I have searched and read many posts about warp removal, 1st, clamp down solid & don't do long continuous welds. I get that. Then alot of post answers say you can heat in certain areas to bring it back in line. There's my question. Is there somewhere I can read i.e. books or web sites ect. to learn how to remove the warp with heat ? I am a shade tree welder (scarey ) and don't have anyone to watch/ask about this. Or is this just something that has to be passed down welder to welder or in school ect. Thanks, your help/info is appreciated.Miller 252 Mig w/Spool GunMiller Dynasty 350 TigMiller 225 AC-DC StickMiller Spectrum 875 PlasmaOxy/Acet.
Reply:I have had some luck heating the steel where the warp is and then quenching it on the back side of the warp to shrink it straight (or straighter) away from the bend. I too, am a shade tree welder.I offer three choices: Good, Fast, & Cheap.

Reply:Hello missfire, there is an author/fabricator/welder by the name of John P. Stewart, he has a number of books that discuss the very issue you have a question on. I have met him and also have a couple of his books, they are very concise and easy to read and understand. If you google his name and the "flame straightening" topic I believe you will find much of the information that you are questioning. There are a few basic principles that apply to heat and metals: when something is heated it will expand, after it has cooled it will contract slightly more than it expanded. Different materials have different coeffecients of expansion and will expand and contract at different rates when compared to one another. Internal stresses that have been introduced into materials from their manufacture can sometimes alter the ways that warpage and shrinkage will occur. When there is an internal stress and heat is applied it will sometimes release this stress in a different direction than would expected from a strictly expand/shrink definition, get ahold of some of the information that Stewart and others have out there, it will explain much of this in a much more indepth and detailed manner. Good luck and best regards, Allanaevald

Reply:I'M not sure if this applies to what you are doing but sometimes it's best to bend before welding..http://weldingweb.com/vbb/showthread.php...t=Bend+WeldingIt works!...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:I appreciate the info, I looked up the word "warp" not "Flame Straightning", garbage in garbage out as they say. I figured you had to heat then quench but how much heat and how much quench and where is the key i'm guessing. Thanks again I'll look that up...Miller 252 Mig w/Spool GunMiller Dynasty 350 TigMiller 225 AC-DC StickMiller Spectrum 875 PlasmaOxy/Acet.
