MIG vs TIG vs Stick – Comparing the Different Types of Welding

There are a number of different types of welding. The most popular are MIG, TIG and Stick welding. Each one of these processes has their own benefits and limitations, you just need to find out which one is best suited for the job in hand. Generally speaking, TIG is more suitable for clean, intrictate welds where appearance is paramount ahead of efficiency. MIG is a much easier process but the results aren’t quite to the same standard as TIG.

There’s no “best process” in welding, you have to choose what’s right for you. The chart below outlines the main advantages and disadvantages of the different types of welding.

Process Stick MIG Flux Cored TIG
Metal Type Steel, Stainless Steel, Stainless, Aluminium Steel, Stainless All
Metal Thickness 1/8″ and above 24 Gauge and above 1/8″ and above 22 Gauge and above
Skill Level Medium Low Low High
Welding Speed Slow Fast Fast Slowest
Weld Quality Low Medium Low High
Operating Cost High Low Lowest High
Purchase Cost Low Medium Medium High

MIG Welding

MIG Welding is the easiest welding process for beginners to learn. To MIG weld you will use a MIG gun which will feed a wire electrode out of the welding machine when you press the trigger.


When using a gas cylinder for MIG welding, you use gas to protect the arc from the atmosphere to stop it becoming contaminated. the gas flows through the MIG gun and surrounds the wire electrode.

Pros of MIG Welding:

  • Easy to learn
  • Wire is cheaper than flux-cored.
  • Good quality welds with little spatter
  • Reduced clean up time

Cons of MIG Welding:

  • More complicated setup thatn FCAW
  • Not as good quality as TIG welds.
  • Steel needs to be clean
Gasless MIG (FCAW – Flux Core Arc Welding)

You can also use your MIG welder for flux core welding. In this process, you won’t use gas, but instead use flux cored wire which contains a core that will protect the weld pool from contamination.

Pros of Flux Core Welding:

  • Easy to learn
  • Deep penetration
  • Easy to setup
  • More portable without gas

Cons of Flux Core Welding:

  • Wire is more expensive
  • Thicker wire makes is less suitable for very thin metal
  • Causes spatter that needs to be cleaned

TIG Welding (GTAW Welding)

TIG welding is a more complicated process than MIG welding which takes practice to get right and is more time consuming. The plus side, however, is that it produces even higher quality welds.

In TIG welding you use a torch with a non-consumable tungsten electrode while slowly feeding a filler rod into the weld pool to fuse the metals together. This can be tricky as it requires you to use both hands and a foot pedal to feed the wire, but it produces really precise welds.

Pros of TIG Welding:

  • Higher quality welds than MIG
  • Reduced clean up time
  • Good for precise welds that require attention to detail

Cons of TIG Welding:

  • Harder skill to master
  • More time consuming than MIG

Stick (Arc) Welding

Stick welding or SMAW (Shielded Metal Arc Welding) is one of the more old-school and inexpensive types of welding. It’s used mainly to weld thick cast iron and steel.

In stick welding, a consumable, flux coated rod/electrode is used and an electric arc is formed between the electrode and the workpiece metals. The flux coating that surrounds the electrode then disintegrates and protects the weld pool from contamination.

It’s fairly simple to learn but can require a bit more skill than MIG welding because the rod burns down so you need to make sure you’re keeping the arc at the right distance from the workpiece.

Pros of Stick Welding

  • Can be used outdoors in windy conditions
  • Portable – No shielding gas or wire feeder is needed
  • Produces strong welds, including on rusty surfaces and steel does not need to be clean.

Cons of Stick Welding

  • Produces slag and spatter
  • Lower quality weld
  • Inefficient as increased cleanup time and changing electrodes reduces productivity.
