Welding

4. two or more combined metals
7. These metals do not have any iron, such as titanium, nickel, lead, copper, bronze, brass and aluminum.
8. Small hammer blows stretch the surface of cold metals and reduce stress in the metal.
12. The amount of electrical voltage needed to create ionization of the materials, which either adds or removes electrons.Non-Ferrous
15. Gas that doesn’t combine chemically with metal.
16. The amount of amperes applied per square inch across a particular area.
19. An electrical current that forms in the gap between two electrodes creates an electric arc.
20. A hole is cut in one piece of metal. Another piece of metal is put behind the hole, and the weld is made in the hole to connect the two pieces of metal.

1. This cleans the metal used for welding
2. the area where materials are fused together
3. Largest type of metal in welds(typically an alloy)
5. The rapid cooling of metal using water, air or oil.
6. This welding tool controls gas for preheating the metal, as well as the oxygen for cutting the metal.
9. This means that gas pocket or inclusions are present in the welded material.
10. This is the metal that is added when making a weld.
11. the point where the metal welding is conjoined to the arc welding
13. The lowest temperature at which the metal or alloy turns liquid.
14. The metal surface is hardened using a heated flame, followed by a quick quench.
17. An electrode conducts the electrical current through a work piece to create the weld.
18. The width of a piece of metal removed by cutting.
