MAKE – 1c. Tools & Equipment (Joining)
Joining processes can be split into two techniques, permanent and temporary.
How do you join materials together?
When joining materials together that are hard (resistant) joints can be temporary or permanent.
Joints can be joined using adhesives (glues). Joints in wood can be joined using frame joints. Metal joints can be brazed or welded joints, or held together with fastening components such as screws, bolts, and rivets.
When joining paper or card you can also have permanent and temporary fixings. Fastenings such as stationary split pins/paper fasteners, paper clips and treasury tags. Not forgetting glues, tapes and staples.
How do you think foods and fabrics are stuck together?
No not together, that would be wrong and messy! Foods together and then fabrics together?
What are permanent fixings?
Permanent joints are meant, surprisingly to stay together. They could use of glues (adhesives), nails, rivets, or any of the heating processes of soldering, brazing or welding. Check out the PowerPoint on this page for what all of those mean.
What are temporary fixings?
Temporary fixings are designed to come apart and usually involve components with a screw thread. Examples of these are screws, nuts and bolts, or one of the many knock down fixings, those funny little blocks used in flat pack furniture.
Where would you use fixings?
Would you agree the majority of products are made from more than one piece of material?, well when the products are put together the pieces need to be joined. Can you hear that door opening?, well here come the fixings, for example joints in wood can be made with screws, nails, glues and knock-down fittings, or with wood joints such as butt joints, halving joints, mortice-and-tenon and dovetail.
While joints in metal can be made by soldering, brazing, welding or using rivets.
Finally joints in plastics can be made with special glues for plastic. Have you ever made one of those plastic models and used that really smelly glue? If you have you will know about joining in plastic.
Other fixings include rivets, bolts or machine screws not just screws.
