Many designs will consider both yield strength and tensile strength.
Yield strength and tensile strength of base material need to be separately measured and satisfied for the design.
As an example, the test result is a yield strength of 270 MPa for the base material and a tensile strength of...
So, the acceptance level of NDT of mechanical property tests should not be stricter than that of non-destructive testing for production welds. Am I right? Thank you.
The understanding of this sentence is that the mechanical properties test plate shall be non-destructively tested and the test specimen will be taken from sound areas and will not be taken from the defective location of the test plate.
Thanks.
Thank you.The key is that the steel has undergone 100% non-destructive testing and meets EN 10160:1999 S1/E1 grade or ASTM A 578:2017 grade C.
However, for the steel that has already been UT qualified, defects were found in the base metal during non-destructive testing of the weld area after...
Thank you, noting that this requirement is not a requirement for Welding Process Qualification Test Plate or for NDT of the pressure vessel product.
This requirement is appied to production test plates.
In order to control the continuing quality of the manufacture and the compliance of the...
Thank you
For heavy thick plates, ultrasonic testing is performed in accordance with either EN 10160:1999 Level S1/E1 or ASTM A 578:2017 Level C.
For weld of the heavy thick plates, TOFD is required and the acceptance criteria is ISO 15626 level 1, or PAUT is required and the acceptance criteria...
May I ask if colleagues have any experience in non-destructive testing of thick plates?
Where thick plates (steel plates with a thickness greater than 100mm) ，the steel mill has conducted 100% ultrasonic testing and passed it.
Then, during non-destructive testing of the weld after welding at...

Thank you all for your expert comments. Based on the comments, does it show that ISO 15614-5 is too strict and impractical for bending tests?The requirements in AWS D1.9 for welding procedure test are more in line with practice? Thank you.
Thank you for your professional comment.
We agree that bending of titanium alloy weldments is not an easy task. AWS D1.9-2015 Structural Welding Code-Titanium has also been reviewed. It has been noted that its requirements for bending tests are different from ISO standards.

The diameter of the former or the inner roller shall be 6 t except for material group 51 when 4 t shall be used. The bending angle shall be 180° for parent metal with elongation A ≥ 20%. For parent...
Dear sir,
Tensile test results of the half that are testing are generally identical to the test result of the other half.
However tensile test results of the half thickness tensile specimen will be identical to the test result of the full thickness tensile specimen. Or what is the relationship...
