Solution

Brazing is the joining of two dissimilar materials using a third material. It is a method of joining pieces of metal by heating them at their interface with a flame, and using a non-ferrous (commonly brass) filler having a melting point below that of the metals being joined.

A drill bushing, also known as a jig bushing, is a tool used in metalworking jigs to guide cutting tools, most commonly drill bits.

Annealing is a heat process whereby a metal is heated to a specific temperature /colour and then allowed to cool slowly. This softens the metal which means it can be cut and shaped more easily.

metal inert gas (MIG) welding is a welding process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join.

galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting.
