[MW:12324] Code Explanations

Hello Gents,

 I want to  carry out  a welding  procedure qualification testing for  welding jackets structural members, the applicable construction code is AWS D1.1. Project  material is API 2W Gr 50 pipe rolled from TMCP plates, and job  maximum thickness is 76.2mm,and project  requires  CVN testing at (-40°C).

1.      What will  be  the best combination of thickness ( T1 & T2 )for the pipes  to produce a TKY joint that will pass CVN testing at the above job required CVN testing temperature ?  will PWHT be applicable as per code? Also specify code references.

2.      Will these qualification qualifies welding on API 2MT1 Gr 50  pipes rolled from TMCP plates  with thickness 50.8mm with CVN requirement of (-30°C).

3.       I am required to make  a procedure for welding pressure vessel of thickness 75mm as per ASME VIII DIV 1,  project material is ASTM A 516 Gr 70 N  and project requires cvn testing at (-30°C), will it be possible  to qualify these procedure with a lesser thickness of the same material, will it  meet  the impact requirement  as per applicable  code? Please help with your contributions and provide applicable code references
