DT Joining and assembly

Temporary joining

A process where components can be dismantled without being ruptured

Permanent joining

A process that is not designed to be reversed

Jigs and formers

Used to hold pieces of material together in order for them to be joined. By using this technique it is possible to exactly replicate the method of joining many times.

Brazing

A process often used to join two different metals together. The process involves melting a a third metal over, and into, the two pieces to be joined.

Soldering

Uses a lower melting-point alloy as its filler material.

Welding

The metals to be joined are heated to extreme temperatures, causing the components to melt. Once they have cooled and solidified, they are then joined together.

Riveting

A rivet is a permanent method of joining, where a small piece of metal is inserted into a hole in each of the components being joined. It is then deformed to an extent that it cannot be removed.

Pop rivet

A two-piece rivet and a special tool, called a rivet gun are used to fit them.

Wood joint

Used to join wood together, sometimes requiring adhesive the increase the strength.

Wood joints

Mortise and tenon, Dovetail, Comb (finger) joint, Butt joint, Mitre joint, Lap joint

Knock-down (KD) fittings

Fittings that help put furniture or a product together quickly and easily without using clamps or any glue.

Wood screw

Screws with a smooth shank below the head, they have a tapered point and are used in wood

Machine screw

Screws with threads up to the head. They do not taper and are designed to be used with nuts or threaded holes
