WPS and PQR in Resistance Welding – Purpose, Content and Standards · 模型 49170
In resistance welding processes (such as resistance spot welding), the Welding Procedure Specification (WPS) and the Procedure Qualification Record (PQR) are essential documents used to ensure weld quality, process consistency, and standard compliance. The WPS defines how the welding operation shall be performed and typically includes: Welding process designation (ISO 4063 – Resistance Welding) Base material grade, thickness range, and material combination Electrode material, tip geometry, and cooling method Welding current, welding time, electrode force, and holding time Weld layout, spot spacing, and acceptance criteria (nugget size) The PQR validates the WPS by recording the actual welding parameters applied during test welds and the results of qualification tests, such as peel tests, chisel tests, macro examinations, and visual inspection. This qualification confirms that the selected WPS parameters produce sound and repeatable welds. The use of WPS and PQR in resistance welding supports controlled production, reduced defects, and traceability, and is aligned with international standards including: ISO 14327 – Resistance spot and projection welding ISO 15614-12 – Welding procedure qualification for resistance welding ISO 17657 – Resistance welding parameters and testing ISO 9606-4 – Resistance welding operator qualification AWS D8.1 / AWS C1.1 – Resistance welding requirements
