Vocabulary and Dictionary
Aesthetics
A set of principles of good taste and appreciation of beauty
Anvil
Formed from mild steel with hardened steel face welded on the top. The edges of the face may be progressively curved.
Anvil Stand
A cast iron support for the anvil. Presents the anvil at a comfortable and safe working height
Brazing
The process of joining two pieces of metal by fusing a layer of brass or spelter between the adjoining surfaces.
Cherry Red
The colour of the metal when heat is applied
Degrees Celsius
Temperature scale showing the references of freezing and boiling points of water Emery A fine abrasive powder found naturally in Greece and parts of Asia Minor
Emery Cloth
Paper or more often cloth , surfaced with emery powder, held by an adhesive; used for polishing and cleaning metal
Flux-borax
A substance added to a solid to increase its fusibility (easily melted). In soldering, brazing etc., added to the molten metal to dissolve infusible (not easily melted) oxide films which prevent adhesion
Helical
Having the form of a helix -a spiral curve like a corkscrew or a coiled curve like a watch spring Oxide Film A film created by the combination of oxygen with another element particularly at elevated temperatures
Residual Heat
The heat remaining in the material
Spelter Rod
A rod of copper and zinc alloy. Different spelter rods can be used where more than one fixing to a job is required.The greater the amount of zinc, the lower the temperature that is required to melt the rod. This enables more than one brazing process to take place on the same piece without damaging joints already established.
Knowledge
Materials and Components.
The physical and chemical changes which occur during forging and brazing. Temperature changes and the creation of oxide film.
Structures.
Using suitable methods of fixing, i.e. brazing, to ensure that
additional arms to the design are structurally safe and unlikely
to fracture when holding a lighted candle.
