Application

This unit of competency been developed for engineering tradesperson - fabrication apprenticeship training and the recognition of trade-level skills in mark off/out of structural fabrications and shapes.

It applies to the marking off/out of general fabrications and shapes to specified measurements, tolerances and shapes using appropriate tools and equipment. Templates and patterns are produced as required.

Skills covered by this unit are generally applied in occupational and work situations associated with steel fabrication, boiler making or sheet metal work.

In a marine setting, it includes basic lofting/set out for construction of marine vessels and includes stem and transom development and use of tables of offsets that reflect chine and hull configuration. This includes lofting surfaces, straight edges, string lines, French curves and templates and marking out techniques apply to a range of materials and shapes.

Where more extensive lofting practices are required unit MEM09021 Interpret and produce drawings of curved 3-D shapes should also be selected.

Where marking out of general engineering components is required unit MEM12006 Mark off/out (general engineering) should also be selected.

Where the selection and use of tools is required unit MEM18001 Use hand tools and unit MEM18002 Use power tools/hand held operations, should also be selected as appropriate.

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

  • 6.2 Estimate quantities from drawing
  • 6.3 Minimise material wastage

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:

following work instructions, standard operating procedures (SOPs)and safe work practices

identifying and interpreting specifications and drawings for fabrication requirements, including materials, measurements and tolerances, joining methods, standards and code requirements

carrying out all marking off/out using appropriate marking out tools and equipment to specifications

calculating measurements not shown on drawings, as required

establishing and marking datum points

selecting appropriate template material and producing templates to specifications

storing templates, including labelling and identification, to procedures, as required

developing patterns by selecting and applying appropriate development and/or measurement sequence and determining correct allowances for fabrication and assembly and transferring these measurements

calculating allowances for fabrication and assembly, including shrinkage, thickness and inside/outside measurements, and transferring these measurements

identifying and estimating quantities of materials from drawings with minimise wastage.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

procedures for marking off/out and pattern development

tools and equipment to be used in the preparation of the marking off/out

datum points

materials that can be used for the preparation of templates and their application

manufacturing allowances that have to be considered when developing patterns

template labelling and identification procedures and storage requirements of templates

appropriate methods of development/marking off/out of a range of given objects

appropriate fabrication and assembly allowances

effects of material type and thickness on fabrication and assembly allowances

sources of data on fabrication and assembly allowances

relevant standards and codes and the meaning of symbols used

requirements of the codes/standards applicable to the work to be done

materials from which the component/assembly is to be manufactured

benefits of minimising material wastage.

Assessment Conditions

Assessors must:

have vocational competency in marking off/out structural fabrications and shapes at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires.

Assessment must include evidence of 160 hours of workplace practice associated with the skills of this unit in a functioning workplace.

All aspects of competent application of the unit must be addressed including prerequisite competency units and associated workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.

Knowledge assessment may be either verbal or written but must adequately reflect the knowledge requirements of the unit and its prerequisites in a functioning workplace.

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
