I would recommend paying someone to do your welding for you, at least this go around. Some people pick up on welding very quickly and some people that claim to weld shouldn't be allowed.

However I would suggest you learn how to weld, it is an indispensable skill IMHO. The better you get at it the more uses you will find for it. I don't claim to be a welder but I can get two pieces of metal to stay together...we call it farm welding

I own both Miller and Lincoln welders and both are good machines.

I would get the use of a welding machine, that will do 150 amps or so with SMAW, get some pieces of 3/8 inch or 1/4 inch angle iron, practice doing some complete penetration welds, vertical up with no stress riser configurations. Since you're in the Dakotas, use a 7018 rod with Charpy Impact of minus 40 charactistics. When you're confident with your welds, then hire the local vocational schol teach to watch your welds on your frame. Don't know those words? Look them up before you hire some guy with a "Certified Welder" mispelled sign on the side of his pickup truck. You'll be happy you did and comfortable with your frame.

Welding is not inherently difficult but it does take knowledge, practice, a steady hand, and the correct equipment. Being able to diagnose setup problems, select consumables appropriate for the process and weld position, and understanding joint geometries is critical to your success.

The standard reference for welding basics is Lincoln's Welding Handbook. I would recommend it to anyone involved, or getting into welding.

https://ssl.lincolnelectric.com/linc...asp?prodnum=PH

There are numerous welding processes of varying complexity and cost but common ones are Shielded Metal Arc Welding (SMAW, aka Stick), Gas Metal Arc Welding GMAW, aka MIG), and Flux Cored Arc Welding (FCAW). You can buy hobby rigs at Home Depot and such that will perform any of these but they are limited in capacity. For the average Do-it-yourselfer a 200 to 250 amp unit such as a Miller Millermatic, Lincoln Power MIG, or ESAB MigMaster offers tremendous flexibility but they're not cheap.

We have SMAW, GMAW, and FCAW processes in our shop but most of my work is with GMAW or FCAW for materials measuring 5/16" thick or less. For applications such as an Airstream frame repair my machine/process of choice would be a Millermatic 252 running an E71T-X FCAW wire, or an ER70S-X GMAW wire.


I urge anyone to spend a fair amount of time practicing your skills before attempting any project welding. I would also add that most Vocational Welding Programs in this part of the country are more than capable and willing to do work of this type for the benefit of their students. Usually the cost is no more than the donation of materials to do the project.
Good Luck,

Kevin

I did call our local welding instructor and he has offered to come and take a look at it for us. Problem right now is we don't have the frame completely off the shell. He wants it completely off and then he could give us advice. He is a really nice guy and I trust his opinion. I don't want to take advantage of him though. I am sure there are plenty of people wanting advice.

We still haven't figured out what is the best way to get the frame off without damaging the shell. We also have to pull the water tanks off-someone put a two by four across the back tank and it is hanging on there by a thread at this point. Amazing we could haul this thing back to ND.

We did buy a "How to Weld" book yesterday but are still thinking for this first time, we need to get someone who isn't on page 14 of the welding book. Thanks for all of your help!

Wink Another month closer to the start of the beginning of the initial phases

My better half would have finished his welding class tonight if it weren't for the 10 inches of snow that blew in yesterday. I am guessing he will get another make up class and then he will be ready to start thinking about the beginning of his initial welding phase on the frame. He said at lunch that he was thinking of having his welding instructor weld up the new frame. He said it might be too big of a project for a new beginner and I replied "Whatever you think. Let's just get to the point we can go camping."

Big plans for Saturday to head over the the local welding shop to look at welders and determine possibilities. Ah, the height of adventure and excitement....it is if you have Airstream dreams and camping obsessions. On a crazier note, I did make up welding doo rags for all occasions...you name it, I made it. Route 66, travel, football, cooking, hunting, etc. and etc. Husband said "Stop already." I guess I don't show him the other 14 I made....

I think I am going cabin crazy at this point. Time to get outside and to work on the Albatross.
