MEM05023 Weld using submerged arc welding process

Modification History

Release 1. Supersedes and is equivalent to MEM05023C Weld using submerged arc welding process

Application

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.

1.2	Comply with work health and safety (WHS) requirements at all times
1.3	Use appropriate personal protective equipment (PPE) in accordance with SOPs
1.4	Identify job requirements from specifications, sketches, job sheets or work instructions
2	Prepare materials for welding	2.1	Prepare materials to achieve the required weld requirements
2.2	Assemble/align materials to specifications, where required
3	Select, assemble and set up welding equipment and consumables	3.1	Identify and select welding machine settings and consumables from job requirements, welding procedures and specifications and/or technical drawings
3.2	Assemble and set up DC welding equipment
3.3	Undertake test runs and verify in accordance with specifications
4	Minimise and rectify distortion	4.1	Apply appropriate distortion prevention measures
4.2	Rectify any distortion using appropriate techniques
5	Weld joints using submerged arc by correct process	5.1	Deposit pad, butt and fillet welds in flat, and fillet welds in horizontal position, to specification
5.2	Clean joints to specifications using techniques and tools appropriate to the defect, material and process
6	Ensure weld conformance	6.1	Inspect weld joints visually for conformance to specifications
6.2	Rectify any weld defects with minimum loss of sound metal using correct techniques and tools
6.3	Maintain weld records, where required
