Description
This unit of competency has been developed for Engineering Tradesperson - Fabrication apprenticeship training and the recognition of trade-level skills in gas tungsten arc welding (GTAW) on heavy or light metal fabrications. It may also apply to other trade occupations requiring higher level GTAW 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.Band: AUnit Weight: 4
