C3, a low hydrogen electrode.

Pre-heat the joint (CR210) to 250-350  °C and maintain  a max. interpass temp of 300 °C. 

Optionally, use E312-16 (high alloy Cr–Ni electrode) for buttering the rail steel and complete 

with E 309L for a ductile joint.
