Custom Fabrication: An Overview

Custom fabrication is a game-changer in the world of manufacturing, enabling the creation of customized, high-quality products that cater to specific requirements. From expansive aluminum walkways for municipal water treatment facilities to large quantities of repetitive items like handrails and stairways for industrial facilities.

For over three decades, custom fabrication has revolutionized the way products are made, using welding equipment and other specialized tools to produce superior-quality workmanship. The craftsmanship and dedication in custom fabrication are what differentiate it from mass production, ensuring that every project is completed to the highest standards, with quality, fairness, and integrity as the utmost priority.

Custom Fabrication Techniques

Custom fabrication is an art form, combining various techniques such as welding, metal cutting, and forming/machining to create masterpieces. Investing in experienced craftsmen and state-of-the-art welding equipment provides a competitive advantage, ensuring the best possible outcome for every project. One of the essential tools in this process is welding positioners, which assist welders in positioning weldments for optimal comfort and efficiency, reducing fatigue and expediting work.

Industrial welding automation is another aspect of custom fabrication, employing equipment with specific functions designed for a particular method or product. These advanced tools not only speed up the process, but also guarantee increased productivity, quality, profitability, and finish.


Welding is the backbone of custom fabrication, utilizing various methods such as MIG, TIG, and gas welding to join or separate metals. Arc welding is especially suitable for repair works and fabrication of structural steel. It can be used on a variety of heavy metals. Resistance welding is another efficient process, ideal for mass production of automobiles and making multiple spot welds in one go when joining large parts, due to its high speed.

Each welding technique has its own unique set of features, such as the inert gases and electrodes employed in TIG welding, which produces higher quality and stronger welds, as well as a superior finish with minimal post-weld cleaning. Custom fabrication projects typically utilize various types of welding equipment, such as oxy-acetylene welders, stick welders, TIG welders, and MIG welders, ensuring the perfect weld for every project.

Metal Cutting

In addition to welding, metal cutting plays a crucial role in custom fabrication, shaping and resizing raw materials to create the desired form. Techniques like sawing, shearing, chiseling, grinding, and milling are used to remove excess material from a workpiece, while plasma and laser cutting offer enhanced precision and accuracy, quicker cutting speeds, and improved safety.

Safety is of utmost importance in metal cutting, and it is crucial to wear proper protective gear, ensure proper ventilation, and follow all safety protocols when working with welding equipment and other potentially hazardous tools. With the right safety measures in place, custom fabrication professionals can create stunning products without compromising their well-being.

Forming and Machining

Forming and machining processes complement welding structural steel and metal cutting in custom fabrication, providing additional methods for shaping and refining products. Forming involves altering the shape of a partially completed product, such as sheet metal, through plastic deformation, while machining removes material from a workpiece using a cutting tool to create precise shapes and sizes.

These processes, along with welding and metal cutting, form the foundation of custom fabrication, allowing for the creation of intricate and specialized products tailored to specific customer requirements. With a diverse set of techniques at their disposal, custom fabrication professionals can craft virtually anything imaginable.

Custom Fabrication and Welding FAQs

What is the meaning of custom fabrication?

Custom fabrication is the creation of custom-made materials through multi-stage assembly work for a particular purpose. It involves detailed planning and accurate fixturing.

What are the 4 main types of welding?

The four main types of welding are: Gas Metal Arc Welding (GMAW/MIG), Gas Tungsten Arc Welding (GTAW/TIG), Shielded Metal Arc Welding (SMAW), and Flux Cored Arc Welding (FCAW).

Each welding process involves a different combination of equipment, technique, and materials to achieve the desired result.

What is the hardest welding to do?

Gas tungsten arc welding (GTAW) or TIG welding is the hardest form of welding to learn, due to its slow process and the need for a foot pedal to feed the electrode and control the variable amperage while maintaining a steady hand at the welding torch.

At the same time, it is also the most versatile form of welding, as it can be used on a variety of metals, including aluminum, stainless steel, structural steel, and titanium. It is also the most precise form of welding, as it allows for very precise control of the weld puddle.

What techniques are employed in custom fabrication?

Custom fabrication employs welding, metal cutting and forming/machining, utilizing specialized tools and welding equipment. These processes are used to create custom parts and components for a variety of industries, from automotive to aerospace. They are also used to repair and maintain existing structures and equipment.
