joining metal

• • Rivets – a mechanical fixing for joining two pieces of metal, can be decorative.
• • Nuts and bolts – a hole would be drilled in each piece of metal and the bolt fed through the hole. The nut is then tightened onto the bolt to hold the metal together.
• • Welding – where metal is melted at the joint of two pieces of metal together, doesn’t leave a neat finish
• • Soldering – solder is melted and flows between two pieces of metal to leave a neat, strong joint
• • Screws – can be self-tapping so cut their own thread as they are screwed into the metal or have pre-cut threads

• • Taps – cut an internal thread in a hole in metal
