Socket weld and branch connections weld which are not radiographer shall be examined by magnetic particle or lpt methods in accordance with Para 344.3 or 344.4
sir my question is how much allowance of depht of undercut we can accept you said not exced 1mm for less or equal one by four of thickness of the weld, i didnrt understand weld that part can you clarify me please?
generally it is less that 3 percent , however it is not mentioned in any codes and standard .Please follow client requirement and how to calculate the percentage please see below . if welder did 100 joints but RT requirement is only 10%. so we took 10 joint RT. and suppose we have 2 joint repair in those RT joints than %repair = 2/10 * 100 = 20 %

When we can say this is rounded or linear indication ?
Very useful vedio
Thanks, please subscribe to get more video
Good ✨👍✨
Thank you! Cheers!
Interesting video

Sir can you make video on aws D1.1 radiographic testing
Hi Sir,
I have a doubt on B31.3 PWHT requirements. Could you please explain what is the minimum thickness required for PWHT for P No.1 ?
Thank you
19mm
What about non linear indication for ultrasonic acceptance
As per ASME 31.3 what are the RT requirements of socket weld in severe cycle service

Depth of under cut

Undercut depth is allowable upto 1 mm and the tw/4 is the length of undercut..
Sir code book is given in the examination or not ?
What's the difference between UT & DAC?
kindly share the allowable welder repair rate percentage for process piping and pipeline.
will upload a video on this ..Thanks ..

Sir DPT me kitni depth tk ka defect find out kr skte hai
Dpt me only surface defect detect hota hai.. And in mpi surface and subsurface defect detect hota hai upto 5 mm depth
@@WeldingNDTInspection thank u sir👍
Sir what is meaning liner indication ( symbol F) individual lenght =
You are right.
T/10 for T less than 3 mm
0.5 mm for T from 3 mm to 6 mm
1 mm for T greater than 6 mm to 50 mm
1.5 mm for T greater than 50 mm
Clear not picture
What is Tw sir?
Thickness of weld ..
can you give me this presentation
