In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
Performing mechanical cutting, drilling, punching, assembling and joining operations using hand tools, power tools and machines as used in the fabrication industry.

The skills, values and knowledge reflected in this unit standard are required by people in the field of engineering fabrication, which includes boilermaking, sheetmetal working, welding and vehicle body building. The learning outcomes in this unit standard contribute to the exit level outcomes required for the National Certificate in Fabrication (Light / Heavy) (NQF level 4) and related qualifications. 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
This unit standard has been designed as part of a progression. It is one of a series of unit standards for cutting, drilling, punching, assembling and mechanically joining metals in engineering fabrication.

The credits allocated to this unit standard assume that a learner has already learned to mechanically cut, drill and punch fabrication materials using powered machinery and to assemble and mechanically join sheet, plate, tube, pipe and steel sections. 

UNIT STANDARD RANGE

    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    My assessment will be governed by the policies and guidelines of the MERSETA ETQA, which has the jurisdiction over this field of learning. My assessor will (at the very least) be accredited and have a technical qualification in this learning area.

    I can be assessed in the language of my choice although if I have to report incidents or conditions to someone else, I will be assessed on my ability to report in the language commonly used in my working environment.

    I will be assessed in the workplace but I can submit documents, projects, test results and assignments that were produced outside of the workplace.

    I can be assessed against this unit standard to obtain credits, or as part of an integrated assessment for a qualification.
