Description
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.Band: AUnit Weight: 4
