Most people fail to understand the difference between welding and sheet metal fabrication and use them as interchangeable terms. But only a person familiar with the processes, like a Sheet metal manufacturer & fabricator in Faridabad, knows the exact differences.
If put in a simple language, sheet metal fabrication is a comprehensive process with a series of processes that turn flat sheets of aluminum and steel into products or structures. The series of processes include cutting, punching, welding, folding, assembling, and finishing.
If you have started working in any manufacturing industries in Faridabad and want to learn about the differences between the two processes, you’ve landed on the right page.
Before explaining the difference, let’s take a glance at the brief definitions of the processes.
WHAT IS SHEET METAL FABRICATION?
The Sheet metal fabrication Process includes a series of steps to turn flat sheets of metals (like aluminum and steel) into structures and products. With the process, the sheet metal fabricators in Faridabad can cut, bend, or stretch metal sheets to nearly any shape.
Here’s an explanation of each step involved in the fabrication process:
Designing: The primary step is to plan out the design of the products that need to be fabricated. The step is followed by all top sheet metal manufacturing companies in Noida. First, the basic diagrams are drawn, either by hand or with modern software like AutoCAD to ensure accuracy. For projects with complex parts needs, many fabricators prefer to create a prototype that gives them a better understanding of how to start the fabrication process.
Cutting: Several methods can be used to cut flat sheets of metals. The ones that are commonly used by sheet metal fabricators in Faridabad are water jet cutting, laser cutting, and mechanical shearing. Choosing the right method is imperative to ensure fewer chances of errors. One can choose the method based on the type of metal; the accuracy required, etc.
Forming: This involves folding, stamping, bending, punching, etc., to make the metal sheets adopt the right formation.
Assembling: Once the metal sheets are transformed into a form, they are assembled together to make the final products. Assembling is performed using screws, adhesives, welding, etc.
Finishing: In this step, the metal surface or products are given an aesthetic appeal by applying protective coatings like glazes, rust-resistance paint, or colors. The process boosts the look and working life of the metal parts. The parts can further be polished to give the outer surface a shiny appearance.
Installation: After the final making of the metal products or parts, they are installed with the help of the best expertise to ensure they deliver the expected performance.
Maintainance: Many sheet metal manufacturers & fabricators in Faridabad offer maintenance and repair services that include equipment cleaning, timely inspections, and repairs.
Different fabricators use different sets of the above processes to meet customers’ needs.

WHAT IS WELDING?
Welding refers to a process that connects two or more pieces of metals using heat and pressure. It falls under the category of sheet metal fabrication process.
The welding process is divided into two types:
- Fusion Welding: It involves heating metal parts and adding a filler to join them.
- Solid-state Welding: It involves joining metals without adhesives.
Different Welding Methods
- Shielded metal arc welding A common welding method, a.k.a. stick welding or fusion, involves using electric current and consumable welding rods as fillers to join two surfaces.
- Oxy-acetylene welding: It combines a tank of oxygen and acetylene with a torch nozzle. The flame heats the metal while a filler rod fuses the metal.
- Tungsten inert gas welding (TIG): Delivers high-quality results, owing to which is used by many sheet metal fabricators. It uses a non-consumable tungsten electrode to weld two or more parts.
- Gas metal arc welding (MIG): It is a wire-feed welding technique that involves the use of a consumable rod fed to form a steady spool of the electrode wire.

DIFFERENCE BETWEEN WELDING AND METAL FABRICATION
Both the processes are carried out using different techniques. Welding is a single process that is used to join two metal parts. On the contrary, sheet metal fabrication involves a series of processes to turn thin metal sheets into structures. Welding is a part of the fabrication process.
Set Of Tools
Sheet metal fabrication is a comprehensive process that involves the use of a specific set of tools. It starts with cutting the sheets into the desired shape and ends with giving a perfect surface finish to the metal structures. Sheet metal fabricators in Faridabad use tools like welds, grinders, sheet rollers, lathe machines, etc. Whereas welding is restricted to joining two metal parts, it involves using tools like consumable electrodes, welding clamps, safety gear, etc.
The processes must be carried out by professionals to ensure accuracy and reduce the risk of injuries. As fabrication is a comprehensive process, the person carrying it must know all the processes that fall under the category. On the other hand, a person carrying the fabrication process already knows of it as it is a part of the big picture.
THE NECESSARY GEAR TO CARRY THE PROCESSES
The processes are accompanied by certain risks to health and life, which can be avoided with the necessary gear, like:
- Auto-darkening helmet
- Eye protection
- Face shields and goggles
- High-visibility clothing
- Leather gloves and aprons
- Hearing protection
- Safety-toed footwear
A sheet metal fabricator must equip with all the necessary gear to work safely and reduce the risk of injuries.
Both the processes are important to deliver the necessary parts to different industries like automotive, food & beverage, pharmaceuticals, chemical, and others. Sheet metal fabrication and welding process have their unique importance in the manufacturing world, or we can say it is the sole of the manufacturing world.
