Dear all,
I have a doubt in welding of Gr.11 material with Gr. 91 material.
The details are as follow:
Joint Type: Fillet weld
Material; SA 213 Gr. T91 with SA 213 Gr. T11
Process: GTAW & Also in SMAW
Consumable: For GTAW: ER 80S-B2 & for SMAW : E8018-B2
Preheating: 200°C
PWHT: 745° ± 15°C
In this welding, Whether there will be any metallurgical problem. If so what is the alternate for it.
