3 Overview This unit covers preparing materials, selecting and setting up the welding equipment, carrying out advanced manual metal arc welding (MMAW), inspecting for and correcting defects, and maintaining the weld records. This unit applies to welds associated with a range of structural sections and/or plate and/or pipe for general fabrication. All work and work practices must be undertaken to regulatory and legislative requirements. It is applicable in both a learning and assessment pathway and an assessment only pathway. This competence is performed in the context that all materials and equipment needed to carry out this function have been provided, including learning materials, learning programs and learning resources. Elements To achieve competency in this unit you must demonstrate your ability to: Prepare welding materials and equipment Weld joints to code requirements using MMAW 3. Assess weld quality and rectify faults. Pre requisite units of competence MEM05007 MEM05012 MEM05015 MEM05051 MEM05052 MEM09002 MEM12023 MEM18001 MEM18002 Perform manual heating and thermal cutting Perform routine manual metal arc welding Weld using manual metal arc welding process Select welding processes Apply safe welding practices Interpret technical drawing Perform engineering measurements Use hand tools Use power tools/hand held operations Manufacturing Skills Australia Page 3

4 Assessment In order to found competent in this unit you must competently complete all of the following Assessment tasks: Method of Assessment Task 1 Task 2 Task 3 Task 4 Task 5 Written Short Answer Questions Practical Observation Report Third Party/Supervisor Report Indirect Evidence Note: There are more assessment methods listed here than what is necessary to determine Competence.
