Description
This unit covers the skills and knowledge required to perform high frequency welding of plastic materials using equipment within the safe operating parameters of the equipment used.
Notes
Elements and Performance Criteria
1 Prepare for welding
  • 1.1 Material to be welded is examined and prepared for welding
  • 1.2 Work is planned to maximise safety and productivity
  • 1.3 Suitable electrical power outlets, if required, are identified
  • 1.4 Safe working environment is established and welding equipment checked for serviceability
  • 1.5 Workplace procedures and instructions are read and interpreted
2 Select and prepare tools
  • 2.1 Appropriate supplementary hand and power tools are selected and prepared for the job
  • 2.2 Extension power cables are checked for knots and insulation damage
  • 2.3 Electrical tools are checked for safe connection to power supply
  • 2.4 Tools are examined for damage, missing components or other defects (including frayed power cords where applicable)
  • 2.5 Safety equipment is used during tool operation in accordance with OHS practices
  • 2.6 Required tasks are performed using tools in accordance with OHS practices
  • 2.7 Tools are located in a safe position when not in use
  • 2.8 Tools and extension cords are cleaned and stored in accordance with industry and OHS practices
3 Perform high frequency welding
  • 3.1 Surfaces of material are prepared for welding
  • 3.2 Material is laid out on working table or other suitable surface and anchored to prevent movement
  • 3.3 Equipment temperature or operating frequency is adjusted to prescribed settings
  • 3.4 Screens or barriers, where fitted, are lowered prior to welding process
  • 3.5 Operator and bystanders are kept at an appropriate distance or suitably protected when high frequency welding is being undertaken
  • 3.6 Welding equipment is operated in accordance with OHS practices
  • 3.7 Weld area is examined or tested for correct fusion of materials
  • 3.8 Problems or faults are identified and addressed
  • 3.9 Work piece is removed
4 Inspect quality, labelling and documentation
  • 4.1 Completed weld is informally inspected to verify that it appears to be of an acceptable standard
  • 4.2 Completed product is labelled or tagged and any necessary documentation completed in accordance with workplace procedures
5 Clean up and maintain equipment
  • 5.1 Work area is cleaned and tools and electrical equipment are stowed away
