A Closer Look at Common Welding Methods

Welding methods are designed to help individuals join distinct pieces of metal together. You might be surprised to realize that almost every metallic or plastic equipment you see around you is welded. From your stainless steel coffee pot to your car, they all have some weld joints only that the methods employed might differ considerably. While there is a variety of welding methods used today, here are some commonly used methods.

Shielded Metal Arc Welding

This welding technique is among the most popular welding methods. It is mostly used in steel fabrication, pipeline works, and in repairing heavy machines. It is a particular type of arc welding that employs a welding electrode with a flux core, an electrode, and a current with high amperage. The consumable electrode creates the weld, while the flux rod protects the fresh from oxidation, which can compromise on the quality of the weld.

Gas Metal Arc Welding

This type of welding is commonly referred to as metal inert gas welding (MIG). This welding method uses a consumable electrode which is continually fed using a welding gun. Instead of relying on a fluxing agent to protect the weld, MIG welding employs an inert gas that is supplied to the welding area using the welding gun. The good thing about this welding method is that it can be used in a wide range of metals.

Gas Tungsten Arc Welding

This welding method is also known as tungsten inert gas (TIG) welding. Unlike other types of arc welding, this welding method does not use a consumable electrode. Instead, the welder uses an extra rod to forge the weld. This welding method is highly preferred in situations where strong weld bonds and weld quality are needed.

Flux Core Arc Welding

This makes this welding method ideal for jobs where speed and electrode efficiency are essential. Since there are a variety of electrodes used for MIG, welders are advised to ensure they choose the best fit depending on the nature of the project.

For any welding project, you need tools and skills job done. Some welding tips are easy to understand, but others that are only understood with experience. In light of this Welding Insider was created by David Hernandez to help people learn about the welding industry. Using such an online resource will undoubtedly improve your chances of becoming an accomplished welder.
