Re: [MW:26416] Re: Welding of ASTM A 335Gr.P11

Dear Friend,

when using ER-90SB3 & E-9018B3 consumable for P11 pipe welding,you can use 690-700 Deg C with soaking time respect to thickness of job, when high alloy consumable is using on low alloy  we have to follow high alloy (P5A) condtion in ASME sec VIII div 1 standard.

Hope that i have clarified.

Dear sir, 

   Thanks for your valuable reply, actually we are not going to use ER-90SB9 & E-9018B9, CHINESE  proposed to do weld with ER-90SB3 & E-9018B3. for this please suggest me what temperature have to give for soaking and holding time. for your valuble reply i'm awaiting sir.

Thanks & Regards

There will be depletion of C and Hardness also will increase if u use ER90S-B9 and E9018-B9 and soaking time of P11 will not reduce much of Hardness of B9 weld metal

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
