Welding: Welding is a non-detachable fusion or filling of two or more materials of same or different types by applying heat, pressure or both with or without using an auxiliary metal.
- Some welding operations are performed only by heat without using any pressure.
- Some welding operations are performed both by heat and pressure.
- Some welding operations are performed only by pressure without using any external heat.
- The operation is performed either by fusing the parts together or by applying a filling between them with a welding rod.
- Fusing operations are performed with or without utilization of a welding rod.
- There are different methods of welding to fuse materials of similar (steel and steel) or different types (stainless steel and aluminum) together.
In general, welding methods and types are listed like below;
- Electrical arc welding
- Inert gas welding
- Oxyacetylene welding
- Electric resistance welding
- Energy beam welding
- Solid-state welding
