Therefore, In this article, I will be explaining all the Classifications of Welding Process in detail with the help of a tree diagram. By burning of gases, if the heat required for melting of plates is obtained called as Gas welding operation. By using electric arc, if the heat required for melting of plates is obtained called as Arc Welding Operation.

Whether it be electric arc or gas welding, each method has its own advantages and disadvantages. Here we will discuss some of the most common welding techniques used in the industry and where they are used.
Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. Welding is usually used on metals and thermoplastics but can also be used on wood. Some materials require the use of specific processes and techniques.

A small amount of pure argon gas flow is allowed through the inner orifice surrounding the tungsten electrode to form the plasma gas. The plasma starts between the tungsten electrode and the orifice by a low current pilot arc. Plasma Arc Welding is the advanced version of TIG welding in which high-velocity and coherent plasma are generated which is basically hot ionized gases. The actual welding process uses plasma gas, and the shielding gas acts as a flux, protecting the weld from the outside atmosphere. It can be used to weld any metal that can be welded using gas tungsten arc welding, which includes almost all commercially used alloys and metals. Plasma arc welding is considered to be an improvement upon the GTAW process because the arc is more focused. The present work mainly focuses on modeling the plasma arc column.
Metals are among the most durable materials on the face of the planet. As such, it has taken noteworthy developments in engineering to mold and shape metal into the machine parts and fixtures you see and use daily. One of the steps employed in metal construction is welding, a process in which a worker melts one piece of metal with concentrated heat on a select spot and then bonds it with a corresponding metal piece. Over time, inventors have developed various methods to weld two or more pieces of metal together. Each of these methods serves a variety of welding applications. The following article covers these and other welding types and definitions.
Resistance Welding : Working Principle, Types and Applications
In olden days, the process of metal welding can be done by heating the metals and pressed jointly which is known as forge welding method. But at present, the welding technology has been changed by the arrival of electricity. In the 19th century, resistance, gas and arc welding was invented. After this, there are different types of welding technologies have been invented like friction, ultrasonic, plasma, laser , electron beam welding. Although, the applications of welding technology mainly involves in a variety of industries.
The female lead, Jennifer Beals, was a welder by day in a Pittsburgh steel mill and for many people that was their first glimpse of what a welder did for a living. Jen reportedly said afterwards that she studied welding for two months before filming began, but because the director wanted more sparks on camera, she was forced to do a terrible job. Perhaps we can let her off the hook. It is used to join pieces of metal together and is a very skilled trade. So what are the different types of welding and what are they used for in industry? MIG welding is one of the easier types of welding for beginners to learn. MIG welding is actually two different types of welding.
Various Flux Application. Methods. ▫ Pouring granular flux onto welding operation. ▫ Stick electrode coated with flux material that melts during welding to cover.

Welding is a permanent joining process in which two pieces of metal together to form one piece by heating the metals to their melting points. Additional metal also called filler metal is added during the heating process to help bond the two pieces together. A welding machine is used to create the heat and apply the filler metal.
