Re: [MW:25484] Impact Test

if the engineering goes by the book you have to repeat the impact test. How was the ferrite?

Dear All,

 

Material:                        SS304l ( 5 mm Thick Pipe ASTM A312 TP304L)

Code:                           ASME B31.3

Design Temperature:     -198 Deg C

Welding process:          GTAW

 

 

The available WPS/PQR tested  @ -196 Deg C with GTAW Process in accordance with ASME SEC IX and ASME B31.3 but design temperature -198 Deg C as above indicated material, Can we use available procedure to weld above material.

 

Thanks & Regards,

Mohd. Azam
