Looking forward to having a career in welding but feeling overwhelmed by all the welding processes there are?
The process of welding must be difficult without knowing about the different types of welding. Some of the processes are very easy to understand, while some are very difficult that could not be understood by the people easily.
Before going into detail of all the welding processes, let’s have a look at the three most commonly used welding processes.
What are the three main types of Welding?
1. Gas Metal Arc Welding (GMAW/MIG)
This type of welding is also like a metal inert gas MIG. This process uses gas to defend the wire made up of an electrode that provides heat to join two metals. This process of welding requires a common voltage and also direct current power source that is the most common method of the industrial welding process. It has four primary methods that are used by the welders in the welding of metals. These methods of welding process are here, such as metal transfer globular, short-circuiting, spray, and pulsed-spray.
2. Gas Tungsten Arc Gas Welding (GTAW/TIG)
The most common use of the that is the welding of thick sections of stainless steel or non-ferrous metal. This is also an arc-welding process that has tungsten and electrode to create the weld. This process is very much complex and needs more time as compared to other processes of welding. But most of the welder does not prefer this kind of time-consuming process because more methods are present that give such a great response in a very short.
3. Shielded Metal Arc Welding (SMAW)
With the popular process of welding, welders use a manual process of stick welding. In this process, the stick uses an electric current to produce an arc between the stick and metal to be joined. For joining these two things, you must require electric current and also heat that will help you in joining these things. This process is normally used in the construction of steel and fabrics to weld iron and steel. It means that it is normally used in hard constructions such as steel and iron.
So with that out of our way, let’s look at all the other types in detail.
9 Different Sub Types Of Welding Processes/Technique
Here you will get different types of the welding process, and you will get the methods from these. Some of the processes are given below.
1: TIG Welding
TIG welding is also known for the name of Heliaric and gas tungsten arc welding denoted from (GTAW). With this kind of welding, the electrode will not be useable, and it is made up of tungsten. A few types of welding is done by filler metal. In this welding, you will use only two metal that will be welded together. Add a filler metal if you want, but you have to fix it by your hand. In TIG welding, you need a gas tank to provide air for the protection of your welding process. It means that it will give a perfect response in the home and away from elements.
Have a look at some of the most affordable TIG Welders.
2: Flux-Cored Arc Welding (FCAW)
These types of welding are just like MIG welding. However, the MIG works more efficiently as the FCAW welding process. Like MIG, the wire works as an electrode, and the filler metal is fed through your wand.
Here you will feel the difference. For FCAW, a core is present for the wire’s flux and having the protection of gas around the weld. Through this, it will decrease the requirement of gas for external. FCAW is normally used for thicker and heavier metals because it is a high-heat welding method.
3: Stick (Shielded-Metal Arc Welding)
The process of welding starts in the 1930s, and many updates come with the time to make it improve. It is a popular method of welding because it is very easy to learn and to do and requires a low amount of time to operate. However, it does not gives accurate welds because it moistens easily.
You must clean it regularly because it is very important to get the best result. A changeable electrode stick act as filler metal. An arc is a design that joins from the end of the dick to the best metals that helps in melting the electrode into filler metal and to build the weld.
Here is a descriptive video about FCAW Welding. Do watch it!
4: MIG Welding
MIG welding is the type of welding that can easily be performed by welders. MIG means the inert metal gas, and sometimes it is called gas metal arc welding (GMAW). Being in this process, the filler metal can be fed with the help of a wand while the gas is removed around the shield it from the elements of outside. All this means that it is not perfect for outdoor use. You can use it in different welding types of metals of different thicknesses because it is versatile. The filler metal is useable and fed through the spool. Furthermore, it is also working as electrodes.
5: Laser Beam Welding
This type of welding is normally used in melting or thermoplastics. As the name shows that is has a laser to give heat to them and leads to weld. This welding can be used on carbon steels, stainless steels, HASLA steels, titanium, and aluminum. It is easily automated with robotics, and because of this, it can be used in manufacturing, such as in the automotive industry.
As shown in all the necessaries of this welding, you can use it in various requirements. The laser beam welding is the very popular process of welding that is very efficient and like by the welders as it is used for aluminum and other hard materials to join together.
6: Electron-Beam Welding
This type of welding where a high-velocity electron produces heat through kinetic energy and welding two materials together. It bis the very high form of welding that is performed by a machine and generally in a vacuum.
Through that kinetic energy, the welding process works because of joining materials together. You must require heat for this. Different type of welding requires different processes. Every welder needs the best welding process to perform their work accurately. Electron-Beam welding is the best way to use for welding because of the efficiency of this type of welding.
7: Plasma Arc Welding
Plasma arc welding is just like a GTAW, but a small arc is used in this, and it gives more working efficiency to the welding. This process has different torches that have heavy temperatures. Gas is pressurized in the wand to produce plasma. Then the plasma gets ions to make it electrically conductive. Through this, the arc is created and uses to produce very high temperatures to melt the metals of the base.
This can free the arc to perform welding without any filler metal, and it is another property of this process like TIG welding. This type of welding provides deep weld penetration with narrow welds. It helps in creating aesthetically pleasing welds with having a high level of strength and power.
8: Atomic Hydrogen Welding
Atomic hydrogen welding is one of the hottest weldings that needs very high-heat that is also known as arc-atom welding in this welding electrode made of tungsten to protect it and use hydrogen gas also for protection. The hydrogen gas is normally used in the process of welding.
The temperature of this welding reaches high above those of an acetylene torch and also works without having filler metal. But this welding is quite old and not that efficient like the latest version of processes tool. This welding has been replaced by MIG welding in recent times. This is very easy to use and also very best, but after the new processes come, it is down because they are more efficient as compared to this process of welding.
This is the advanced process of welding that is used to join the thick edges of two metals plates vertically. The weld is not applied to the outside of a joint you will found it in between the edges of two plates. You can be fed a copper electrode wire through a useable metal guide that also acts as filler metal. When you provide power to it, the arc will be produced, and a weld is produced at the bottom of the seam, and it will moves slowly, producing the weld in place of the seam as it goes.
This will be an automated process and will be performed by the machine. This process of electro slag acts as a machine, and the welders use it very easily and simply and get the perfect response to use in joining the metal with each other. It is very liked by the users.
Simply put, a wide amperage range means a wide variety of materials that can be welded. Low current in the range of 5A to 100A is generally used for softer metals like Aluminum depending upon its thickness and higher current usually above 100A is used to weld hard metals like steel.
Hopefully, you will get all the points about the process of welding from the above discussions. There are still other types of welding types out there but these were the most commonly used and should give you a good overview about the various kinds.
As we discuss a variety of different process of welding also tells about the main types. Some types require a machine to work or need expensive equipment. While some are performing with its specialties in the home without breaking the bank. If you are looking to get any type of welder, then make sure to read the guide about that, it will help a lot.
