what is the difference between mig and arc welding
Today we discuss difference what is the difference between mig and arc welding. Both Mig and Arc Welding are the most common types of welding. They are both done using a torch, which is a device that delivers an electric arc between two electrodes. However, there are many differences between the two types of welding.
What is Mig Welding?
Mig welding (or metal inert gas welding) is a type of welding that uses an electric arc to make the weld.
The main difference between mig and arc welding is that with MIG welding, you have a filler wire feeder that feeds the electrode wire for you. The shielding gas is also used as a means to protect the molten metal from oxygen as it cools. When it comes to shielding gas, there are three different types: carbon dioxide, argon, or helium.
What is Arc Welding?
Arc welding is often used for things like making buildings, ships, and other structures. This type of welding uses a high-current electric arc that passes between two sticks or electrodes to melt metal.
This method of welding is different from MIG welding because it operates through an electric current rather than the heat generated by the torch. Arc welding gets its name from the electrical arc created when the electrode and workpiece are in contact with each other.
The arc will produce a lot of heat which melts and joins (welds) together metals that are then cooled to form a strong joint.
Arc welding is also used in many other industries such as construction, oil and gas, mining, aerospace engineering, and telecommunications. It can be done on everything from steel pipes to aluminum castings.
The Process of Mig and Arc Welding:
Mig welding and arc welding both create a variety of welds. The only difference in the process is in the shield gas used during the process. Mig welders use a gas made from argon and carbon dioxide, which is less dense than oxygen-based shielding gases.
Arc welding, on the other hand, uses an electric current to produce heat that melts metals together. This type of weld requires a shielding gas, such as argon or helium, to protect people from exposure to harmful ultraviolet light.
The need for a shielding gas is why we distinguish between mig and arc welding: Arc welding does not use an inert gas as MIG welding does.
How are the two types of welding different?
Mig welding is a process of welding that uses a wire to create a pool of molten metal on the material being welded. One electrode is held down while the other electrode is raised up and down along the length of the wire to make a tight arc. This creates a pool of molten metal which is then used to weld the materials together.
Arc welding, also known as stick welding, uses an electric arc to create heat between two pieces of metal. The electric current runs from one rod to another, heating them up. These two pieces are then fused together by hitting them with a third piece or clamping them together while they cool off.
When do you use each type of welding?
Arc welding is usually used in the construction of large structures like bridges and skyscrapers, while MIG welding is most often used in the manufacturing of smaller metal objects, like parts for cars.
Arc welding is often done with a machine called an inverter which can move at high speeds and generate even heat across a wider surface area. This means arc welders can work on larger pieces of metal more quickly than MIG welders.
Conclusion :
You have very different needs when it comes to the type of welding you are doing. Mig welding is best for use on steel, stainless steel, aluminum, bronze, copper, nickel, and other ferrous metals. Arc welding is best for use on non-ferrous metals, cast iron, pipework, aluminum, brass, bronze, nickel silicon bronze.
