Replace stellite tips

Assessment tool

Version 1.0
Issue Date: March 2024


This unit of competency describes the outcomes required to remove worn stellite tips from saw blades and to weld, anneal, clean and prepare replacement tips for grinding and return to service. Work is completed in a forest products factory setting.

The unit applies to Sawdoctor, Saw Repairer.

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

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