For Q345R and 09mnniDR, how should impact testing be carried out? What welding materials are suitable – 507 or W707?

W707 should be chosen, but due to the effect of base metal dilution on the Q345R side, the low-temperature impact toughness of the weld will decrease.

Since Q345R is used, the impact temperature is maintained above -20 degrees Celsius. There is no need to use low-temperature welding materials. Options such as J507R\J507RH can be chosen.

I think J507RH should work fine
