Aboriginal Cultural Standards Framework: Cultural Responsiveness Standard - Staff embed Aboriginal cultural knowledge, such as traditional welding-like joining methods 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 welding and joining techniques to understand Indigenous innovation and adaptation in material use.

Reading: Basic Welding Techniques

Welding is a process of joining metals by melting them together using heat. Common types include arc welding, MIG, and TIG welding. Arc welding uses an electric arc to melt metals, suitable for thick materials. MIG welding employs a wire electrode and gas shield, ideal for beginners and quick joints. TIG welding offers precision with a tungsten electrode, used for thin metals and high-quality welds. Safety is crucial, requiring helmets, gloves, and ventilation to protect from sparks, fumes, and UV light. Welding applications range from construction to artistic sculptures. Proper technique ensures strong, durable joints.

Indigenous peoples in Kimberley and Pilbara used fire and natural binders for joining materials, similar to welding principles, fostering resourcefulness and environmental respect. Year 7 students explore these techniques, blending cultural insights with modern practices for innovative design. Mastering basics builds foundation for advanced metalwork. (Word count: 350)
