Weld plastic materials

Assessment tool

Version 1.0
Issue Date: May 2024


This unit applies to hot air and hot wedge welding of plastic in the textile fabrication industry. Work may be conducted in a variety of environments, such as:

operational indoor workplaces

operational outdoor workplaces

hazardous or exposed conditions

Work may be conducted in small to large scale enterprises and may involve individual and team activities. Work is performed within defined procedures under direct supervision.

The application of this unit is according to OHS practices of the enterprise and workplace practices, which may include:

requirements prescribed by legislation, awards, agreements and conditions of employment

standard operating procedures

work instructions

oral, written and visual communication

quality practices, including responsibility for maintenance of own work quality and contribution to quality improvement of team or section output

housekeeping

tasks related to environmental protection, waste disposal, pollution control and recycling

This unit requires the application of skills associated with planning and organising for the safe and effective use of welding processes and technology. This unit also requires an ability to interpret and communicate job related information, check the quality of outcomes and identify and address problems relating to own work. Self management skills are applied to ensure workplace and quality standards are achieved.

This unit covers the skills and knowledge required to weld plastic materials within the safe operating parameters of the equipment used.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
