ISO 15614-1:2017标准中有以下说明Specification and qualification of welding procedures that were made in accordance with previous editions of this document may be used for any application for which the current edition is specified. In this case, the ranges of qualification of previous editions remain applicable.It is also possible to create a new WPQR (welding procedure qualification record) range of qualification according to this edition based on the existing qualified WPQR, provided the technical intent of the testing requirements of this document has been satisfied.从第二句话，是否可以说，如果按照2017年版本做的PQR，现在是否可以按照2017版本的覆盖范围来执行呢，比如2012版本，12mm角焊缝的覆盖范围是6-24，现在按照2017版，覆盖范围可以为3-24.
