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...
For the tensile test of steel, tensile specimen with the full product thickness should be performed.
Particularly on very thick products where the capacity of the available testing machine is insufficient to allow the use of test specimen of full thickness, this may be reduced by machining one...
Dear Steve Jones
Thanks very much for your early reply.
For instance.
Steel A (the steel standard specifies an impact test temperature of -10 ℃),
Welding consumables B1 (welding consumables standard specifies impact test temperature -10 ℃)
Welding consumables B2 (the standard for welding...

Referring to ISO 15614-1, 8.4.4 level 2, When impact testing is required by the application standard at temperatures less than -20 ℃, for solid wire and rods with the same designation and nominal chemical compositions, the additional test piece is not required, even if changing the manufacturer...
Thank you for your reply. Would it be more appropriate to choose a moderately skilled welder( (with or without a welding qualification certificate) to weld the WPS test assembly?
Best regards
Do test piece for Welding Process Qualification testing need to be carried out by qualified welders? Is it allowed that test piece weled by unqualified welders? Thank you.
It was noticed a post on the forum in 2006 about the 200 series austenitic steel, unfortunately I am unable to reply at this time. Eighteen years have passed, and it is unclear to what extent the 200 series austenitic stainless steel has been applied. Recently, there have been applications for...
