Reading: Joining Methods: Riveting, Welding, Brazing

Joining methods include riveting, welding, and brazing for metal assembly. Riveting uses rivets to fasten parts together. Welding melts metals to fuse them. Brazing uses filler metal at lower temperatures. Safety is crucial with protective equipment.

These methods create strong bonds for design projects. Indigenous practices use similar joining for tools. Year 7 students learn safe joining techniques. Proper use ensures durability.

Joining supports complex designs in technology.

In riveting, a rivet—a small metal pin—is inserted through aligned holes in two pieces of metal. The end is then hammered or pressed to flatten it, creating a permanent joint. This method is common in aircraft and bridges for its strength and reliability without heat.

Welding involves heating metals to their melting point using tools like arc welders or gas torches. The molten edges fuse as they cool, forming a seamless bond. It's ideal for heavy-duty structures but requires ventilation to avoid harmful fumes.

Brazing, unlike welding, doesn't melt the base metals. Instead, a filler metal (like brass) with a lower melting point is heated to flow between parts, bonding them upon cooling. It's useful for delicate work, such as jewelry or pipes, and preserves material properties.

Always prioritize safety: wear gloves, goggles, and aprons to protect against sparks, heat, and splatter. Indigenous Australians historically joined metals for tools using natural resins or heat, inspiring sustainable modern practices. Mastering these techniques empowers creative, durable metalwork projects.
