ACTDEP024: Critique needs or opportunities for designing, and investigate materials, components, tools, equipment and processes to achieve intended designed solutions.
ACTDEP035: The nature of materials and their properties in design and technologies, such as metals in metalwork.
ACTDEP037: Select and justify choices of materials, components, tools, equipment and techniques to effectively and safely make designed solutions.
Aboriginal Cultural Standards Framework: Cultural Responsiveness Standard - Staff embed Aboriginal cultural knowledge, such as traditional soldering-like and brazing techniques in the Kimberley and Pilbara regions, to demonstrate respect for community values and environmental stewardship.
Cross-Curriculum Priority: Aboriginal and Torres Strait Islander Histories and Cultures - Students explore pre-contact and contemporary indigenous joining techniques like soldering and brazing to understand Indigenous innovation and adaptation in material use.
Soldering and brazing are joining techniques using filler metals, but differ in temperatures and applications. Soldering uses low temperatures below 450°C, ideal for electronics and delicate parts, with filler like tin-lead alloys. Brazing operates above 450°C but below base metal melting point, creating stronger joints for plumbing and metalwork, using brass or copper filler. Soldering is easier for beginners, requiring less heat, while brazing needs more skill but offers durability. Safety includes ventilation for fumes and protective gear for both. These methods enable complex designs in metalwork.
Indigenous communities in Kimberley and Pilbara used natural adhesives for joining, similar to soldering, promoting harmony with nature. Year 7 students compare these techniques, integrating cultural awareness for sustainable design. Understanding differences helps select appropriate methods for projects. (Word count: 350)
