This unit of competency defines the skills and knowledge required to carry out submerged arc welding (SAW) where the welds are more likely to be associated with heavy rather than with light fabrication.

Weld quality would typically conform to AS 1554 General Purpose or equivalent.

Where the interpretation of technical drawings is required unit MEM09002 Interpret technical drawing 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.

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 submerged arc welding (SAW) process to AS 1554 General Purpose or equivalent; - selecting appropriate weld and joint preparation methods; - consistently weld materials to the specified standard or equivalent using DC welding machines and electrodes while preventing distortion; - rectifying any defects, and; - completing and maintaining weld records related to SAW welding 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) - main types of fluxes and flux/wire combinations; - typical applications of SAW and common materials; - application of weld metal transfer (short arc and spray); - material preparation; - joint preparations; - electrode classification; - causes of distortion for materials; - causes of defects and methods of rectification, and; - requirements of AS 1554 General Purpose or equivalent.
