This unit covers preparing materials and routine gas metal arc welding (GMAW).  This unit applies in a maintenance or manufacturing environment where the weld quality is not required to meet an Australian Standard or equivalent. Fillet and butt welds would typically be performed on low carbon/mild steels.

Where welding is required to meet Australian Standard 1554 General Purpose or equivalent codes, occupational health and safety regulations and/or licensing requirements, Unit MEM05017D (Weld using gas metal arc welding process) should be selected.

Assessment

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each competency unit's learning outcomes and performance criteria requirements, including the setting of project and 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: - preparing materials; - setting up welding equipment; - welding with GMAW; - reading and interpreting routine information on written job instructions, specifications and standard operating procedures; - following oral instruction, and; - using measurement skills relating to joint preparation and routine GMAW.Students will also be expected to demonstrate the following knowledge: - different current and voltage settings, gas flow rates wire diameters, wire feed speed and other variables to suit typical situation; - material and equipment preparation; - properties and characteristics of materials and consumables; - equipment and equipment settings; - fuel gas properties and applications; - post-welding treatments; - weld characteristics; - safe welding practices, and; - use and application of personal protective equipment for routine GMAW.
