Working with metals and sparks is more heroic. With this, you can feel the power to transform some of the hardest things of the planet earth. Welding is something that deals with such things.
What welders do is transform the metals and give them a shape they want to. The whole process runs through heat and melting. The experience is familiar to those who are related to different types of welding jobs and sectors.
Now, there are many different types of welding run through various types of processes. To get the skill of welding, first of all, you should learn the different types of welding procedures. Then with practice more and more you can achieve the skills and experiences.
In this article, we are going to discuss the different types of welding procedures, a short history of welding, and some safety precautions during welding.
What is welding?
The definition of welding comes with many forms. Welding is mainly an ancient art or a fabrication or a process that joins materials like metals. First, each part of those metals offered heat, when they are at the stage of melting or become a bit malleable, they are joined with each other.
Then comes the use of filler metal. The filler metal fulfills the gaps and polishes the joint.
History of welding
The history of welding started a long ago from now. Nearly at the 5th BC while the Bronze Age and the iron ages were running then people from the Middle East and Europe started to join metals. Since then, people are making many kinds of weapons and tools with metal.
A saying goes that the idea of welding revealed by the smiths of that time. They started the way to join metal. And now, going through many types of evolution, this is the stage of welding with gas and electricity.
Different Types of welding
According to our survey, there are four basic types of welding which are common and popular all over the world. They are Shielded metal arc welding (SMAW), Gas tungsten arc welding (GTAW), Flux-cored arc welding (FCAW), and Gas metal arc welding (GMAW). Besides, there are more types of welding which are not so popular but exist. They are submerged arc welding (SAW), Electroslag welding (ESW), Electric resistance welding (ERW), and Oxy-fuel welding.
Let’s learn each type with a short description of them.
Shielded metal arc welding(SMAW)
The type is basically known as the SMAW or shielded metal arc welding. Sometimes people name it manual metal arc welding, whatever it is. This form of welding is famous for its high versatility. And just because of the common facts of this type of welding and materials, pieces of equipment, this SMAW welding is famous all over the world. Those who are totally a newbie to welding they also have known something about it.
It’s a type of stick welding and runs manually. The stick consumes electric current to merge an electric arc with which the metals create a bond with each other. Being the most popular method of welding, the SMAW is used in the larger constructional structure.
Gas tungsten arc welding(GTAW)
The gas tungsten arc welding GTAW is also named as tungsten inert gas TIG welding. This type of welding uses a tungsten electrode which is not consumable to grow weld.
This process of welding is a bit tricky and confusing, also a bit complex. This type is mainly used to join thick parts of steel or metal which are not much ironic. This process of arc welding uses an electrode of tungsten to produce heat and weld.
But the fact is this type of welding takes much time to finish and the pieces of equipment and elements are not easy to get off this method of welding.
Flux-cored arc welding(FCAW)
The short form FCAW goes for Flux-cored arc welding or you can call it only FCA.
This type of welding is also known as the replacement of the SMAW welding. Like that one this method of welding is also used for larger construction structures. The interesting fact about flux-cored arc welding is its speed. It’s faster than the SMAW method and saves much time.
The method works best with an electrode which is consumable and flux and permanent voltage with power supply. However, this method isn’t that much popular like the shielded metal method and costs a bit higher. That’s why people often don’t use it in spite of it saves time.
Gas metal arc welding (GMAW)
GMAW stands for gas metal arc welding. It’s also known as MAG metal active gas or MIG metal inert gas.
This method is a bit common classification of welding all over the industrial welding sectors. Shielding gas is used here with the electrode. Which helps a lot to heat the two metals. With direct current power supply and a constant amount of voltage, gas metal arc welding provides peace of mind. Spray, globular, pulsed-spray, and short-circuiting these are the basic methods of transferring metal provided by the GMAW type.
Minor types of welding
These types are not common all over the world. They’re a bit expensive and rare and requires a huge amount of experience and skill.
Submerged arc welding (SAW)
This is an arc welding process. This method uses an electrode and a fusible flux. The submerged flux blanket protects the arc zone and weld.
Electroslag welding (ESW)
This type of welding is very much productive for thicker materials. The range of thickness is between 12 inches to 1 inch. Electro-Slag welding is available from various types of welding positions. You can do it however you want to.
Electric resistance welding (ERW)
This is an efficient method of welding but has some limitations and doesn’t work well with thin metals.
The oxy-fuel welding is also known as oxyacetylene welding. This method is popular in the U.S. and is a bit rare. This welding type uses oxygen and fuel to cut, weld, and merge metals. Pure oxygen is used here to produce more temperature and horrible flame so that metal melt easily.
Safety during welding
Remaining safe during welding is a major issue. Welding is a bit hazardous. Besides, welding means playing with giant metals, heat, and electricity. Though welding is a kind of dangerous work it’s nothing but fun if you follow the safety precautions properly.
To protect your feet and leg from any type of hot melted metal you can grab the best welding boots and the best welding pants from the market. To make safe your body from vibrations and heat there are many types of aprons or jackets in the market. We also have an article on this topic named best welding shirts. You can also check that one.
To learn more about various types of welding, take a look at this video. the gathered information of this video will help you to understand more clearly.
So, at the very end. Here, in this article we’ve described different types of welding procedure and how they work, a brief history of welding, etc.
You might be thinking of is welding bad for your health? Heck no! Welding is not bad for your health. But it’s a bit dangerous. Though it’s dangerous everything has a solution. Welding is not dangerous if you’re prepared to protect yourself.
If you are willing to learn different types of welding I’m sure, this article will help you a lot. Happy welding. Have fun and stay safe.
