It may be hard to tell the difference between the metal fabrication and welding processes if you're not familiar with the industry. These services are interconnected, but knowing the distinctions of each can be helpful whether you're planning to build a custom shed or replace your metal roofing. The following guide offers an inside look at how welding stands apart from fabrication.

What’s the Difference Between Metal Fabrication & Welding?

Metal Fabrication

Fabrication incorporates a wide variety of metalworking techniques, one of which is welding. It is the umbrella term for everything from the design of a metal object to its production. It is used to create a wide variety of functional and ornamental items, including decorative fences, gates, auto parts, and medical machinery. 

It often includes the beginning phase of cutting, stamping, or stretching, followed by warping, spinning, or roll-forming. When metal is warped, it is bent with tools to fit new contours or angles. During spinning, a sheet is placed on a rotating machine and turned until it fits a preshaped mold. Roll-forming includes running long metal strips through a series of rolls that gradually contort the piece along a cross-section.

After the individual pieces of the structure or object are welded together, the metal is finished. This final touch uses polishing techniques to make a surface appear matte, shiny, or glossy. When metal is plated, it is coated in a thin layer of zinc, nickel, cadmium, or chromium, increasing its durability and reducing the risk of corrosion. The material can also be finished using black oxide. During this process, a chemical is applied that alters the surface of the product, turning it matte black.

Metal Welding

Metal welding uses high heat to melt and connect two pieces of metal, which join permanently once they harden. This is a common phase within the metal fabrication process, but it can also be used for glass or thermoplastics. 

There are a number of welding methods that professionals can use to complete a project, depending on the type of energy source or tools they use. Some of the most popular techniques are shielded metal arc welding, gas tungsten arc welding, and gas metal arc welding. This phase often takes place after the planning and design process, when assembling the piece or structure.
