Tig Welding Help

admin

Hey guys I am trying to weld some aluminum flanges onto some .10 inch thickness pipe but for some reason the weld looks like **** it is very pitted and has small black marks in it also I have noticed that when I stop welding the tungsten is very discolored it turns a dark blue colorwhen now for some spec I am using a Riland Tig200WSE Tig Welder it has all the things I would ever need I am also using 1/16" white tip tungsten 15 cfm of 100% argon and about 100 amp of power any help would be great guys thanks here is a link to my machinehttp://www.rilandusa.com/#Riland_Tig200WSE_Tig_Welder_
Reply:The discoloration of the tungsten and the weld that "looks like ****" may be the same problem.  The thing that would cause both these results is inadequate shielding or contaminated shielding.  It's possible you could have a leak at one of the many connections between the bottle and the torch.  A leak can allow air to enter the shielding gas stream.  That's the first thing I would look at.  Plug the end of the torch, activate the gas solenoid, and bubble test everything, even the flow meter.Maybe the blue tungsten is unrelated to your **** weld, and you simply need a longer postflow time.
Reply:the post flow time that I have now is about 5 s I am also thinking that my cleaning width was not set right I had it at like 10% so it spend much more time on one polarity then the other I am going to look at my regulator and all my gas equipment also
Reply:Could also be too long electrode stickout, wind blowing the gas away, dirty metal or filler, taking the filler out of the gas flow while hot then dipping it in the pool...MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op

Reply:Good tips guys I have check for gas leaks and there where none I am starting to think that where I was welding outside it was very breezy that day and could have easy blow away the argon what about clean width and all the settings
Reply:Yeah.... Tig welding outside is pointless. The shielding gas is very easy to blow away. If you have no choice but to tig outside I would get a gas lense, set up some type of curtains or tent around where you're welding, turn the gas up, and wait for a day without any wind what so ever.
Reply:I was having some trouble with the shielding gas and it turned out to be the fan on the little invertor welder that was blowing the gas away. I had the welder sitting on the workbench at one end and was welding about 6 feet away at the other end of the bench. After finally figuring out that the fan was the problem, I moved the welder down on the floor and things improved right away.
