| 1. AIR-ARC CUTTING | A. An arc welding process in which fusion is produced by heating with an electric arc between a metal electrode and the work. Shielding is obtained from an inert gas such as helium or argon. Pressure and/or filler metal may or my not be used. | |
| 2. BARE METAL-ARC WELDING | B. An arc cutting process in which metals to be cut are melted by the heat of the carbon arc. | |
| 3. CORNER JOINT | C. A device designed for checking the shape and size of welds. | |
| 4. FILLER METAL | D. A joint between two members located approximately at right angles to each other in the form of an L. | |
| 5. GAS METAL-ARC (MIG) WELDING (GMAW) | E. An arc welding process in which protection from the atmosphere is obtained through use of a flux, decomposition of the electrode covering, or an inert gas. | |
| 6. WELD GAUGE | F. Any welding process or method in which pressure is used to complete the weld. | |
| 7. SHIELDED WELDING | G. The metal particles expelled during arc and gas welding which do not form a part of the weld. | |
| 8. PRESSURE WELDING | H. Metal to be added in making a weld. | |
| 9. SPATTER | I. That portion of a weld that has been melted during welding. | |
| 10. WELD METAL | J. An arc welding process in which fusion is obtained by heating with an unshielded arc between a bare or lightly coated electrode and the work. Pressure is not used and filler metal is obtained from the electrode. |

TYPES OF WELDING
Welding is a process of joining together metallic parts by heating the place of contact to the fusion state1.
Welding processes are classified according to the source of energy employed for heating, the metals and the state of the metal at the place of welding.
There are different types of welding such as hammer welding,2 thermit welding3, electric arc welding, gas welding, etc.
Hammer welding is a process in which two heated metal parts are joined and fused together by force4 from a power hammer.
Thermit welding is a process consisting of a chemical reaction. It is used in repairing large sections such as rails, frames, etc.
In arc welding the workpieces5 are not melted by a flame. They are melted by an electric arc. In order to create the arc, a powerful electric current must be provided. The current must be at least 60A, otherwise the arc will not create enough heat.

In gas welding, it is necessary to use a mixture of two gases. To create a hot flame, a combustible gas must be mixed with oxygen.
Gas welding is normally used to join steel to steel.
