MEM05017D - Weld using gas metal arc welding process

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: - identifying and interpreting welding specifications including appropriate standards e.g. Australian Standard 1554 General Purpose, American Bureau of Shipping (ABS) or equivalent; - selecting and using appropriate tools and equipment; - using a variety of welding machines and electrodes; - identifying and rectifying weld defects; - applying techniques for distortion prevention and rectification; - cleaning welds; - reading and interpreting information on sketches, written job instructions, specifications, standard operating procedures and engineering drawings; - recording routine information including routine weld records related to GMAW onto proformas and standard workplace forms; - following oral instructions, and; - measurement skills relating to joint preparation and GMAW. Students will also be expected to demonstrate the following knowledge: - types of gases and their uses; - the relationships between amperage/wire feed, voltage, gas flow, electrode and material; - the application of weld metal transfer (short arc, spray etc.); - correct welding machine, leads, hand pieces and electrodes; - material preparation; - joint preparations; - electrode classification; - causes of distortion for materials within the scope of this unit; - safe welding practices, and; - use and application of personal protective equipment for GMAW.
