A metal inert gas (MIG) welding is a subtype of gas metal arc welding (GMAW), with the other type being metal active gas (MAG) welding, and is a welding process where a consumable wire electrode and the workpiece metal or metals, have an electric arc formed between them that heats up the workpiece metal or metals causing them to melt and join together. This is a process which has to be done well, by the professionals and once that is done, it will become much easier. So what are you waiting for? Get the work done in the right way and get the desired results, but have the right method and tools are very important for that same and you should keep that in mind at all times.
It is one of the most common welding industrial processes and is easy to learn and use. As a result, MIG welders are welders specifically designed to do well using the MIG welding process. If you want to know about this, then you can read more.
Features of MIG welding
Some basic features of MIG welding include:
Easy to use: compared to other types of welding processes, it is easy to use and proficiency can be attained in a few weeks of practice. This is a very important thing and you do not want a product, which makes things very difficult for you. If that happens, then you will need to take some kind of special training for getting the work done and that is the last thing you want.
Versatile: MIG welding is very versatile as it can be used on different kinds of metals. It can also be used for metals of varying thickness. This is something very important; you do not want people to have a product, which is not doing the job. If you buy a product, be sure, that you get the work done in the right way. You need a product which works well in most of the situations and that is a very important thing.
Heat: a lot of heat is generated by this process and as a result, is not ideal for overhead or a vertical weld as a melt through can occur and is obviously a potentially dangerous result and you can also read more. So this has to be kept in mind, you need to understand before buying want will be the impact of the heat on the product. You do not want to pay money for a product and then regret later, that is the last thing you want on your mind.
Safety: it is relatively safe compared to other forms of welding as the gas shield protects the welding area and it produces fewer spatters. This is a very important thing; you should always give it importance. You do not want any kind of mishap happening due to making use of low-quality product.
High productivity: this process results in high productivity as the wire electrode is constantly fed during the process. If you buy a good product from a brand, this will not be a problem and will give very good results. There are many people who are not keeping this in mind and then getting into trouble.
Types of MIG welding transfer
Welding transfer is process through which the metal transfers from the electrode to the weld pool. The three major types are:
Short circuit transfer: here, electricity moves through the gun and creates a short circuit. The wire melts and drips as a result and forms a small pool that creates the joint between the workpieces. It combines low voltage and carbon dioxide shielding gas or a gas mixture as shielding gas. This is a very important thing, which one needs to keep in mind. There are lots of people who buy products, which are not of good quality and then regret later and that is the last thing you want.
Globular transfer: similar to short circuit transfer in the process, mainly differing in the speed of the dripping. While the dripping of the short circuit transfer is fast, which leads to the pool, the dripping of the globular transfer is much slower, which results in a “glob” at the tip of the wire, hence the name. It combines high voltage and argon shielding gas or gas mixture and for more information on this, you can read more.
Spray transfer: this is when the wire melts into very fine droplets or sprays (hence the name) and drops onto the metals being welded together. It is also as a combination of high voltage and argon shielding gas. This is something which could be dangerous for people who are making use of it. If you want such a thing, to be avoided, you need to have al kinds of safety equipments in place without any problems.
Who uses MIG welders?
Essentially anyone who has training to use MIG welders can do so, be they amateurs professionals. Also as a result of its versatility, it can be used industrially and in a domestic setting. There are many good products, you can go in for and once you do that then there will be no problems. Always people who are well trained should go in for this product and if that happens, the chance of going wrong are much lesser. There are many people who make use of these devices without getting into, the right kind of training and then regret later.
Where can they be purchased?
MIG welders can be purchased in good hardware stores or on online stores. Good MIG welders start from $300 and vary depending on what they can do. You may get different options for different pricing. This is a very important thing, which one has to consider. Quality should be one thing; you should keep in mind at all times.
This has been a short introduction to MIG welding. We hope you enjoyed it and you will have a good time making use of it.
