A Look at the Different Types of Welds

When we talk about welding, it’s actually a widely encompassing term that covers several different processes. Some of the most common types of welding include gas metal arc welding, tungsten inert gas welding, standard arc welding and standard gas welding. To help you understand these various processes a little better – and their connection to aluminum – let’s break down the basics of each type.


Welding

Gas Metal Arc Welding

Let’s start with gas metal arc welding, otherwise known as GMAW or MIG welding. The process is most commonly used when working with materials like aluminum and stainless steel. Unlike some other types of welding, this one is comparatively accessible. It is widely used in various industries and even at home by amateur welders due to the fact that it is both easy to learn and master.

Tungsten Inert Gas Welding

Tungsten inert gas welding, or TIG welding, is a process that requires more training and expertise than MIG. That’s because working with inert case welding typically means the job involves some type of superior standard of finishing. This is involved work, and operators need to take great care to get it right. Unlike other types of welds, there is typically no sanding required at the end of a MIG project.

Arc Welding

Another basic welding process is arc welding, also known as SMAW. You will find this process used throughout most industries that work with heavy metal. From manufacturing to repairs, this welding method is also fairly simple and easily teachable. If the metal involved in the work is greater than 4 millimeters thick, arc welding is typically used.

Gas Welding

Finally, there is gas or oxy-acetylene welding, a generally rarer type of welding. This process involves mixing gas and oxygen together to melt and weld several different types of metal. In most cases, this welding technique is used when working with bronze and copper, though it is also used on certain types of aluminum.

No matter what type of welding style is used, this is a complicated job that is invaluable in countless industries.
