Weld using gas metal arc welding process (GMAW) GMAW undertaken autonomously or within a team environment using predetermined standards of quality, safety, work and welding procedures and the skills applied to a range of fabrication activities. A range of material suitable to heavy or light fabrication is used. Fillet and butt welds in all positions on a range of materials that may include carbon steel or stainless steel, etc. As a guide, welds produced to the standard of this unit would typically conform to Australian Standard 1554 General purpose, American Bureau of Shipping (ABS) or equivalent. Preparation of materials may include preheating, setting up of jigs, fixtures, clamps, etc. Remedial action using thermal processes may include oxyacetylene and air arc equipment. Grinding devices may also be used. Where thermal processes, hand andor power tools are required the appropriate specialisation units should be accessed.
