Dear Sirs,
-- Please confirm the following weld details for my below 2 queries.
We have a tube to tube welding , in which the material is SB407 UNS N08810 ( P No. 45 ) and the design temperature is about 800 Deg C.
1) Can we use either ERNiCr3 GTAW weld rod Or ERNiCrMo-3 considering the above design temperature for UNS N08810, without having metallurgy issues , cracking etc?
Or which is the best suitable AWS class GTAW rod to withstand 800 Deg C for this weld?
2) To weld dissimilar materials , that is SB407 UNS N08810 ( P No. 45 ) to A312 TP 321H ( P No. 8 ), can we use ERNiCrMo-3 for a design temperature about 800 Deg C ?
Please give me some advice.
Best regards,
Saravanan Sornam,
