Welding:
- Welding is a fabrication process that joins materials normally metals.
- This is often done by melting the workpieces and adding a filler material to form a pool of molten material that cools to become a strong joint, with pressure sometimes used in conjunction with the heat or by itself, to produce the weld.
- This is in contrast with soldering and brazing, which involve melting a lower-melting-point material to form a bond between them, without melting the work pieces.
- There are many different ways to weld, such as; Shielded Metal Arc Welding (SMAW), Gas Tungsten Arc Welding (GTAW), and Gas Metal Arc Welding (GMAW).
- Many different sources of energy can be used for welding, including a gas flame, an electrical arc, a laser, an Electron Beam (EB), Friction, and ultrasound.
- In the arc welding process, the source of heat is electricity (High ampere-low voltage).
- The required electrical energy for welding is obtained from an arc welding machine, a power source.
- A welding machine is specified by its Output ampere.
