Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Elements Elements describe the essential outcomes. | Performance Criteria Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section. |
1. Prepare to weld | 1.1 Job requirements are determined from workplace instructions 1.2 Welding information is accessed and interpreted 1.3 Materials for thermoplastic welding are selected and inspected for quality 1.4 Hazards associated with the work are identified and risks are managed 1.5 Thermoplastic welding tools and equipment and PPE are selected and checked for serviceability 1.6 Work is planned to minimise waste and use time efficiently |
2. Carry out thermoplastic welding activities | 2.1 Work area and fume extraction system are prepared ready for thermoplastic welding 2.2 Thermoplastic welding equipment is set up and adjusted for specific job requirement following vehicle manufacturer specification 2.3 Reinforcement methods are applied to ensure pre-damage strength 2.4 Thermoplastic welding equipment is used according to workplace procedures and safety and environmental requirements 2.5 Thermoplastic weld is finished to pre-paint condition and completed without causing damage to vehicle or components 2.6 Completed thermoplastic weld is inspected for quality and faults are identified and rectified as required and according to workplace procedures |
3. Complete work processes | 3.1 Final inspection is made to ensure work meets workplace expectations and component is presented ready for use 3.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected and stored 3.3 Tools and equipment are checked, reported if faulty, and stored according to workplace procedures 3.4 Workplace documentation is processed according to workplace procedures |
This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.
Welding information must include: | vehicle manufacturer specifications workplace procedures thermoplastic safety data sheets (SDS). |
Safety and environmental requirements must include: | work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for: selecting and using PPE using SDS for thermoplastics manually handling vehicle components and welding equipment using tools and equipment using fume extraction equipment environmental requirements, including procedures for trapping, storing and disposing of waste materials. |
Before competency can be determined, individuals must demonstrate they can perform the following according to the standard defined in this unit’s elements, performance criteria, range of conditions and foundation skills:
carry out thermoplastic welding procedures on three different vehicle trim components, in which the work must involve:
two different types of thermoplastics
one weld to a minimum of 50 mm in length.
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS) and occupational health and safety (OHS) requirements relating to carrying out thermoplastic welding on vehicle trim components, including procedures for:
selecting and using personal protective equipment (PPE)
using safety data sheets (SDS) for thermoplastics
manually handling vehicle components and welding equipment
using tools and equipment
using fume extraction equipment
environmental requirements, including procedures for trapping, storing and disposing of waste materials
vehicle manufacturer thermoplastic specifications
type and use of fume extraction systems
types and characteristics of plastics used in thermoplastic welding
types and operation of thermoplastic welding equipment, including:
set-up
operation
methods and techniques for thermoplastic welding
procedures for protecting vehicle and components during weld
procedures for final inspection of thermoplastic weld.
Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the thermoplastic welding that they have carried out, e.g. work orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions
SDS for thermoplastics
PPE required for thermoplastic welding
fume extraction systems
consumables and materials to weld thermoplastic
three different vehicle trim components specified in the performance evidence requiring thermoplastic welding
thermoplastic welder
tools, equipment and materials appropriate for carrying out thermoplastic welding.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
