This structure allows a welding engineer to follow a logical flow: write a preliminary procedure → weld a test piece according to the standard → examine and test the test piece → evaluate against acceptance criteria → and finally, define the limits within which the qualified procedure can be used in production. : The thickness of both the base metal

To ensure these protective layers perform reliably under harsh operational conditions, manufacturers must qualify their welding processes. This is where becomes essential. What is EN ISO 15614-7? iTeh Standards Accessing the PDF This structure allows

The standard provides the rules for preparing and testing a Welding Procedure Qualification Record (WPQR) specifically for these surfacing applications. Key Structure of the Standard

A test piece must be produced, mimicking the production weld.

What is the primary goal of the overlay ( or wear/hardfacing )?
