I think a good thing for anyone who hasn't welded or not very much, is to look into a night class at a community collage. Just the basic class should go over Oxy/Acetylene (and Brazing), Arc, Mig, and maybe Tig
and you can ask the instructor questions and you learn some basic metallurgical properties, all in all if you want to spend the money its worth it.

just my $0.02

I actually did braze a few things many years ago..Came out OK.
If you look around this forum there are post about brazing that are somewhat unflattering. Some say the repared areas become
raised and or bumpy. Something like that. Welcome to Hotrodders Sehlah.

Thanks for the reply. I enjoy responses from hackers(like me) as well as pros. Sometimes a beginner can tell you how he got around a particular situation with out the proper tools etc..in other words how he improvised to get the job done. Ya I have a sneaky feeling that if I continue to do body work..A TIG will likely be in my arsenal someday. Your comments about removing brazing flux may explain some of the bad rap that brazing has. Possibbly it's the corrosive action of the flux that later raises the filler. Welcome Cassidy.

Unstable..

I also tried the die grinder to grind weld. Does work well plus it gives you fine control. My compressor runs out of air too quickly for the die grinder so I took the 3" abrasive wheel off and put it on my disk sander sandwiched between two washers. Worked like a charm. I did get a little too agressive and now I have some holes to close up on sheet metal that has been ground thin. I'm hoping the Harris "20 guage" helps with that.

You know I looked for a course here in CT and couldn't find one. YA know what I'd like even better? A chance to be a goffer for a talented bodyman. Nothin beats watch'n a pro. That would be a great education.

Thanks and ave fun all. Afterall, it is hump day!

Slick,

I know it's been said time and time again...if you haven't already, definitely check out www.metalmeet.com

There are pro metal shapers all across the country who are usually more than willing to let someone work in their shop on the weekend.

I usually drive about an hour and a half each way to go up to Wrays shop on the weekends. Being around someone who knows so much definitely helps. I wouldn't have believed the entire thing about Oxygen/Acetylene if he had not showed me. Nearly everyone on this board and everyone I've come into contact with said "O/A will just warp your panels...use a mig"

Great lead Unstable thank you. Somehow no matter how many times it's been mentioned it did get past me. So thanks for mentioning it again.

You'll find me hiding on metalmeet as well.

Another good BB where you can learn a lot about welding is at Hobart's;
www.hobartwelders.com and the guys are very very helpful and clued up there. Plus it's a very small community so you'll get good advice very quickly.

It really is best if you can attend a class or get a pro to show you the ropes even if it's only for an hour or so.

I'm learning the hard way; buy a few books, troll the net, ask a few questions and then jump in, do it, evaluate and try to do better the next time around.

Interesting tidbit re brazing; here in South Africa lots of panelshops still braze raher than weld panels. It's only the few "upmarket" ones that MIG and even less that TIG. I asked the pro's and every single last one insisted that the only way is to braze.

But do'nt shun brazing - the hand coordination skills you use with brazing will help a lot with OA and TIG welding. Also sometimes brazing is the only way to "weld" diff types of metal together.

Remember each process has it's pros and cons - pretty soon you'll be able to pick the most suitable one for the job. Eg. TIG's only really suitable if the metal is so clean that you can eat off it.
