Comments on: TIG Welding Requires Professional Welders

Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma.

GTAW is most commonly used to weld thin sections of stainless steel and light metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing procedures such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds. However, GTAW is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques. A related process, plasma arc welding, uses a slightly different welding torch to create a more focused welding arc and as a result is often automated.

Thanks! Glad to make your day a little happier.

Great job giving a clear explanation & bursting the bubble for some of those folks making it sound like you need a 10 year internship to learn the basics. (maybe that’s what they needed though)

ROFL on the kermit comments !! I didn’t read them until after watching the video and only then it occurred to me.

thanks for the video!
Great video

Question for you. I am getting into motorcycles/motorcycle fab work.
For this type of purpose, which type of welding it better to learn/use…MIG or TIG?

Sounds good man,
i am going to be taking some welding courses in the new year…

So i am sure that i will have a whole bunch more questions for you then!

again, thanks for the input

You will weld in accordance to the weld procedures that will be given to you for the specific materials mentioned.

Please read:
What is right for you, MIG or TIG? For certain type of work TIG is required, like welding chrome moly for some racing organizations. Intricate work, like gunsmithing is also well suited to TIG. TIG is used by many auto restorers who prefer a more precise, perfect finish that requires little to no finish work. TIG is most similar to gas welding in technique, so if you've done oxy-fuel welding, TIG should be a natural transition.

TIG stands for Tungsten Inert Gas welding. Also called GTAW (Gas Tungsten Arc Welding) and Heliarc® which was Linde's trade name for the TIG process when it was introduced many years ago. The arc is started with a tungsten electrode shielded by inert gas and filler rod is fed into the weld puddle separately. A slower process than MIG, it produces a more precise weld and can be used at lower amperages for thinner metal and can be used on exotic metals. TIG does require quite a bit more time than MIG to learn. It is similar in technique to gas welding.

MIG is required by law and by insurance companies in many localities for structural repair of automotive frames. MIG is also much easier to learn and faster to weld. For doing other types of welding, like sheet metal, it can be a matter of personal preference. For an auto body repair shop or a novice welder, a MIG is a good, practical all-around welder.

After welding and if application is critical , solution annealing is preferable.

What you have to your advantage is being able to Oxygen- Acetylene weld. You need to be able to use both hands. One to manipulate the TIG Torch and the other hand to feed and dip the filler wire. Good Luck !

Thank you! It is nice to see all the comments on this video. I am feeling a lot more comfortable in my “teacher” role. Please check back often, I update about once a week.

Come out to the website and sign up for the newsletter. It only goes out 4 times a year so it is not to annoying.

If you get the chance please give me a rating also

Well.. if I had to pick one I would say the TIG. It would give you a wide range of welding options from steel to alum. Just be careful of the electronics on the bikes. The high frequency from the arc starting can fry computers. Disconnect the battery before welding and keep the ground clamp as close to the weld as possible.
