Modification History

Release 1. Supersedes and is equivalent to LMTTF3004A Perform advanced welding of plastic materials

Application

This unit of competency 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.

The unit of competency applies to the welding of plastic in the textile fabrication industry. Work may be conducted in a variety of environments, such as operational indoor or outdoor workplaces, and 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.

No licensing, legislative or certification requirements apply to this unit at the time of publication.
