In welding, do you want to re engineer the welding process if the change of the flux grade, such as SJ101, becomes SJ301?
No need to do it againWhen the Fe-1 type steel is submerged in multi-layer welding, the welding type should be re evaluated for changing the type of welding flux. These two are neutral flux, do not need
To re evaluate, refer to table 6. in NB/T47014
Yes, flux is the primary factor and needs to be re evaluated after the change
