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

Laying out and marking off templates, structural sections and complex surface developments, and forming and shaping flat plate, sheet, solid bar, pipe and section materials 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 drawing, marking off, forming and shaping in the engineering fabrication field.

The credits allocated to this unit standard assume that a learner has already learned to lay out and mark off regular and irregular shapes for fabrication, and to form and shape sheet, plate, pipe and structural sections using power operated machines.

UNIT STANDARD RANGE

A general guide to the scope, context conditions, and level at which I am expected to perform.

The scope and level of this unit standard is determined by the ranges as indicated under the specific outcomes. Work is performed autonomously.

Laying out and marking off at this level should include composite problems containing one type of pattern development, triangulation from square, rectangle, circle and ellipse or parts thereof at inclined planes, and the intersection of two objects, the lofting and marking out of plate, structural details including column bases, truss apex, knee connections, truss feet and flanges.

Forming and shaping should include a range of operations. Forming may include both hot and cold techniques and use standard and non-standard hand and power operated machinery.

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.

PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD:

This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
