MEM05055 - Weld using oxy fuel gas welding process
Overview
This unit has been primarily developed for Engineering Tradesperson - Fabrication apprenticeship training and the recognition of trade-level skills in oxy fuel gas welding on heavy or light metal fabrications. It may also apply to other trade occupations requiring higher level oxy fuel gas 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
For Melbourne campuses
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 and safe work practices
-identifying and interpreting specifications from drawings, sketches and verbal or written job instructions for oxy fuel gas to AS 1554 General Purpose or equivalent
-selecting appropriate weld and joint preparation methods - setting up:
- gas cylinders
- hoses
- blowpipes
- tips and nozzles
- regulators
- flashback arrestors
- weld materials to AS 1554 General Purpose or equivalent using oxy fuel gas welding equipment while preventing distortion
- rectifying any defects completing weld records related to oxy fuel gas onto standard workplace forms.
