WPS FOR AISI 4130 with API 5L X60

[Siva Chidambaram]

 Hi,

 

I need some guidance for preparing WPS for AISI 4130 with API5L X60. Following are the stages of the WPS Preparation.

 

1. Carrying out 10 mm buttering on AISI 4130 end with suitable carbon steel consumable,
2. Carrying out stress relieving at 704 – 749 C as per the applicable thickness,
3. Carrying  out beveling on buttered face; ensure that there is minimum of 6mm buttering after machining.
4. Carrying out welding of buttered AISI 4130 to API 5L X60 material with carbon steel consumable.
5. Carrying out stress relieving at 610 – 630 C of the joint, only in case, if the thickness of API 5L X60 is more than 20 mm. For thickness lesser than 20 mm, stress relieving is not required.

 

Kindly suggested me the suitable Buttering electrode for the above mentioned, also the Electrode for the combination.

 

Thanks and regards,
