Elements and Performance Criteria

1. Prepare for spot welding
   • Job requirements are determined from workplace instructions
   • Welding information is accessed and interpreted
   • Materials for repairs and replacements are selected and inspected for quality
   • Hazards associated with the work are identified and risks are managed
   • Tools and equipment, including personal protective equipment (PPE), are selected and checked for serviceability
   • Work area is prepared and work is planned to conduct and test spot welds, minimise waste, and use time efficiently
2. Carry out spot welding activities
   • Surfaces are prepared for spot welding and anti-corrosion coatings are applied prior to spot welding
   • Welding equipment is set up and adjusted for specific welding job requirement following OEM or authorised agency repair guidelines
   • Sample spot welds are performed and destructive tested
   • Welding is carried out using welding equipment according to workplace procedures and safety and environmental requirements
   • Spot welding is completed without causing damage to components or systems
   • Completed spot welds are inspected for quality, and identified faults are rectified as required 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
   • Workplace documentation is processed according to workplace procedures
