Description
This unit of competency covers the skills and knowledge required to butt weld polyethylene (PE) plastic pipelines. It applies to welding undertaken in the field and in factory conditions. Pipelines may be for transmission of gas or liquids.This unit of competency applies to experienced operators who are required to calculate appropriate welding parameters to be used, set up equipment, perform butt weld, assess joints against specifications and solve problems within area of responsibility.This unit of competency applies to an experienced operator demonstrating theoretical and technical knowledge and well developed skills in situations that require some discretion and judgement. The operator may work alone or as a member of a team or group and will work in liaison with other shift team members, team leader and supervisor, as appropriate.No licensing, legislative or certification requirements apply to this unit at the time of publication.
