Chapter 2 - Joining Processes

Question 1

Filler rod

Answer 1

A material that is used to help create the joint between two materials. For example, a solder filler rod is used when joining copper pipe together

Question 2

Temporary joining method

Answer 2

One where the components can be joined and separated without damage to the material. E.g. a nut and bolt assembly.

Question 3

Permanent joining method

Answer 3

One where separation of the component parts results in damage to the materials. E.g. a welded joint

Question 4

Wood joints

Answer 4

The general name given to the more traditional forms of joining woods. E.g. mortise and tenon joint, dovetail joint, finger/comb joint, bridle joint, etc.

Question 5

Self-tapping screws

Answer 5

Used for forming their own threads in materials. They can be used to join metals and plastics. Can also be used with various forms of captive nut, e.g. assembly of car interiors.

Question 6

Adhesive

Answer 6

Chemicals used to bond materials together. Different adhesives can be used to bond specific materials.

Question 7

Wood screw

Answer 7

A form of screw designed for use specifically with wood. The two materials are held together by the shape of the screw thread that the screw forms in the material as it is being inserted.

Question 8

Knock-down fittings (KD)

Answer 8

These come in a variety of guises, each type intended for a particular application. Used extensively (but not exclusively) with self-assembly furniture.

Question 9

Spot Welding

Answer 9

A form of resistance welding where the metal components being joined are clamped between two electrodes. An electric current is passed between the electrodes, causing a build-up of heat at the centre of the joint, fusing the two components together. E.g. in assembly of car body panels.
