Hi all,
We want to weld a Drilling tubular material with Vanes (rectangular shaped blades). Tubular material T-95 grade (API 5CT) of size 13” OD to be welded(fillet weld) with AISI 1040 carbon steel material of size 100 mm length x 15 mm thickness (rectangular bars).
What should be pre-heat and PWHT temperature to keep hardness value (weld metal & HAZ) within the acceptable range of API 5CT (i.e. 26 HRC max). What are the other parameters to be considered while qualifying the WPS?
Thank you in advance for your response.
