Understanding EN ISO 15614-7: The Standard for Overlay Welding Procedure Tests
Comprehensive Guide to EN ISO 15614-7: Specification and Qualification of Welding Procedures for Metallic Materials
Outlines the mandatory destructive and non-destructive testing (NDT).
The standard specifies essential variables such as parent material, thickness, welding consumables, and heat input that, if changed, would require a new qualification.
For example, applying stainless steel or nickel alloys onto carbon steel. Hardfacing: Applying wear-resistant materials.
Having the exact testing requirements and acceptance criteria for NDT and destructive tests.
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
Intermediate layers applied between the base material and the final overlay.
The standard specifies the dimensions and shapes of the test pieces required to represent the production weld [3]. It dictates exactly how many samples need to be cut and tested. 3. Examination and Testing
Side-bend tests are frequently mandated to ensure the overlay layer does not delaminate or crack when subjected to mechanical strain. Essential Variables and Range of Qualification
