4 Welding Methods Used In Custom Sheet Metal Fabrication

4 Welding Methods Used In Custom Sheet Metal Fabrication

Custom sheet metal fabrication is the process of transforming flat sheets of metal into customized structures or components. It involves processes like cutting, bending, and shaping the metal to create unique designs. One of the key aspects of custom sheet metal fabrication is its ability to cater to individual needs and preferences. Common metals include steel, aluminum, stainless steel, brass, and copper. Each material has its own set of properties and characteristics that make it suitable for different applications.


Precision plays a crucial role in custom sheet metal fabrication as every cut, bend, and weld must be done meticulously. Advanced tools such as laser cutters and welding machines are employed for precise results. We are here to discuss more about the latter.


Common welding methods used in custom sheet metal fabrication



TIG (Tungsten Inert Gas) welding method uses a non-consumable tungsten electrode along with an inert gas shield to produce high-quality welds with excellent aesthetic appeal. It is commonly used when precision and cleanliness are paramount.



WIG (Wire Inert Gas) welding method utilizes a continuous wire electrode fed through a hand-held torch while being protected by an inert gas shield. This method provides higher productivity and deposition rates compared to TIG welding.



FACW (Flux-cored Arc Welding) technique involves using a tubular wire filled with flux instead of solid wire electrodes. This method offers better penetration and higher deposition rates than other traditional arc-welding processes.



STICK (Shielded Metal Arc Welding) technique employs an electric current flowing between a coated electrode rod and the workpiece. It creates strong welds suitable for thicker materials. However, it may require additional cleaning after completion due to slag residue left behind.


Welding serves as the backbone of custom sheet metal fabrication by providing strength, structural stability, and limitless design possibilities.
