Flux Core welding????????

admin

what is wrong with flux core welding.  It seems as though flux core welding is not considered "real welding" or is an inferior weld.  Can someone explain?????

Reply:Thats not it. Flux core is used everyday in structural and other heavy welding applications. Its a very legitimate process referred to in a lot of codes and text books.However, joe shmoe (no relation to the member here with a similar screen name) that purchases an HF 151 (or any number of other 110 only machines ie lincoln weldpak 100) with a 2 lb spool of flux core and asks the most basic of welding questions with intentions of welding together his race car frame (from scratch no less) is typically not considered a "real welder". No offense to these types of guys, and we are happy to answer their questions, but these types of welding machines will not get you very far in terms of welding skill progression. For some hobbyists, that is all the machine they will want or need.Hope this answers your question...JasonLast edited by BCRD; 11-18-2010 at 11:12 AM.XMT 350 MPA Dynasty 280DXSuitcase 8RC / OptimaSpoolmatic 30AThermco Ar / C02 mixerAssorted O/A gear
Reply:Hello Phil S, I would just add a bit more to the others who have responded. When you say "flux core" there are a number of wires that could be included under that broad term. There are flux core/gas shielded wires, often referred to as "dual shield", a large number of products and structures are welded with this process/wire combination everyday. There are also flux core/self-shielded wires, this is generally where a lot of the negatives might come from. A lot of heavy structural field welding is performed everyday with this wire/process combination, but the make-up of some of these wires has a lot to do with their successful use. Some of these wires are referred to as "seismic" qualified. Essentially, this means that they are useable in situations where structures are subjected to the rigors and stresses that might occur in an earthquake, many are also temperature qualified, meaning that they are not prone to failure when subjected to low temperature service. There are another family of the flux core/self shielded wires that are manufactured for use in the smaller home type machines, these wires are generally not qualified to the standards mentioned above for industrial type service and don't have the benefits of the chemistries of those either. Flux core wires, both shielded and self shielded have evolved greatly in the last 30 years, yet each one of them has a specific use that they are designed for and will generally work very well if they are utilized for their purpose. A bit more for you to consider. Best regards, Allanaevald

Reply:I don't know who considers fluxcore not ''Real'' welding. As said its used everyday in shops/structural places. Where i work (well did before i got laid off) all we used was dualshield. Much faster and much stronger then using standard mig. I think people get the fluxcore that comes with the 110v migs mixed up with fluxcore/dualshield wire used every day in shops or on job sites.Ya gotta spend money to make money!

Reply:Originally Posted by Fat BastardI would like further explanation of the question, Who is considering it not real welding, or inferior? I think you might have your question answered I am more interested in where and how you came to ask the question.Just curious.
Reply:Every welding process has pros and cons.
Reply:Currently on a job, where we are making moment welds for structural iron. We are running Lincoln 232 5/64 fluxcore. I'd like to think we're real welders. (:
Reply:Originally Posted by Phil S.I've had a Hobart 125 Handler (110v) for about 8 years and welded everything from A to Z with it.  But all I do is Home Owner stuff and tool repairs.  I obviously don't feel it's inferior but everything I see on here has a tank attached to it, so I'm just assuming that real welders considered  Flux Core to be amaturistic.Thanks for all you guy's input.  Now I don't feel Inferior any more.

Reply:NASSCO is one of the largest ship builders in America, with many US Navy contracts.   Just about every ship they build now days is welded with fluxcore wire and submerged arc welding.  Aside from the post-weld spatter clean up, I prefer fluxcore to short-arc mig for most things and use self-shield fluxcore more than any other process for on-site/outdoor jobs.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op

Reply:Originally Posted by SandyHandles mild rust and garbage pretty well with some differences. Of course one guys idea of mild rust is quite different than anothers. I see some guys stabbing away at a re-strike, using the rod like a chipping hammer, just keep stabbing and dragging all over the place till you get an arc going. You won't pull that off with flux core. It'll stub and/or pop back to the tip on dirty starts. It's not stiff enough to hammer at the metal like some do with a stick.  It's best to have a good solid work lead connection and a clean spot to start. Once an arc is started about the only thing it won't burn through is embedded cement film.
