MIG Welding Machine is also appropriately called GMAW (Gaseous Metal Arc Welding). It is a popular type of welding technique used all over the world. It has several advantages to be known as, fast, versatile, easy to learn, and inexpensive. The term “MIG” stands for Metal Inert Gas.
MIG welding is considered the safest method of welding in the welding industry. This is because it involves the minimal possibility of causing burns on the people working on it. By using this type of machine, you can create a straight or a curved, smooth seam. You may want to use this machine when you want to create a seam that may need to cover some part of your product. If you are not familiar with how this device works, then it is better if you read the following.
Working Principle of MIG Welding Machine
The basic principle of GMAW is based on the theory that the welder will pass through the metal while creating a seam. The seam created will be a closed one so that when the welder starts welding, the metals will fuse. Usually, welders use tungsten inert gas to start welding and carbon dioxide to stop it. Some other types of gases are also used but they do not affect the weld puddle and the resultant weld is smooth and even.
Generally, the welding processes that are related to GMAW include plasma arc welding, standard arc welding, and stick arc welding. When you weld metals using a GMAW machine, the process is not affected by the impurities present in the metals and it produces a perfect weld. In addition to this, it also does not affect any of the properties of the metals and the weld is smooth and even. In comparison to other types of welding, GMAW is a reliable process because it is less prone to generate sub-standard welds.
Tips to follow while Using MIG Welding Machine
Before you decide to start welding, you should determine the location where you will place your MIG welding machine. You can do this by drawing a map or diagram and by setting the machine at a suitable distance from the metal surface you want to weld. When you weld, the electrode of the machine will touch the metal surface. You should be careful when you are starting the process because the welds may not be as strong as you expect them to be. You should therefore use some filler wire at a distance so that the welds look better.
In addition to welding indoors, you can also work with a MIG welding machine while working outdoors. You should be familiar with the working environment where you will be working and ensure that you are comfortable with the working conditions before starting. You can use compressed air to cool the gas at the working site if you have portable MIG welding generators. When you have completed the welding task successfully, you should remove the shielding gas from the area. This should be done to prevent contamination. You can then safely dispose of the waste.
