The material is P1 To P4 and It can be welded either by suitable consumable of P1 or P4 Generally it is preferred to weld by higher grade.
ii) When joint is to be heat treated, for P4 the min PWHT temp is 650 C
iii) For higher temp. multiple weld of 309L does not give good results and fails in bend
Therefore it is necessary to qualify PQR accordingly to set min PWHt temp.with respect to test results
