Difference Between Welding and Fabrication Services

Difference Between Welding and Fabrication Services

People usually get confused between welding and fabrication services. In this blog, we will discuss the difference between welding and fabrication services. Welding is a process that involves joining metal pieces together. Other materials like glass and thermoplastics are also included in welding but for the most part, people usually associate welding with metals. Whereas in the fabrication process, a large group of tasks is involved in making metal products. The fabrication process includes the whole manufacturing process from designing exact products to their final finish. Many metal fabricators are also trained, competent welders. Several welders also act as fabricators. Their role interchange varies as per the facility they work on and the specific job they are working on. One person can work primarily as a welder and can also take up other tasks like cutting, bending, shaping, and finishing the objects.

Based on the process:

Fabrication of any element involves a process that follows a linear and logical progression from start to end. The metal fabrication process begins with keeping the final product in mind. Whatever materials are being fabricated into objects have a definite purpose planned and described for. There are many steps that are involved in every fabrication process, and each one depends on the other for accomplishment. Followings are the main parts of the metal fabrication process:

Bidding: Every project starts with the work being offered or bid on. At this moment, the end-user will have an idea and scope of works framed-out that specifies what the result is for and the total number of units required. This step can be very detailed in some of the cases used in a highly complex industry like aerospace and can be a general concept used in a truck trailer.

Planning: This is a critical step in the fabrication process. Although there is not any hands-on practice going on yet for metal cutting, bending, and welding, the time and effort put into planning a design can make or break its success.

Production: To the real world, production is what shows the real work. After the customer selects the fabrication company through the competitive bid system and the plans are made, the production phase starts. This is where things get built. During production, raw materials take shape from typical stock and start to convert into a useful product.

Welding is a process having a single step that begins with a raw concept and ends with a complete product that is ready for installation and use. It is the process of joining metal-based materials together. The technique is called fusion. This is a complex process that involves using heat and pressure. There are many specialized tools and processes used in welding. Although welding is a single part of the metal fabrication process, still it is a highly skilled business that requires a lot of training and practice to master.

Mainly there are two welding processes that you will find in the metal fabrication industry. One is fusion welding, and the second is solid-state welding. Fusion welding includes heating metal parts and adding a filler to fuse them into a joined entity. Solid-state welding is a metal-joining concept but does not require a preservative. Here are some of the main welding processes you will find in the metal fabrication industry:

Shielded metal arc welding (SMAW): This is the best-known and most used welding form. It is a fusion method that involves an electric current and disposable welding rods that act as a filler between the surfaces being joined.

Oxy-acetylene welding (OA): Another common welding method is Oxy-acetylene welding which involves combining a tank of oxygen and a tank of acetylene with the help of a torch nozzle. This flame heats the metal and the filler rod allows metal fusion.

Tungsten inert gas welding (TIG): TIG welding is called the most refined method because of the high-quality results it gives. This is a “two-hand” technique which involves the use of a non-consumable tungsten electrode to create the weld.

Gas metal arc welding (MIG): This is a wire-feed welding method with a consumable rod supplied from a continuous spool of the electrode wire. MIG welding is outstanding for thin stock and sheet metal welds.

Welding methods do not end with these four processes as apart from these methods there are other methods too like submerged arc welding (SAW), which is done underwater. Another is exothermic welding (Thermite) which involves using extremely high heat supported by an aluminum-based charge to fuse metals.

Tools involved:

There is a difference in the tools utilized for welding and fabrication services. Usually, welders need some equipment such as vice grips, soapstone, vices, electrode holders, abrasives, chipping hammers, and welding clamps whereas fabrication professionals generally make use of wire cutters, throat fewer shears, angle grinder discs, and drill bits. Learning the main differences between fabrication and welding makes it easier to think that which service is needed for which task. In both instances, it is important to choose the correct specialist who will produce the perfect finished product.

Different Skill Set Requires:

Fabricators place the metal on the appropriate tool, and then gently deploy the tool to achieve the required task. Some fabricators also possess the capability to weld, the difficulty of the welding process often requires more focused consultants. Metal fabrication uses a wide array of metalworking techniques to make the components and structures essential for life in the modern world.

Welding has a very different strategy as compared to fabrication. Welders do require some immobile tools and they mainly perform the welding process itself by hand. Without extreme practice, a welder would not be able to make strong or neat welds. Creating a high-performance metal product, only a welder with certain years of experience can operate with the required degree of skill and precision.
