Elements and Performance Criteria

1. Prepare to weld
   • Job requirements are determined from workplace instructions
   • Welding information is accessed and interpreted
   • Materials for thermoplastic welding are selected and inspected for quality
   • Hazards associated with the work are identified and risks are managed
   • Thermoplastic welding tools and equipment and PPE are selected and checked for serviceability
   • Work is planned to minimise waste and use time efficiently
2. Carry out thermoplastic welding activities
   • Work area and fume extraction system are prepared ready for thermoplastic welding
   • Thermoplastic welding equipment is set up and adjusted for specific job requirement following vehicle manufacturer specification
   • Reinforcement methods are applied to ensure pre-damage strength
   • Thermoplastic welding equipment is used according to workplace procedures and safety and environmental requirements
   • Thermoplastic weld is finished to pre-paint condition and completed without causing damage to vehicle or components
   • Completed thermoplastic weld is inspected for quality and faults are identified and rectified as required and according to workplace procedures
3. Complete work processes
   • Final inspection is made to ensure work meets workplace expectations and component is presented ready for use
   • Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected and stored
   • Tools and equipment are checked, reported if faulty, and stored according to workplace procedures
