Request: Welding Information FAQ v Experienced welders!!!!

ok gang ... here is the idea. i have started writing a semi-technical FAQ for welding ... basically a informational paper in a technical writing format. I hav experience welding in GMAW GTAW and SMAW but i dont know everything and im not trying to sound like i do, but there are a ton of questions that keep getting answered week after week and i think a FAQ might be helpful to JF and others ....

here is what i need:

opinions on what you want into the FAQ from EVERYONE!!! experienced, novice, and anywhere in between.

from experienced welders i would like you to pic a single topic and just write maybe a paragraph on it ... ie Lead angle or Work angle or rod selection or anything else ... keep the topic narrow dont try to tell us how to stick weld in one paragraph ... im looking for this to be ~5 Pages (12 pt, single spaced in Word) for each process .. no technical manual by any means but something that will get people pointed in the correct direction ...

anything else you want to share!!!


DO NOT TURN THIS INTO A DISCUSSION THREAD!!!! i dont want to sift through 50 pages of garbage for 2 pages of gold ...dont argue about someone else's point in this thread ... im going to ask PBB member 'Bigger Valves' for collaborate on this with me and help me write something worth reading ... together with the AWS manual we will decide what is correct and what is not and what is needed in the FAQ.

for those that would liek to help, thank you. for those that want to turn this into a pissing contest, dont bother!!!

thanks guys ... let me hear your opinions!!! if you would like, you can PM me for an anon. contribution or with any questions / comments if you dont want them posted here.

I would like to see some info on joint prep/requirements. ie, when to bevel, when to not, gaps needed, etc. I am somewhat novice I would say. I think this is a good idea and look forward to seeing it.

Mig settings for metal thickness / when to use forehand v backhand / changes in speed req for vertical up and down / tips on determing your penetration.

I have found a wealth of info in these sites, I do believe there are several faqs already in existance. At any rate you can probably
plagorize a wealth of info from them.

http://www.weldingweb.com/

http://www.millerwelds.com/education...isplay.php?f=2

http://www.mig-welding.co.uk/forum/f...splay.php?f=11

Miller and Lincoln have excellent and very active forums as well. There are great threads in there with pictures etc.

If you plan on culling the bad info by using AWS D1.1, why don't you just take all of your info from D1.1? Do you have access to D1.2, D1.6 and D1.9?

I can answer specific questions for you, but your intro was a little vague, so I'm not sure what you're looking for. Also, don't expect JF to write your term paper for you.

I would include a section on welding "non-steel" stuff. Aluminum, Cast, Stainless by using the processes most hobby people have available to them. Stick, Small Mig, Oxy Acetylene.

Another good section would be how to manage warping of stuff while welding. This can be agravating at best. Test fit, test fit, tack, tack, tack, test fit and weld it up only to find it don't fit anymore. LOL

Possibly a couple blurbs on safety.

Impossible to cover everything. What I advise for you and your Lincoln 175 may not be what I advise for someone vastly experienced with a MM 210. Open root is normally relegated to pipe or heavy plate butt joints.

Quote:
Mig settings for metal thickness / when to use forehand v backhand / changes in speed req for vertical up and down / tips on determing your penetration.
Most MIG settings for a given base thickness are included with whatever machine you buy. Unless your talking IPM, V or A. That information is normally provided by the wire manufacturer, and is only a guideline to get you into the ball park. Fine tuning is up to you, and dependant upon a lot of other variables. That detailed information is based upon wire diameter and type. The manufacturer assumes that you already know what diameter wire to use on a given thickness material.

Push or pull? I'm not touching that with a 10 foot pole. I've been welding since 1992, had extensive OJT, and I've seen what works for ME in the Met Lab. I pull EVERYTHING, except for AL MIG. Then again, I rarely MIG anything thinner than .250, I TIG the thin stuff.

V up V down? Nothing I can write will explain V up. Practice, practice, practice. V down is only good if you're experienced, and you understand some basic weld fundamentals. V down with the MIG process has less penetration than V up, and is much more susceptable to cold lap.

Penetration? There are no tips. There is only one way to clearly see your penetration. Section the joint and etch with acid. Everything else is a guesstimate.

Did you read the original post?

I have no problems. I just made my contribution to what he wanted as far as topics.

I did see the original post.

Did I answer your questions?

Do you dispute my generalized answers?

The problems with your questions is that they are too vast for anyone to sit here and type away for days on end. The information is out there, provided by the AWS. I am not going to re-type something already published, or try to recite the volumes from memory. I doubt anyone will.

I'm giving my opinion on a potential topic. I think it's not a good selection. If others disagree with me, so be it. It's only my opinion.

The HF/MM welder scenario was fictional, a hypothetical situation. If it makes you feel better, tell me what welder you have, your experience level, and I will edit my previous post accordingly.

And no, you really didn't answer any questions - but that's not the point of the thread.

Well then, I'll answer everything right here without typing for the next 10 years.

I wish everyone luck with this discussion.

PS-You never responded to my question; Do you have a Harbor Freight welder, or do I need to change my fictional example?

Last thing I want to do is upset anyone in here. I came here to exchange information on a friendly basis, and to help others with the little that I know about welding.
