Waterjet and Laser Cutting
Cutting metal is one of the most common applications of laser and waterjet cutting and is used on materials including stainless and mild steel, brass and aluminium. Lasers are ideal for cutting metal as they provide clean cuts with a smooth finish.
Waterjet cutting is a mechanical process where the material is removed by physical contact and material wear. The main difference with other cutting processes is the fact that it’s a cold-cutting process (non-thermal), meaning that no heat is used in the cutting process.
Waterjet cutting uses a high-pressure stream of water mixed with an abrasive material to cut a wide range of materials. A high-pressure water pump pressurises the water. This water flows through high-pressure tubing into the cutting head. In the cutting head, the water flows through a nozzle, turning it into an extremely fine stream. This stream cuts whatever material is placed in front of it.
Welding Process
Welding is a permanent joining process in which two pieces of metal join together to form one piece by heating the metals to their melting points. Additional metal, also called filler metal, is added during the heating process to help bond the two pieces together.
Types of Welding Processes
The following are types of welding processes according to the method of heat generated:
- MIG welding
- TIG welding
- Flux cord arc welding
- Plasma Arc welding
- Electron beam welding
- Laser beam welding
- Gas welding
