Re: [MW:13467] RE: 13441] NDE FOR BUTT WELD

You can perform  PT for surface and RT & UT for subsurface .......

 

RT by placing the cut film on to the available area ( chances of missing HAZ region on one side)

UT by using Longitudinal Shear wave probes and normal probes ( weld shall be flush ground to ensure full coverage ) for subsurface and below surface

PT for surface

Since it is a austenitic SS UT may not be possible. It is not possible to form a tapered transition 1:3 as required by almost all ASME code sections, which would make RT easier?

It is a butt weld.

 

It is welding of SS 321 forged component (Nozzle) of bevel end with 90 el. Actually forged nozzle is without tapering.

Proper radiography is executed for the BW valves joints as shown in Photo-0060.

 

UT is also a problem since probe movement is possible at only one side (Towards elbow) and there is no inside access.

 

It is 100% Radiography lines with high pressure – 1500#.

Can somebody write me about the possibility of either radiography OR Ultrasonic testing of attached butt weld?

 

We have tried to carry out radiography with and without non metallic support as in the attached snaps but image is not clear.
