Description
This unit describes the skills and knowledge required to weld plastic components using extrusion welding techniques, both in the field and under factory conditions. This unit applies to an experienced technician working alone or as part of a team.The unit principally refers to the planning for, setting up, performing and quality-checking the weld, and maintaining and calibrating the equipment used.No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
