Welding Methods Involved In Custom Sheet Metal Fabrication

December 28, 2022

Welding is a process of joining two pieces of metal together by melting and fusing them. It is an essential part of custom sheet metal fabrication, as it allows for the creation of strong and durable structures. There are various welding techniques that can be used in custom sheet metal fabrication.


Common welding techniques used in custom sheet metal fabrication


Gas tungsten arc welding (GTAW):

GTAW is a versatile welding technique that can be used on a variety of metals, including aluminum and stainless steel. It is also relatively easy to learn and use, making it a popular choice among welders. However, GTAW does have some drawbacks. For instance, it is a slow welding process, which can increase production costs.


Flux-cored arc welding (FCAW):

Another popular welding technique used in custom sheet metal fabrication is flux-cored arc welding (FCAW). FCAW is similar to GTAW in that it uses an electrode to create an arc between two pieces of metal. However, instead of using shielding gas, FCAW uses a flux-cored wire that helps to protect the weld from contamination. This makes FCAW ideal for use in dirty or hazardous environments where shielding gas could be blown away by wind or other factors.


MIG (metal inert gas):

This is a type of arc welding that uses a wire electrode that is fed through a welding gun and into the weld pool. The heat from the electric arc melts the wire and the base metal, and they fuse to create a strong joint. MIG welding is commonly used for thicker metals, as it can create strong welds quickly.


TIG (tungsten inert gas):

TIG welding is a type of arc welding that uses a tungsten electrode to create an electric arc. The heat from the arc melts the metal, and the welder can use filler material to add strength to the joint if needed. TIG welding is commonly used for thinner metals, as it allows for more precise welds.
