Difference between Mig and Tig Welding

What’s the difference between Mig and Tig Welding?

The major difference between Mig and Tig welding is that one process uses a continuously feeding wire (MIG) and the other you use long welding rods and slowly feed them into the weld puddle (TIG). MIG and TIG welding both use an electric arc to make the weld.

MIG welding is a very simple and easy process to learn compared to learning how to TIG weld. The technical names for these are metal inert gas (MIG), and tungsten inert gas (TIG).

A MIG welder works by using a continuously feeding spool of welding wire that burns, melts and fuses both the base and parent metals together. You can weld a variety of materials such as mild steel, stainless steel and aluminum.

A range of material thicknesses can be welded from thin gauge sheet metal right up to heavier structural plates.

TIG welding on the other hand is more commonly used for your thinner gauge materials. Items that are made with this process are things like kitchen sinks and tool boxes. The biggest benefit is that you can get your power down really low and not blow through the metal.

Pipe welding and other heavier tasks can also be performed, you just need to have a unit that is capable of putting out the amount of power that you need.

The main difference between MIG and TIG welding is that one method uses a continuously feeding electrode and is a very fast way of putting down welds. The other way is a much more fine and delicate welding technique.

The most versatile machine is the TIG welder as you can weld many different types of metals. The downside is that it is very slow. For anybody wanting to do some welding at home your better choice of machine to buy would have to be the wire feeding MIG welder.

  1. Tig welding skills is harder than the Mig.

  2. Brief and to the point. Perfect

  3. Thankyou very much for a clear view on mig & tig. I have asked plenty people for an opinion and normaly get answers like ” both are good but it is your choice”

  4. great article. really think author is a credible source to learn. the biggest difference is the use of non-consumable electrode in TIG while the use of consistent consumable electrode which is wire, in case of MIG welding process. Thanks alot

  5. This article is fantastic! Each question i had in mind got answer right here and then haha…Many thanks author, you have no idea just how greatful i am for that, really.

  6. Thanks.Really the way explained about TIG & MIG welding are great,points are very clear and crisp.

  7. This answered a few questions I had, but I’m still curious about 1. Does TIG welding leave behind a slack like mig or stick welding?

  8. is consumable for both TIG and MIG are same?

  9. really good article, I have researched several times on differences between MIG, TIG and flux and the above information provides true understandable insights not described by others; thanks, I enjoyed this!

  10. You made this so clear and informative. Thank You

  11. great article. I’ve read a lot about the TIG but never read about the MIG. thanks for your very informative post.

  12. Why “Inert Gas” ?

  13. Nice blog! I like your blog and the knowledge you have shared about learning the difference between Mig and Dig welding. Thanks for sharing…

  14. I am planning on building a wood gasifier. It sounds to me like TIG welding would work better? Opinion?

  15. I have used both mig & tig and I have to say that the wire feed is great for steel the hardest thing to learn was remembering what gas and type of wire for different types of meatal. Then again for thin metal took quite some time to master. Back when I first learned how there was also the option of brazing (still applys) many different types of metal, and a coat hanger could be used on mild steel and sheet metal,That old trick still works but the composition of the hanger has drastically changed and will take a lot more to work. This article was a great read for a layman to understand.

  16. This was very helpful, I am just about to buy a
    welder for amateur use and did know which to buy.
    Now I know, Shall buy a mig. Thanks very much. Kind regards David Long

  17. Thanks for the simple explanation. I agree with John. The answers, from people I have asked, are just like John says.

  18. If current increased in tig what will happen ?

  19. It’s all about what you are trying to achieve. If you need to lay down a nice looking bead or can’t grind on it tig is the way to go. Plus with the tig you can weld any metal that can be welded. The downside is it’s slow and take a while to learn. Mig on the other hand anyone can do it and with some practice you can lay out some nice beads. Tig also won’t warp thin sheet metal as bad.

  20. Thanks very much I thought tig used gas

  21. Great work! You’ve clearly explained the difference between TIG and MIG welding in a way that even beginners will understand. Never thought that TIG welding is a bit complicated and needs a lot of patience. Maybe it is the reason why a lot of people I know who welds chooses MIG over TIG.

  22. Hi, I do not understand adeel’s comment of non-consumable electrode for tig, I thought the electrode was used while you weld?

    Thank you

  23. I too have asked which one is better and the difference. I was told it’s your choice because both do the job.
