TIG welding typically produces a higher-quality seam than MIG welding. It is also generally easier to weld thin metal pieces using TIG instead of MIG.

The internal structure of the fuselage is generally (from what I recall), a mixture of welded and riveted structure with the skin riveted onto the structure. It would be far too time consuming to weld the skin onto the structure, not to mention the costs involved if a weld is done incorrectly. Until an effective method of mass-producing aircraft is developed (Eclipse tried it and has so far failed), the tried and true method will continue to be used.

Welds are probably huge by the way he’s slinging the tungsten around.

I beleive its called “Walking the cup” its just a easier way/more steady way of moving the tig torch rather then free handing it and being shaky.

It takes awhile to get use to,

What's your question?

I was working for a company welding aircraft parts. APU assemblies for boeing, lear, and raytheon. I was recieving $18 and hour but would have been able to make more through raises and fringe benefits. i ended up quitting because they cut out all overtime. I need certs for all kinds of AL, S.S., And CrMo. I had to get tube, and plate from .020 to .375 certs before I even started welding on the parts and that took a couple of weeks….

I think a lot of people hear about guys making $40 an hour and think they can jump in on that but what they don't realize is those guys have been doing it for years and have recived annual raises etc.

When you talk about pulse tig it is mostly DC welding. You use the pulse to help reduce the distortion. It is mostly used on all ferrous metals. You do not need or have the pulse feature on AC for aluminum. You would need an AC or AC/DC machine for tig welding aluminum. They are some what costly. When tig welding you need to stay with the better name brand welders. Thermal arc, Hobart, Miller, and Lincoln are all good machines. To weld 1/4" aluminum you need approximately 200 or more amps. So this puts you into a machine that is in the $2000 range. Then you need a bottle of argon gas. If welding for any length of time at those amps you would need a water cooled torch. Not to mention the water cooler, foot pedal and all the other items needed. All these items are costly. I am not trying to discourage you but you need to know it is going to cost you some bucks to invest in all the equipment you will need. Good luck!

and its just a accepeted method of pipe welding and is genrally used because it is consitant and usally creates nice looking welds that r sound
