Release 1 . This is the first release of this unit of competency in the TLI Transport and Logistics Training Package.

This unit involves the skills and knowledge required to weld rail, crossings or switches on tram or light rail systems using an electric welding process in accordance with tram/light rail network standards, safeworking and regulatory requirements, and organisational procedures.

It includes preparing rails, crossings or switches for welding, gouging or grinding; setting up welding equipment; performing the welding operation; checking weld conformance; and completing required documentation.

This unit covers the processes used to repair rail surface defects and restore rail profile to plain rail, crossings and switches.

Welding equipment may include:

• electric welders
• electrode holder
• generators
• robotic welder
• wirefeed welding unit.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Not applicable.
