Joining processes for timbers
Lesson details
Learning outcome
I can explain various mechanical and chemical methods to join different materials.
Key learning points
- Materials can be joined using mechanical fixings or components.
- Materials can be joined using substances that create chemical bonds between surfaces
Keywords
Mechanical fixings - parts that holds materials together using force
Chemical joining - using adhesives or heat to bond materials through a chemical reaction
Component - a ready-made part used across different products to make manufacturing easier
Common misconception
All joining methods work the same for every material.
Different materials need different joining methods based on their properties.
Teacher tip
Try to organise a small practical based on any of the processes mentioned in this lesson to fully embed learning.
