Understanding the Difference Between MIG and TIG Welding

MIG and TIG are two of the most common and versatile processes in the world of welding. In both, we utilize welding wire to create joints that are so strong and rigid but there is a big difference between them in many ways: applications, techniques & there are also different types of wire which are supposed to be used. At Udo. At Welding Alloys Thailand, we have a comprehensive array of welding wire available for MIG and TIG welding for you to determine the appropriate process for your unique use. We will take a look at some of the primary differences between these two common welding techniques.

The Speedster: MIG Welding (GMAW)

  • MIG Welding, or Gas Metal Arc Welding (GMAW), is a process that is performed semi-automatically or automatically using a constantly fed consumable electrode wire with a shielding gas to protect the weld from contamination of the atmosphere.
  • Welding Wire – MIG welding would often employ solid or flux-cored wire. Bare wire Bare wire is the wire that melts in a making the weld. Flux-cored wire has a flux core that generates its shielding gas and contains alloying elements, so it is used in outdoor applications and for thicker materials.
  • Applications: MIG welding is used in a wide array of industries due to its speed, ease of use, and adaptability. It is frequently utilized for automotive fabrication, body work (plates are bent to match the curve of the vehicle), construction, shipbuilding and general jobbing work.


  • TIG By comparison, Stick welding speed is quite much slower
  • Easier to learn and operate.
  • Best for heavier fabrics.
  • Some applications can be automated for high volume requirements.
  • Disadvantages:
  • Produces more spatter than TIG.
  • Not suitable for thin or delicate materials.
  • Greater post-weld clean-up needed

TIG Welding (GTAW): The Stainless Precision Artist

  • Manual TIG welding (Gas tungsten arc welding, GTAW): non-consumable electrode and inert gas (argon or helium) shielding the weld pool. A filler metal (welding wire) is manually added to the weld pool by the welder.
  • Welding Wire: TIG welding uses solid wire more typically than it does filler rods, and those filler rods are only used when needed for specific applications. Conversely the wire is selected depending on the base metal, what will be welded and how it is to become welded
  • Applications: TIG Welding is widely used for precision welds and high-quality welds. It is commonly used for aerospace, automotive and precision manufacturing applications where appearance and weld penetration are priorities.


  • Creates clean spatter-free welds
    • This helps you have more control over the weld pool as well as the heat input.
  • Good for thin and fragile materials.
    • The all position, all spool metal cored wire is suitable for welding stainless steels, aluminum and exotic alloys.
  • Disadvantages:
    • Moving the welder more slowly than MIG.
    • A more skilled, experienced mastery is needed.
    • It is not perfect for high-volume production.

Selecting the Correct Welding Wire for a MIG or TIG

The choice of welding wire depends on the base materials and also the application. With MIG welding, look at the thickness of the material, shielding needs and what weld properties you want (strength, corrosion resistance, etc). For TIG welding, always match the filler metal composition to the base metal, a must for both preventing discontinuities and creating sound welds., your welding companion

At Udo, all our MIG TIG welding wires are of superior quality. You can turn to our team of experts in helping you select the right wire for your application and help determine the proper technique when it comes to welding so that you will get the most out of your work.


These differences also help to determine when to use a MIG welder and when to use a TIG welder – and which type of welding wire is appropriate for each. TIG welding provides exact control for fine components, while quicker MIG welding is far better suited to thicker materials. By implementing the correct process and welding wire, you can guarantee that your welds are as high a quality level and performance standard as technically possible.
