Elements and Performance Criteria

1. Identify the materials and process for joining
   • The process and materials to be used are identified
   • The effect of the joining process on the materials is determined
   • The effect of the chemical reactions on the materials is determined
   • Allowances for joining overlaps are checked in workplace documentation and manufacturer instructions
   • Curing times are identified for the materials and the process
2. Plan the joining process
   • Manufacturer instructions and workplace procedures for the joining task are used in the planning process
   • Work health and safety (WHS) requirements, including ergonomic criteria and personal protection needs, are observed throughout the work
   • Work sequence is planned noting appropriate curing/cooling times, efficient work sequence and quality requirements
3. Set up equipment and materials for the process
   • Tools, equipment and materials are selected and checked prior to use to ensure that they are appropriate for the work, serviceable and in a safe condition
   • Site is checked for appropriate ventilation, fume extraction and protection of other surfaces from contamination with screens and or covers
   • Adjustments and settings are made to suit materials, manufacturer instructions and workplace procedures
   • Appropriate personal protection equipment is selected and used
4. Follow workplace procedures to complete the joining process
   • Joining procedures are completed following the planned work sequence
   • Checks and tests of the process and the finished product are made
   • Appropriate adjustments are made to the process to maintain the quality of the finished product
   • Workplace documentation and records are completed as required

Performance Evidence

Interpret work order and locate and apply relevant information

Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment

Identify materials used in the work process

Follow work instructions, operating procedures and inspection processes to:

minimise the risk of injury to self or others

prevent damage to goods, equipment and products

maintain required production output and product quality

Locate, interpret and apply information relevant to the chemicals and textiles involved and apply safe handling practices for equipment, products and materials

Select appropriate materials and joining process to match work requirements and conduct the joining process within workplace quality parameters to chemically join at least three (3) textiles, including plain and patterned fabric, vinyl and velvet

Use mathematical ideas and techniques to correctly complete measurements, calculate area and estimate material requirements

Communicate ideas and information to enable confirmation of work requirements and specifications and the reporting of work outcomes and problems, interpret basic plans and follow safety procedures

Avoid backtracking, work flow interruptions or wastage

Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity
