Assessment tool
Version 1.0 Issue Date: May 2024
This unit describes the performance outcomes required to carry out oxyacetylene brazing. It involves preparing for the task, selecting, setting up and operating an oxyacetylene welding plant, setting gas pressures, identifying and adjusting required flame appropriate to brazing requirements, selecting and using suitable personal protective equipment (PPE), performing oxyacetylene brazing to given specifications, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

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 oxyacetylene brazing procedures on the following:
butt joint of 1.00 mm steel, 150 mm long
fillet joint of 1.00 mm steel, 150 mm long
lap joint of 1.6 mm steel, 150 mm long
pipe joint of 1.6 mm steel, 50 mm diameter.
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS), and occupational health and safety (OHS) requirements relating to carrying out oxyacetylene brazing of components, including procedures for:
selecting and using personal protective equipment (PPE)
using specialist tools and equipment, including approved oxyacetylene brazing glasses
manually handling components and oxyacetylene equipment
identifying and controlling hazards
environmental requirements, including procedures for trapping, storing and disposing of waste materials
types and application of brazing materials, including fluxes and rods
use and operation of oxyacetylene plant, including procedures for setting and adjusting pressure and gauges
oxyacetylene flame identification and applications, including:
natural
carburising
oxidising
basic maintenance procedures for oxyacetylene equipment
methods and techniques for oxyacetylene brazing
procedures for reporting faults and material defects
procedures for final inspection and testing of brazed components.
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 oxyacetylene brazing activities 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
PPE required to use oxyacetylene brazing equipment
components to be brazed as specified in the performance evidence
brazing equipment, consumables and materials
oxyacetylene plant
tools, equipment and materials appropriate for carrying out oxyacetylene brazing.
