What welding electrode should be used for welding between Q235B and S30408?

Thread Content

I checked 47015, and there is no category for Q235B listed there. How should I choose the welding rod? When encountering intermaterial welding not specified in the standards, how should electrodes, wires, and fluxes be selected?

This belongs to the same category as Q245R; select the welding material accordingly.

Generally, higher-grade materials are used for welding, while lower-grade materials are used for heat treatment

Material groups and categories are specified in NB/T 47014 \"Welding Procedure Qualification for Pressure Equipment\".

A302 is the welding rod equivalent to E309-16
