Weld rail on tram_light rail systems using submerged arc welding process

Assessment tool

Version 1.0
Issue Date: April 2024


Welds would mainly involve building up or pad welding on longer lengths of rail on tram/light rail systems. It covers welding both the rail head and the check rail. The weld quality is not measured against any Australian Standards.

This unit involves the skills and knowledge required to weld rail on tram/light rail systems using a submerged arc welding process.

It covers preparing materials, selecting and setting up welding equipment, carrying out submerged arc welding, inspecting for and correcting defects, and maintaining weld records.

Licensing or certification requirements are not 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)
