Weld rail using electric welding process

Assessment tool

Version 1.0
Issue Date: May 2024


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 the welding of 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.

This unit involves the skills and knowledge required to weld rails, crossings or switches using an electric welding process in accordance with approved standards, safeworking and regulatory requirements and workplace procedures. It includes preparing rails, crossings or switches for welding; setting up welding equipment; performing the welding operation; 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. Licensing or certification requirements may be applicable to this unit.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
