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 %
What is the book to look ? 31.3 book or asme sec 8 ?
When we can say this is rounded or linear indication ?
Sir DPT me kitni depth tk ka defect find out kr skte hai

As per ASME 31.3 what are the RT requirements of socket weld in severe cycle service

Undercut depth is allowable upto 1 mm and the tw/4 is the length of undercut..
Good ✨👍✨
Thank you! Cheers!
What about non linear indication for ultrasonic acceptance
Depth of under cut
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
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 ..

What is Tw sir?
Thickness of weld ..
can you give me this presentation
