Hi, There are two scenarios which are described below . 1. Base metal Qualification  For Base metal Qualification as you attached snap & QW : 451 you get Range of base metal  thickness qualified. 2. Weld metal Qualification Please refer QW -451 where code mentioned max. Weld metal qualified on your each process.Please refer attached snap for your reference. I hope your doubts are clear now.

Dears, Is there any exemption for shell Nozzle and shell manways greater than 2" diameter (as a prefabricated assembly ) from PWHT.  MOC : Group V material as per API 650 (ASTM A 516 Gr 70 N) Any clause interpretation with API 650 13th edition is highly appreciated.

Hello. I am one of the welding quality managers who cooperate with representative semiconductor companies. Our customer has their own acceptance criterion that refer some international code such as ASME Section IX, BPE, 31.3, SEMI F81 etc. Recently, one of the related codes was questioned. It refers about the "Light Straw Color" in SEMI F81 regarding to the acceptance criteria of automatic welding surface color. We are using M200 automatic welding machine. There is no included any picture and details of it. Therefore, I wasn't able to find any exact standard of it. How could I verify that criteria. It's surface standard. It's not about the back bead which has certain criterion like AWS D18.2 or ASME BPE. I would like to get some advices related to this from your various experiences. Thank you. -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Grou...

Dear sahil , As per ASME UW -42 (Surface weld build up) ,  1. You should have qualified procedure for Butt Joint. 2. If you performed Buttering than you should go for NDT (Either MPT or LPE Test) on buttering area . For Hydro Test , As per UG - 99 ,Hydro Test shall be performed after completion of all the fabrication work & NDT work . You again need to perform Hydro Test to comply code requirement. For PWHT , Please provide Material Grade for further detail.   On Thu, Jan 20, 2022 at 10:09 AM Shahil Saini < sainishahil98@gmail.com > wrote: yes jenish, i am talking about buttering,  Below attached figure will clear my question to you.

Hi, As per Table UCS56-1- Note (b) of Section VIII,Div.1 , for 32mm to 38mm thickness PWHT is not mandatory as below. But hydrostatic test to be done as per the drawing & Design requirements. GENERAL NOTES: (a) When it is impractical to postweld heat treat at the temperature specified in this Table, it is permissible to carry out the postweld heat treatment at lower temperatures for longer periods of time in accordance with Table UCS-56.1. (b) Postweld heat treatment is mandatory under the following conditions: (1) for welded joints over 11/2 in. (38 mm) nominal thickness; (2) for welded joints over 11/4 in. (32 mm) nominal thickness through 11/2 in. (38 mm) nominal thickness unless preheat is applied at a minimum temperature of 200°F (95°C) during welding. This preheat need not be applied to SA-841 Grades A and B, provided that the carbon content and carbon equivalent (CE) for the plate material, by heat analysis, do not exceed 0.14% and 0.40%, respectively, where Thanks& Rega...
