Defines the types of overlay welding covered (including manual, mechanized, and automatic processes).
Meeting client requirements for certified overlay welding.
Is this overlay for or wear resistance (hardfacing) ? en iso 15614-7 pdf
Yes. The standard explicitly addresses this scenario: "In situations where qualification is carried out on a pre‑production test piece, the qualification is performed in accordance with ISO 15613 except that, as far as possible, the testing is according to this part of ISO 15614." This means you can integrate the qualification test into an actual production component, provided the testing follows the requirements of Part 7.

It does not apply to hardfacing applications where cracking is intentional. Scope and Structure of ISO 15614-7:2016
Liquid Penetrant or Magnetic Particle testing looks for micro-fissures in overlapping zones. Volumetric Testing (UT/RT)
The scope of the standard is precisely defined. It . It defines the conditions for executing those tests and the range of qualification for all practical welding operations that fall within the variables listed in Clause 8 of the document. When looking to source the , it is
is a critical international standard that specifies how to qualify a welding procedure for overlay welding through standardized tests
Many global contracts specifically mandate qualification to ISO standards.
: Standard joint welding, geometric build-ups, structural repair of parent metal, and base-material restoration are strictly excluded from Part 7. These applications must utilize ISO 15614-1 (for structural steels and nickel alloys) or ISO 15613 (for pre-production testing).
To successfully qualify a WPS under EN ISO 15614-7, your test piece must undergo rigorous inspection. The standard outlines a specific battery of tests: Non-Destructive Testing (NDT)
