- 23 projection welding (231 indirect, 232 direct)
- Test programme elements - Requirements for preliminary WPS (pWPS), welding procedure test pieces, specimen shapes/dimensions, macrosections and destructive testing.
- Examination and testing - Visual inspection, destructive tests (e.g., torsion tests referenced in ISO 17653), cutting locations for specimens, and re‑testing rules.
- Range of qualification - Defines what aspects a single qualification may cover, including:
- manufacturer and equipment limits
- material families and thickness ranges
- welding process, type of current, welding cycle
- pre/post‑weld heat treatment and electrode specifications
- Documentation - Preparation of a Welding Procedure Qualification Record (WPQR) capturing tested parameters and limits of validity.
Practical applications and users
- Intended users:
- Welding engineers, QA/QC managers, and procedure writers
- Fabricators and manufacturers in automotive, electronics, appliance and general sheet‑metal industries
- Inspection bodies and testing laboratories that perform WPS/WPQR qualification
- Typical applications:
- Qualifying spot welds for car body assemblies and battery pack joints
- Validating seam welds for fuel tanks, containers and HVAC ducts
- Establishing projection weld procedures for nut/stud attachment on assemblies
- Benefits:
- Ensures consistent, reproducible resistance welding quality
- Provides documented limits for production transfer and auditability
