MIG Welding

We understand that there is a lot of information to grasp with welding. At Dynaweld, we are Welding Supplies Experts and this puts us in a good position to help you out with your welding needs – big or small. Andrew Bosco from Dynaweld explains the differences between different welding processes. In this video he explains Mig Welding and its benefits.

MIG welding is a great process, especially if you’re just starting out. MIG refers to Metal Inert Gas welding. It uses electricity to melt and join pieces of metal together. During the welding process, an electric arc forms between a consumable MIG wire electrode and the workpiece metal. This causes them to melt and join. It is much like using a hot glue gun, making it one of the easiest welding processes to pick up.

How is it different to TIG welding?

How is it different to TIG welding?

The major difference between MIG and TIG welding is that one process uses a continuous feeding wire (MIG) and the other uses long welding rods and slowly feeds them into the weld puddle (TIG).

MIG welding can be used with gas, which flows from the welding gun, to shield the arc from contaminants. Or without, in which case, the gas comes from the wire itself.

Argon gas or MIG Gas are commonly used in MIG welding because it does not react during combustion. It helps to keep oxygen and water vapour away from the weld.

The wire is fed through the wire spool by a drive motor. The welder moves the torch along the joint line.

The welding power supply has two settings controlled by dials: Voltage control and Wire Speed control. These have to balance.

There are 2 types of wires for MIG welding.

Wires that require gas and gasless wires that don’t.

Gas or no gas?

Gas or no gas?

Gas welding produces little to no smoke. With the gas wire the welder can easily control technique and the speed of the weld pool. This is excellent for fast jobs. Plus there is no slag to clean off when it cools.

Gasless MIG welding does not require external shielding gas which means that it works well outdoors or when you’re having to move locations. You don’t need an external gas tank or need to set up external windshields. Very convenient!

TIG welding may well be MIG welding’s prettier cousin – producing a more aesthetic weld – but MIG welding has the easier personality.

It is much more simple to learn than TIG and is often the go to welding process because it offers a fast workflow.

Choosing MIG will give you a wide choice of metals and thicknesses. All-position welding capability. A good weld bead with low distortion. A minimum of weld splatter.

MIG welding is well suited to maintenance, small projects and automotive repairs.

You can use mild steel, stainless steel and aluminium.
