- 1WeldingA joining process that produces coalescence (i.e. growing together) of materials by
heating them to the welding temperature, with or without the application of pressure or by the
application of pressure alone, and with or without the use of filler material - 27 groups of welding process1. Arc Welding (AW)
2. Solid State Welding (SSW)
3. Resistance Welding (RW)
4. Oxyfuel Gas Welding (OFW)
5. Soldering (S)
6. Brazing (B)
7. Other Welding - 3Positive terminal of electrical circuit is called _____Anode
- 4Negative terminal of electrode is called the ________Cathode
- 5What Happens When an Arc is Created?Electrons are emitted from Cathode and transferred to Anode through
ionized gas inbetween - 6How Hot Can a Welding Arc Get?30,000 Celsius
- 7Two Power Source Classifications1. Constant Current
2. Constant Voltage - 8Gas Tungsten Arc Welding (GTAW)Arc is established between tungsten electrode and the work piece
- 9Types of Shielding Gas1. Argon
2. Helium
3. Mix of the Two - 10Autogenous WeldWhen no filler metal is added to the weld
