cation FABRICATION PROCESSES 1. FORGING- It is a manufacturing process involving the shape of metal using localized compressive forces .forging is often classified according to the temperature at which it is performed: cold, hot or warm forging . forged parts usually require further processing to achieve a finished part.
Forging can produce a piece that is stronger than an equivalent cast or machined part. As the metal is shaped during the forging process ,its internal grains deforms to follow the general shape of the part. As a result ,the grain is continuous through the part, giving rise to a piece with improved strength characteristics .
Some metal may be forged cold, but iron and steel are always hot forged. Hot forging prevents the work hardening that would result from cold forging, which would increase the difficulty of performing secondary machining operations on the piece. 2. Welding Operations :
There are two types of welding being done: * METAL INERT GAS WELDING ( MIG ):
It is a welding process in which an electric arc is formed between a consumable electrode wire electrode and a work piece metal, which heat the work piece metal, causing them to melt,and join. Along with a wire electrode a shielding gas is fed through the welding gun,which shields the process from contaminants in the air. The process can be semi –automatic or automatic. A constant voltage, direct current power source is most commonly used with mig ,but constant current systems ,as well as alternating current ,can be used. Mig is applied to steels because it allowed for lower welding time compared to the other welding processes.
It is most commonly industrial welding process, preferred for its versatility ,speed and the relative ease of adapting the process to robotic automation.
The basic necessary equipment is a welding gun, a wire feed unit, a welding power supply, an electrode wire, and a shielding gas supply . the control

    Forging is a specific manufacturing process which involves metal shaping using localized forces. This process has numerous advantages to the people using it as it produces a form of metal that is way stronger than a metal which has been fortified by a cast or a machine part. With regards to metals like steel and iron that are the most often used materials in the construction industry, this durability and strength is the main factor to their appeal and their functionality.…

    Metal Inert Gas (MIG) welding, also sometimes called Gas Metal Arc Welding (GMAW) is a process that was developed in the 1940s for welding aluminum and other non-ferrous metals. MIG welding is an automatic or semi-automatic process in which a wire connected to a source of direct current acts as an electrode to join two pieces of metal as it is continuously passed through a welding gun. A flow of an inert gas, originally argon, is also passed through the welding gun at the same time as the wire electrode. This inert gas acts as a shield, keeping airborne contaminants away from the weld zone.…

    Assembling (joining of the pieces) is done by welding, binding with adhesives, riveting, threaded fasteners, or even yet more bending in the form of a crimped seam. Structural steel and sheet metal are the usual starting materials for fabrication, along with the welding wire, flux, and fasteners that will join the cut pieces. As with other manufacturing processes, both human labour and automation are commonly used. The product resulting from fabrication may be called a fabrication. Shops that specialize in this type of metal work are called fab shops. The end products of other common types of metalworking, such as machining, metal stamping, forging, and casting, may be similar in shape and function, but those processes are not classified as fabrication.…

    One type of popular welding that you can learn to do is arc welding. Arc welding is highly used because it is cheaper to do than the other types of welding. The arc welder has a device that has an electric current that goes through it. A arc welder can give a weld that looks like an arch. Another highly used type of welding is MIG welding. MIG stands for metal inert gas. MIG welding is a type of welding where the welder uses a gas to shield the weld metal. MIG welding can be used for many different jobs. There is also different types of MIG welding. One more commonly used type of welding is TIG welding. TIG stands for tungsten inert gas. TIG welding is similar to MIG welding. The major difference between the two types of welding is that TIG welding uses a tungsten current form while MIG uses a metal electrode. There is also many different types of TIG welding that you can learn how to do. There are many other types of welding including heliarc, hydrogen arc, plasma arc, water jet cutting, percussion welding, thermite welding, forge welding and magnetics pulse welding.

    Welders actually use many other tools than just a standard TIG, MIG, and stick welder. Welders on a daily basis operate safety equipment and use safe work habits, such as wear safety glasses, inspect their clothing, and wear the proper shade tint while welding. This is very important because welders can get hurt very easily by not wearing the proper safety equipment. They also examine work pieces with straight edges or templates to ensure conformance to specifications. Welders also use hand and power tools to clean welds and work on parts. Welding also involves cutting the material. Welders cut material by suing a plasma cutter or with a torch. The plasma cutter is more efficient, but the torch is much more exciting in my opinion. The main thing a welder performs is welding. Welders will perform many different types of welds. The most common type of welding is SMAW welding, which stands for shielded metal arc welding. Stick welding involves using a shade 9 or 10 level tint. Stick welding is done by turning on the machine and attaching the clamp to another piece of metal. Next the welder has to strike the arc by touching the electrode to metals that needed to be welded. A MIG welder is actually stronger than a stick welder, just from my experience welding and learning from others. MIG welding is commonly referred to as wire welding. This is also called GMAW welding, which stands for gas metal arc welding. This type…

    Welding with a rod is called SMAW (Stick Metal Arc Welding), you will absolutely need to know the type of welding if you are planning to be a pipeliner. SMAW is one of the hardest types of welding to master, and it is the most effective. Most welders start off by learning how to weld with a rod. There are also two more types of welding along with brazing and oxyacetylene cutting. GTAW better known as tig or tungsten arc welding is absolutely the hardest type of welding to learn mostly because you need very steady hands and good hand-eye coordination. GTAW is used to weld very thin metals such as aluminum, copper, etc. GMAW is the easiest type of welding and can be used for mostly anything. Some beginners use this if they cant get SMAW down, this is just an easier route. GMAW isn’t the strongest weld to put on something you want to hold a lot of pressure or something you want to last for a very long…
