CADD-2 Welding
Welding Symbols and Terminology
Question | Answer |
---|---|
Welding | Method of joining parts by heating the metal to a high temperature, causing them to melt and fuse together. |
Groove Weld | Located in a notch of the material. |
Plug Weld | Fit into a small hole in the work material. |
Slot Weld | Similar to Plug except uses a slot instead of a hole. |
Gas Welding | Incorporates the use acetylene to create the heat for welding. |
Thermit Welding | Based on the natural chemical reaction of aluminum and oxygen. |
Fillet Weld | Fills material generally between two perpendicular pieces. |
Arc Welding | A form of fusion welding in which an electrical arc forms between the work and the electrode. |
TIG | Tungsten-Inert Gas welding. Provides the heat but requires a filler material. |
MIG | Metallic Inert Gas welding. The electrode contains a consumable metallic rod. |
Field Weld | Weld that is made on the job site. |
Spot Weld | Confined to a small area between electrodes. |
Seam Weld | Weld along the seam of two adjacent parts. |
Flash Welding | A special kind of resistance welding in which the parts to be welded have a very light air gap. |
Fusion Welding | Uses Heat to create the weld. |
Resistance Welding | Uses a combination of heat and pressure to make the weld. |
