Joining processes for metals

Design and technology

In this unit pupils will develop technical principles knowledge with an explicit focus on exam technique.

A ready-made part used across different products to make manufacturing easier is called a {{}}.

Which statement best defines a mechanical fixing?

adhesive works equally well on all materials

Which statement is correct about joining methods and materials?

join sheet metals with a hollow rivet and gun

hammered pin creates a permanent metal joint

threaded fasteners for strong, removable joints

threaded fixings that cut into material for grip

deforming metal to secure wires or thin parts together

Match the mechanical fixing to the correct description.

low heat process using a filler metal to join metals

higher heat filler metal with silver for strong joints

electric arc melts metals and filler to fuse them

clamps sheets and melts points with electric current

Match the chemical joining/heat joining process to its correct description:

physical properties/characteristics relate to how a material looks and feels

working/mechanical properties describe material behaviour when exposed to forces

hardness is a physical property/characteristic

elasticity is a working/mechanical property

Which of the following statements is **incorrect**?

it can maintain its shape under normal conditions without breaking

it can resist environmental changes like temperature and moisture

the cost-effectiveness of building a structure

What does 'structural integrity' refer to in materials and structures?

they are always made from recycled materials

they're easier to transport, store and use in different manufacturing processes

they don't require specialised tools to work with

What is one main benefit of using standard stock forms in manufacturing?

Shaping materials again without changing its basic chemical structure is called {{}}.

Which property would be **most** important when choosing a material for a flexible, stretchable item like a bungee cord?
