Fabrication is typically defined as a set of manufacturing processes that take raw stock material and turn it into a part that would be used in another manufacturing process such as assembly. The following are some of the common types of metal fabrication processes:
Machining a piece of material is a phenomenal technique to add value to the piece through the removal of some of its volumes. The developments in machining practices and technologies have made it possible for the manufacturers to achieve designs that were difficult to achieve in the past. The resultant component alterations and tolerances that were only achievable with the most advanced facilities can now be obtained using common equipment.
The development of advanced machining technologies offers companies an opportunity to develop new forms of added value and bring to the market more specialized products.
Welding is when a combination of heat and pressure is used to join together two or more pieces of metal. It is a popular fabrication process across industries. MIG, TIG, arc and flux cored arc are four of the most popular types of welding. The parts used in a welding process can be bars, panels or sheets. There are numerous welding technologies and techniques. Industries like automotive employ the most advanced welding tools such as robotic welding units to produce high-end parts.
Cutting is another common type of metal fabrication service. It is used to cut metal workpieces to split into different sections. While traditional cutting methods are still being used in many industries, progressive manufacturing facilities used advanced cutting tools like laser and waterjet cutting. In lengthy fabrication processes, cutting is probably the first stage. Die cutting is another metal cutting technique that utilizes a die to cut metal.
Punching is a process of forming holes in a piece of metal. Metal is placed under a die and submitted to a punch-through by a drill to form the hole. It’s important that the circumference of the drill slot fits correctly through the die in order to achieve the right size of punch. There are subcategories of a punching process. In most punching applications, holes are formed into a panel of metal to fasten other foreign objects.
Forging is a fabrication process that uses force to shape metal. A die or hammer strikes the metal workpiece until the intended shape is achieved. Forging can be done with metal heated to different levels of temperature. Blacksmiths have been using forging for centuries.
