 When should you choose TIG Welding? What are the best reasons to choose the arc TIG type of welding over other types. What are the minimum and maximum thickness arc TIG type of welding can handle? Any advice on the process?

| I TIG just about everything up to about 1/4". Thicker than that it gets stick welded. I've TIGged everything from 24ga SS to 3/16". There really isn't a minimum or max thickness. I've seen soda cans cut in half and welded back together. |

| One reason that you would use TIG would be the cosmetics. And, you can get high penetration in THIN material. You can weld almost any thickness to material as long as you know how to do it properly. I, personally, have gotten a tac to run on a piece of copper the thickness of a soda-pop can. But this process take some skill and practice to get.

| I tend to use my tig only for aluminum or delicate projects where I need the foot control or on projects where splatter is to objectionable and cleanup is difficult. Mig is so much quicker much of the time.

| I always tig weld bronze, brass, copper, thin aluminum and thin stainless. I often tig weld cast iron with silicon bronze rods. I sometimes tig thin steel if there is no mig available. I tig thick stainless if I need to weld out of position, or if I want to fuseweld only. I prefer to weld thick stainless with a stick. Thick aluminum with a spool on gun or push-pull mig. I tig weld mild steel if looks are critical(bike parts). |

| for Aluminum and Stainless steel, make sure you charge more as the gas and consumables and the initial set up are expensive.

| Junior is right, consumables are higher. TIG is used in industry for stainless ( fittings, pipe, tanks etc ) a fair bit as well as aluminum. TIG works well for carbon too when you need a nice sweet stout little weld someplace that is gonna show up and you want cleanliness as well as strength.

 When you want to make it real pretty  I work in a refinery and all of our Stainless process piping is TIG an well as some carbon steel pipe. Some pipe is 1/2" thick and still Tigged. Stick weld is on its way out at least where i work. Some refinerys have outlawed all stick except for 7018...Bob |
