EN ISO 15614-7 is a standard that specifies the requirements for the qualification of welding personnel who perform resistance welding operations. Resistance welding is a process that uses electrical resistance to generate heat and join two metal parts together. This standard provides a framework for assessing the competence of welding personnel to ensure that they have the necessary skills, knowledge, and experience to perform resistance welding operations safely and effectively.
The benefits of EN ISO 15614-7 include:
Mandatory for checking the bond integrity between the overlay and the base metal, as well as detecting internal voids or slag inclusions. Destructive Testing
Before cutting the test coupon for mechanical tests, it must pass 100% surface and volumetric inspections: en iso 15614-7 pdf
Overlay welding, also known as cladding or hardfacing, is not used to join two pieces together. Instead, it deposits a layer of weld metal onto a surface to achieve desired dimensions or specific properties, such as:
: To check for volumetric defects like lack of fusion. 3. Destructive Testing Requirements
Identify the required surface chemistry, wear profile, and base metal.
It defines how a preliminary welding procedure specification (pWPS) is qualified through specific tests to ensure the overlay meets chemical and mechanical property requirements. Because EN ISO 15614-7 is a copyrighted document
All sample coupon construction must be actively witnessed by an approved independent third-party examiner or an accredited examining body. The witness verifies that all variables strictly match the initial variables defined on the pWPS. Non-Destructive and Destructive Testing Requirements
The acceptance criteria for each of these tests are defined in Clause 7.5.
: Multi-process combinations require strict adherence to individual process limits.
EN ISO 15614-7 is an important standard that ensures welding personnel are properly qualified and trained. The standard provides guidelines for the qualification of welding personnel for fusion welding of metallic materials. By following this guide, you can understand the requirements and benefits of EN ISO 15614-7 and obtain a copy of the standard. This standard provides a framework for assessing the
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.
A cross-section is polished and etched to examine the weld run sequence, penetration profile, and heat-affected zone (HAZ).
The standard applies to all welding processes suitable for overlay welding, such as manual metal arc, gas-shielded, and plasma welding. It is primarily used for:
