Heat exchanger tube/plate welding procedure qualification

Thread Content

When conducting welding procedure qualification for the tubes/plates of heat exchangers, can a combined test piece be used directly, without the need to create both a corner joint test piece and a butt joint test piece? NB/T47014-2011 Appendix D

This meets high standards; Appendix D of NB/T47014-2011 is also referenced.
