Did you know that welding has been practiced since ancient civilizations?
Welding is fusing two or more pieces of material with heat and pressure. It reduces the volume of the material but makes it more robust than the original parts.
Knowing how to weld is invaluable if you own a property like your home. However, should you accidentally cause a welding accident, you must find a professional to repair any damages.
In this article, we’ll tackle the different types of welding you need to know before taking on the welding task. Read on.
Gas Metal Arc Welding (GMAW)
Gas Metal Arc Welding (GMAW) is a welding process that uses a metal arc to join two or more pieces of metal together. The process creates an arc between the metal and a wire electrode, which then melts the metal and fuses it.
GMAW is popular because it is easy to learn and cost-effective. It is often used on thin and soft metals, making it ideal for many industrial, construction, and automotive applications.
Shielded Metal Arc Welding (SMAW)
Shielded Metal Arc Welding (SMAW) is a reliable and cost-effective welding process. It uses flux-coated consumable electrodes to convert electrical energy into a powerful arc, melting the base metal and forming a high-strength weld.
This basic welding method has been used since the early 19th century. It is the most common method for welding mild steel from base metals practiced by certified welding inspection companies.
Flux-Cored Arc Welding (FCAW)
Flux Cored Arc Welding (FCAW) is one of the most common welding services growing in popularity. It uses a specialized type of wire and flux-filled metal electrode to generate an electric arc that melts the joined metals.
FCAW eliminates the need for shielding gas as the flux core in the electrode melts and gives off a gas that forms a protective bubble over the weld. It is an ideal technique for novice welders and those who need to work in tight spaces or windy conditions.
Gas Tungsten Arc Welding (GTAW)
Gas Tungsten Arc Welding (GTAW) is a type of arc welding that utilizes a non-consumable tungsten electrode to form the arc, producing a high-quality, precise weld. It is often referred to as TIG welding, as it is one of the two most common methods, the other being SMAW.
GTAW is primarily used on thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. GTAW also has a high degree of versatility as it can be used on any material, including curved and out-of-position surfaces.
It is commonly used for projects such as surgical instruments, marine structures, and nuclear power plants.
Electroslag Welding (ESW)
Electroslag Welding (ESW) is a welding process that uses an electric arc between a bare, non-consumable electrode and a molten metal slag pool. This is possible by creating an externally applied electric current to produce a continuous weld.
This method is suited to welding metals such as steel and copper alloys. The melt-off of the metal slag creates the weld. aThis process requires removing the mill scale and surface impurities to ensure a clean, defect-free weld.
Different Types of Welding for Different Jobs
The different types of welding are capable of performing a variety of tasks in industrial and hobbyist projects. Whether a novice or a professional welder, you can find a method to suit your needs.
Try researching different types and uses of welding to gain a better understanding of each process. With the right tools, you can now create masterful welded joints!
