Welding is one of the most advanced methods of joining metal components and is used in almost all industries. The process of welding involves combining two pieces of metal or more by applying heat and pressure at specific points.
One of the most common welding processes used worldwide is Gas Metal Arc Welding (GMAW), also known as Metal Inert Gas (MIG). It is a semi-automatic welding method that is primarily used for joining thin metal parts. In this article, we will discuss the GMAW process and different types of welding machines used for GMAW.
According to estimates, around 30% of the total welding production market is comprised of GMAW welding processes. This article will cover various aspects of GMAW welding machines, from the basics to deeper technical specifications.
So, if you are looking to know more about this process and the welding machines used for it, read on!
What Type of Welding Machine Is Used for GMAW?
Gas Metal Arc Welding (GMAW), more commonly known as MIG welding, is a type of arc welding which uses a consumable metal electrode and an inert shielding gas for protection against contamination. The type of welding machine used for this process is called a MIG (Metal Inert Gas) welder.It is an electronic device specifically designed to weld metal together.
The Parts of a GMAW Machine
A typical GMAW machine consists of a continuously spinning wire feeder, an arc generator, and a gas valve.The wire feeder feeds a metal wire into the arc generator, which then welds the metal together. The gas valve delivers an inert gas to the weld site, protecting it from contamination.
What Types of Metal Can Be Welded With GMAW?
MIG welding can be used on many different types of metals, including aluminum, stainless steel, carbon steel, and cast iron. It is often used for welding larger parts and in places where it is impossible to reach with stick welding.
Types of GMAW Machines
There are two main types of GMAW machines on the market today: constant current (CC) machines and constant voltage (CV) machines. Constant current machines produce a steady electric current that can be adjusted to the desired level.Constant voltage machines use a predetermined voltage, allowing the user to adjust the welding amperage.
Factors to Consider When Buying a GMAW Machine
When selecting a GMAW machine, there are several factors to consider. First, you should decide between a CC and CV machine.The type of metal you are welding, the thickness of the metal, and the electrical current your machine will require should all be taken into account. You should also take into account the duty cycle and available amperage of the machine.
