Application
This unit of competency defines the skills and knowledge required to perform complex metal spinning operations (excluding computer numerically controlled [CNC]) operations, using advanced processes, spinning tools and accessories.
Where there is a requirement to join spun materials or products in addition to, or instead of, (the spinning operation of) swaging, the following units should also be selected as appropriate:
MEM05003 Perform soft soldering
MEM05006 Perform brazing and/or silver soldering; or
MEM05004 Perform routine oxy fuel gas welding; or
MEM05012 Perform routine manual metal arc welding
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Band: A
Unit Weight: 4
