  • TIG vs. MIG

    I am trying to weld some pieces of Steel tubing (1/2" O.D., 0.040" wall t) togaterh to form a structural memeber. There are several pieces of tubings about 7 to 18 " long and go in several different directions. I plan to weld these with a wleding robot. There are a couple of places on the structure, that a piece about 3" of machined steel will be wleded to the structure. What is the best method (TIG or MIG) to use?

    Any help would be much appreciated.

    Thank you

    I would say TIG, just looking at the Dynasty200 specs, it says DC TIG Thickness as thin as 0.004, unless that was a typo, and meant to actually say 0.040, which is what you want it to do?

        I think you'd have a **** of a time Mig welding it. TIG would be the way to go.

          If you can do it with TIG thats the way to go. Better controlability and do a much better looking weld.
