Hi,
Is there any problem to weld API 5000 4130 low alloy steel with A333 Gr. 6 pipe? Does anyone see any welding issue here? I appreciate your advice.
Thanks.

1) Preheat and interpass 200°C min.
2) Soak for 2 hr min. @ 200-250°C.
3) Straight to PWHT @1250 for 1 hour. Cooling to room temp. is acceptable.
