This unit of competency has been developed for Engineering Tradesperson - Fabrication apprenticeship training and the recognition of trade-level skills in manual metal arc welding (MMAW) on heavy or light metal fabrications. It may also apply to other trade occupations requiring higher level MMAW welding skills.

Weld quality would typically conform to AS 1554 General Purpose, and American Bureau of Shipping (ABS) or equivalent.

Where manual thermal processes associated with preparation, pre-heat and/or post-heat is required unit MEM05007 Perform manual heating and thermal cutting and unit MEM05008 Perform advanced manual thermal cutting, gouging and shaping, should also be selected as appropriate.

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

Assessment

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit's learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines. Students will be expected to demonstrate the following required skills: - following work instructions, standard operating procedures (SOPs)and safe work practices; - identifying and interpreting specifications from drawings, sketches and verbal or written job instructions for welding using manual metal arc welding process (MMAW) to the specified standard; - selecting appropriate weld and joint preparation methods; - consistently weld a range of materials to the specified standard or equivalent using AC or DC welding machines and electrodes while preventing distortion; - rectifying any defects, and; - completing weld records related to MMAW onto standard workplace forms.Students will also be expected to demonstrate the following knowledge: - safe welding practices and procedures and use of personal protective equipment (PPE); - material preparation for MMAW; - weld joint preparations; - welding electrode classification; - causes of distortion for materials when welded; - causes of weld defects and methods of rectification; - relationships between amperage, electrode and material, and; - standards for MMAW, including AS 1554 General Purpose any other equivalent standards.
