Types of Welding and Cutting Processes
There are various welding and cutting processes used in industries, each serving unique purposes.
Welding Processes
-
Shielded Metal Arc Welding (SMAW)
SMAW also known as manual arc welding (MMA or MIG/MAG process when used semi-automatically), is a process that is used to produce a steady, stable arc between a continuous wire feed (electrode) and the material (workpiece) that is being welded. This process is used for general fabrication where a variety of ferrous and non-ferrous materials are welded.
-
Gas Metal Arc Welding (GMAW)
This process was introduced in the early 1950s. This process is also known as the MIG (Metal Inert Gas) process. In this process, an arc is formed between the electrode wire and the base material. An inert gas, like argon, protects the arc and the material being welded from atmospheric gases. The GMAW process can be used for both ferrous and non-ferrous materials and requires a shielded arc to prevent atmospheric gases from disturbing the weld pool.
Cutting Processes
-
Flame Cutting Process
The flame cutting process is used to cut metal plates and tubes. Oxygen fuel gas (Oxy-acetylene) is used together with an air jet of nitrogen. The flame cutting process is highly precise, with the ability to cut curves with ease, making it ideal for various metal fabrication tasks. Cutting thick materials is often done at a slower rate to allow the high temperature gas flames to penetrate the metal.
-
Plasma Cutting Process
Plasma cutting uses a high-speed jet of ionized gas (plasma) to cut materials. The plasma cutting process cuts through metal by using an electric arc to ionize the gas in the air. A shield gas, like argon, is used to prevent the plasma arc from being extinguished by atmospheric gases. This process offers high precision, faster cutting speeds, and lower production costs.
In conclusion, a welding and cutting machine is a complex device with multiple components, requiring precise understanding and maintenance. Each process has its unique characteristics and offers distinct benefits. This foundation of welding and cutting machine fundamentals provides a base for future knowledge on advanced processes, equipment maintenance, and application techniques.
