Weld rail using flashbutt welding process

This unit involves the skills and knowledge required to weld rail using the flashbutt welding process in accordance with safeworking and regulatory requirements and workplace procedures. It includes performing pre-operational and post-operational equipment checks, preparing rail for welding, carrying out the flashbutt welding in accordance with workplace requirements, checking weld conformance, and completing all required documentation. Licensing or certification requirements may be applicable to this unit.

Application

Persons achieving competence in this unit will need to fulfil the applicable legislated rail safety requirements including acts and regulations from each state and territory together with any nationally approved compliance codes and/or guidelines.

Work is performed under some supervision, generally within a team environment. It involves the application of routine operational principles and procedures to weld rail using the flashbutt 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.
