Re: [MW:26391] Re: Welding of ASTM A 335Gr.P11

Dear sir,

  Thanks for your valuable  reply, i also suggested the ER-80SB2 & E-8018B2 for welding of P11, but the chinese has saying that,they will use ER-90SB3 & E-9018B3 instead of ER-80SB2 & E-8018B2 . Till now QPS & PQR also not prepared.for that reason only i asked here. i have to approve the proposed WPS. please let me know the soaking temperature have to given when ER-90SB3 & E-9018B3 used for P11.Is there any effect on the hardness values when we will give soaking temperature of P11.

Thanks & Regrds

Dear Friend,

For  welding of SA335-P11 pipe you can use ER-80S-B2 & E8018-B2 for welding, no need to use 

ER-90SB3 & E-9018B3. 

For PWHT you can use 650-660 Deg C with soaking time respect to thickness of job or refer ASME secVIII div 1 standard.

Hope that i have clarified.

Dear sir,

  i'm having one doubt that, can i use ER-90SB3 & E-9018B3 for welding of SA335-P11. if suppose will use then what is temperature should have to follow for the PWHT. if we follow the soaking temperature of P11, then is ther any chance to affect on the hardness properties.

Thanks & regards
