The 2 Basic Types Of Welding: A Beginner's Guide
Posted on: 13 September 2021
Welding is a versatile and highly demanded metal fabrication process with a long history. Due to its many possible uses, welding services are needed across a wide variety of industries. Each industry and project type requires different welding techniques, knowledge, skills, and toolsets. The many types of welding within the welding services industry can be overwhelming for newer welders. However, welding can be distilled down to 2 popular and effective types, each with its own unique advantages and disadvantages. Here are the 2 basic types of welding.
MIG Welding
Also known as GMAW or Gas Metal Arc Welding, MIG welding is typically the fastest and easiest type of welding for beginners to learn. MIG welders allow for quick jobs and can be used on a wide variety of materials and thicknesses. MIG welders operate by feeding a consumable wire of filler metal through the wand. This filler metal also acts as the electrode by creating the welding arc. The wand also expels gas to shield the metal from outside contamination. This means that MIG welding is less ideal outside, where conditions are less predictable, and potential contaminants are more plentiful.
Due to their simple mechanisms, MIG welders are relatively inexpensive to purchase and maintain. MIG welders are versatile but lack fine precision. For this reason, they are often used in the creation of buildings and homes. These welders are also used in the auto industry for simple repairs that don't require fine control.
TIG Welding
Also known as GTAW or Gas Tungsten Arc Welding, TIG welding is more difficult to learn than MIG welding. TIG welders complete jobs at a slower pace than MIG welders and are typically recommended for specialized jobs that involve welding thinner materials. TIG welding uses a non-consumable tungsten electrode to create the welding arc and is one of the few forms of welding that can be performed with no filler metal. In addition, TIG welders possess heating controls, allowing for fine control of the weld. This fine control is an incredibly beneficial trait for use in the aerospace industry, where precision is extremely important for ensuring structural integrity and passenger safety. For this reason, TIG welders are recommended for more experienced welders and are also more expensive than MIG welders.
Conclusion
Welding is a complex and versatile skill set that transcends a wide variety of industries. Hopefully, you now have a better idea of the 2 basic types of welding and how they can benefit you. If you'd like to learn more about your welding options, contact a welding service, such as Acutech, today.
