is there someone who can try this?(argon is needed)take an electrode like 6013, 7018 or any other you haveremove coating from the stick try to weld in argon atmosphere and report if it works thanks

Reply:I haven't argon to try
Reply:I would expect that a cellulosic rod would weld very much like it does normally, but 7018 would act much more like 6010.7018 has iron powder in its coating, which helps build up the bead, AND the slag, actually insulates the weld, allowing for slower cooling.  Cellulosics freeze so quickly, because there is no slag protection.Actually, would it be like a kind of GMAW, with really big wire?  Hummm . . .In any case, this isn't really a "useful" technique.In an argon environment, you could just grip a tungsten in your stinger, and TIG with that too.
Reply:Yes it works, I have done this test. Why would it not?
Reply:do you have a camera?could you post a photo?no slag? and porosity?what about difficulty?Last edited by bennett; 04-27-2009 at 03:36 PM.
Reply:Sure I do. Yes I can. First you must answer why, why you want to see, why you want this information? How will this information be used?
Reply:I will use this information for private use onlyIf it will be as I think (welding without slag and without porosity), I will buy argon bottleI hate to use remove welding slag (too much noise for my neighbors)Last edited by bennett; 04-27-2009 at 03:49 PM.

Reply:The only big difference between this experiment and a MIG using pure Argon and steel wire, is the different power supply--CC vs CV. The small details-how to keep the argon just at the tip, proper wetting of the edges, etc. are what will cause the problems with this experimental method.
Reply:Just run solid wire and gas in a voltage sensing wire feeder from a constant current power source, you'll accomplish the same thing and won't have to spend time stripping the flux off a good rod.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:Why remove coating from the stickJust weld with stick in an argon inert atmoshpereOne step will be saved in the procedureWho ever performs this procedure for Bennett please modify accordinglyReport back here with high quality color photographyChop-Chop, daylights burning
Reply:Not sure how you would get gas coverage over that distance BennettBrettA good guess is better than a bad measurement
Reply:If you're stick welding (flux on the rod), there is no point in blowing argon on the weld.  The flux on the rod makes it's own shielding gas as it burns off.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
