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.

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

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 !

This bloke reminds me of a guy I know. He’s been welding pipe for 51 yrs.I’m thinking of chopping and dropping a beach cruiser.I think i’ll give him a shout.

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!

porosity in the finished weld, which means that air bubbles get trapped inside the weld bead!It also means the metal has more carbon, or the cup size is wrong, the argon mixture or co2 is wrong, rust in the joint, or did you forget to clean the filler wire,(well it dose happen)preheat joint,( it will pull moisture out) The purpose of shielding gas is to keep the air atmosphere away from the weld pool. Without it, the weld pool reacts with the oxygen, nitrogen and hydrogen is that better

The guy is no more than a poster, he make money on his videos, like a Jack of all trades and master of none, Sorry dude! I am a retired Steamfitter, and control tech, UA, (union) I have the nuclear, oil, paper and food industries behind me, I have taught classes on , smaw, tig, mig, s/s 304-to 316ls, dissimilar metals, w/ k and J rings, pulsearc© and the bore scope process, and different type xrays you do a very poor job of explaining the processes of welding and techniques,

There is a big difference between MIG and TIG welding, in both the process, and the skill level required of the weldor. They really are two different processes altogether, and the MIG is the much easier of the two.

There is much to read on the web, including some great information at the Miller and Lincoln websites. They can give you a pretty great overview of TIG welding. But, as with many skills, it takes hands-on practice as well as study, to be successful.

If your fiance has ever welded with a gas torch, he might already have the skills he needs. Unlike a MIG welder, a TIG does not feed an electrified filler wire for you. You are in control of a separate heat source (the torch) that you must manipulate in order to melt the base metal together, while adding the filler by hand to the molten puddle you're creating. It's the same way a gas torch works, just with electricity, rather than gas, as the heat source.

The tricky part comes in learning how hot to make the puddle, how much heat to apply (with a foot or hand controller), and how to coordinate the filler at the same time. Quite often, TIG welding involves metals like aluminum or stainless, which have their own quirks that need to be considered. It's by no means impossible to learn all of this…and it can be a very valuable skill to have, often paying higher than MIG welding jobs.

If your fiance shows this prospective employer that he is a professional who takes pride in his work, has studied the subject, and is willing to learn, he may get his foot in the door and start down a new path on his welding career. I wish him the best. Study all you can, and if you know a buddy who is good with the Oxy-Acetylene torch, go visit him right away for some practice!

Best of Luck!
