Mig and stick on the same weld
Tue, 31 Aug 2021 09:52:30 GMT
Im going to be building some steel canopies made from WT5x11 material. It needs to be done fairly quick, so I was thinking of getting my helper to run the first pass with a 6010/6011 to fill in any bad fit ups while I keep cutting and fitting ahead of him, and then cap it with my 12vs running core shield or dual shield. I was hoping to get everything up and run a first pass on in one day, then cap everything on the 2nd day. Ive built 2 different runs like this before, but only running stick. Would using the 2 different processes cause any issues?
Reply:the two different procceses wont cause any issues, but if you're running duel shield I'm at a loss as to why you'd run any stick at all, most duel shield wires are faster, just as good at filling gaps and perform really well on reasonably dirty steel, cant weld over heavy rust/paint ect, but mill scale, un dressed oxy cut's ect are no problem, why not just run the duel shield all the way?
Reply:It won't cause any issues as long as you get the slag off every time you weld. I've done different processes before with no problem. And alot of times people will Tig weld a root and 7018 the rest. I'm not really sure what the advantage is of that but It can be done with no problem.

Reply:I was wanting to use the dual shield on the entire project but I was trying to keep one welder ahead of the other. I might just go ahead and buy another feeder. Im really enjoying running the 12vs. Wish I would have bought one years ago.
Reply:Originally Posted by ttoksThe advantage of a TIG root with 7018 over it (or solid wire MIG, or duel shield MIG or any number of other processes) is that it's ALOT easier, and not much slower (and with a skilled welder actually faster) to get a consistent X ray quality root with good mechanical properties with TIG then it is with stick, and while it is easy to get a consistent root 6010, 6010 welds also contain a lot of hydrogen, which makes them far more brittle especially at low temps, hence the "good mechanical properties" part, then you switch the 7018 as it's deposition rate is much higher then TIG, or if your extra baller then go duel shield as its at least twice as fast again with almost no downside except needing gas and being sensitive to wind.
Reply:What? Any gaps? What gaps?
Reply:For me, it's easier to run a keyhole with stick and cap with tig. I've done it both ways and it works both ways fine, but my own personal preferences and abilities with each make that my preferred combo. May apply to others as well because my lack of ability to run a cap flat without overdepositing with stick is the issue. I can control the tig cap much easier as far as depositing metal and keep it flatter. I actually do fine with tig root, but who doesn't love a good keyhole burning in and melting.....1957 Lincoln Idealarc 300 AC/DC2020 ESAB ES 180i MiniArcLincoln Idealarc SP200 Lincoln 3350 PAPR CK CK17FV CK CK9FV
