What is MIG welding?

Fabrication and welding techniques are a big part of our services here at Fab-Tech Telford and we are often called upon to assemble different machined parts for our customers.

During this fabrication process, we use two different welding techniques called TIG (tungsten inert gas) and MIG (metal inert gas) – in this article we look at the MIG (metal insert gas) side of the process.

Understanding Metal Insert Gas welding

So, what is Metal Inert Gas (MIG) welding? This is a process that creates joints by feeding the electrode into molten metal, thus creating an arc between them. The two bases are melted together with this action; meanwhile, gas shielding protects your weld pool from airborne contaminants like dirt or rust particles entering through ventilation systems.

MIG welding is a great way to weld metal with the help of electricity. A wire electrode consists largely in its composition, which can be either cored or solid depending on what you’re looking for as far as quality goes – it all depends on how much control over the melting and cool down time your welder offers.

When the trigger of a MIG welding machine is pulled, an arc forms between this wire electrode and workpiece. The heat from that fusion melts both surfaces while also acting as filler metal for any cracks or gaps in between them – hence why some people call it “wire-welding.”

Shielded gases are essential when welding with MIG because they allow you to protect your workpiece or filler material from reacting in any unwanted ways.

The shield can be supplied through an annular (ring) nozzle that surrounds each joint, which means there’s no need for different types of shields depending upon what kind of metal we will be working with; this just makes things easier.

Our services

Experienced & professional welders

We ensure that all our experienced and professional welders receive continuous training which allows them to maintain their high levels of skills which can be used in a wide variety of different fabrication projects.

Not only do we invest in onsite training but also in high-tech equipment and technology which we believe are an essential component of our fabrication services.
