Overview
CEN/TR 16862:2023 provides guidance for the role of the Plastics Welding Supervisor (PWS), defining the tasks, responsibilities, required knowledge, skills and competence necessary to supervise welding of products and semi-finished products made of thermoplastic materials. Applicable to all thermoplastic welding processes, this Technical Report helps organizations demonstrate sound management of welding activities and ensure consistent weld quality and compliance with project requirements.
Key topics and requirements
- Scope and role: Defines the PWS as a person employed by the welding organization and competent to perform welding supervision activities.
- Tasks and responsibilities: Detailed pre-welding, during-welding and post-welding duties, including:
- Contract and technical document review (welding procedures, test plans, welding plans)
- Verification of materials, labelling, storage and dimensional conformity
- Assessment of the welding environment and readiness of welding and testing equipment
- Verification of welder qualifications and distribution of work instructions
- Monitoring of weldability and execution of intermediate visual inspections
- Oversight of destructive and non‑destructive testing and acceptance criteria
- Recording evidence, managing non-conformities and participating in corrective actions
- Competence framework: Specifies required knowledge, skills and practical experience. Competence can be achieved via informal or non-formal learning and must cover technical, health, safety and environmental aspects.
- Documentation and traceability: PWS must record objective evidence of inspections, test results and releases of welded joints.
Practical applications - who uses this standard
