Unit of competency
Modification History
Release 1. This is the first release of this unit of competency in the TLI Transport and Logistics Training Package.
Application
This unit involves the skills and knowledge required to weld rails, crossings and switches using an electric welding process in accordance with rail industry standards, safeworking and regulatory requirements, and workplace procedures. It includes using non-destructive testing to locate defects; preparing rails, crossings or switches for welding; gouging or grinding; setting up welding equipment; performing welding operations; checking weld conformance; and completing required documentation. These processes are used to repair rail surface defects and restore rail profile to plain rail, crossings and switches. People achieving competence in this unit will need to fulfil applicable state/territory legislated rail safety requirements and to comply with rail industry standards, codes of practice and/or guidelines. Work is performed under some supervision, generally in a team environment. It involves the application of routine operational principles and procedures when welding rail using an electric welding process, as part of workplace activities across a variety of operational contexts within the Australian rail system. Operators of mechanised equipment must have undertaken training and, where appropriate, hold the relevant licence, permit or certificate and be recognised as competent for the class of machinery being used. No licensing, legislative or certification requirements apply to this unit at the time of publication. |
