has anyone ever tryed welding with two rods like tig welding only with a stick welder. i did results i found that you could use lower amps and not burn through as easy, welds still look rubbish but at lest you have more of a chance in my view.
It occurs that the gas shield from a rod takes quite a lot of energy to vapourise and work properly. You use a drag technique and the arc forces the slag away. Introducing another coated (or uncoated) rod brings new problems. Might work with a very thinly coated filler rod.
O/A and TIG are usually the other way round in that you feed filler into the heat source as it travels forwards.
More to the point, arc welding has been around for a long time, about a century, and I suspect that if the idea had any merit it would have been explored and products put on the market. Probably it has been explored and found to be useless.
The closest I've got is breaking the flux off stubs and crap rods and shoving them in to make up for poor fit up. I haven't read about it or been told to do it but it seemed reasonable. I doubt it would pass X-ray tests, but the results looked OK.
I have done similar with a mig was doing some 30 mm fillets making some steel 5ft square aluminium ingots I designed, they had to stand the shock of a full crucible about 1.5 tons of molten ally poured into them , and had to be welded inside and out.I had my old lincoln on 500amps with 1.6mm wire flat out, but was still not enough infill so I bought some 6mm bright steel lengths cleaned off the oil and was using that as a filler rod like tig, obviously I was well into spray so had to position the joints so it was down hand but it worked a treat, so did my lincoln best old mig i ever had 500amps continuous
I ran about 8x15kg reels and 4argons in a 30hr period non stop I was nearly cooked !!!
and I felt something that rhythms with it at the end.
glad iam not the only one whos done this!lol but with myself was with duel shield bridgeing root welds on some so lovely gaps the platters have left on structural steel work.
dont think the inspector would be happy if i done it on a witnessed test or allow it!
just knock the flux off first.
also tig rooted pipe with two1.6 filler rods as there was no 2.4mm to hand.
handy trick to be able to do what needs must.(also try welding useing mirrors for when you cant look direct as the weld zone/pool)
I have used gas welding rods as extra filler when Mig welding, very effective but took some getting to grips with. I was doing this on old Clarke welder when building welds up as a textural thing on some sculpture.
