I see alot of hard wire welds on here, but what about dual shield flux core?post some pics, with the type of wire and material you used!I will also take some pics at work tomorrow.

Reply:I know this is an old thread but . . . 3/32" Hobart TR70 run on a turn table. Then some .045 select arc wire.
Reply:Thanks for bringing it back.  I have to ask, WTF is going on with mine?  HELP?   1)  The wire - Esab dual shield ultra 71 .035"2)  Sample run fast on 16ga tubing - 18v, probably 270ipm, C25 gas.3)  1/8" angle to 1/8" plate - 27v, into spray territory?  probably 540 ipm,C25.4)  14ga x2" sq tube to 1/8" plate, ditto settings.5)  Same settings 1/8"  to 1/8".I don't understand the goofy long voids, nor the convexity.  Expected very smooth slightly concave fillets at these settings.  Next post a 6th pic for comparison; its a no-name .045 with similar settings. Attached Images... continued.  This is the other end of the 1/8" angle and 14ga tube welded to 3/16" diamond plate with "Euroweld" .045" (a dollar a pound ebay n.o.s.) with similar settings.  Can anyone enlighten me where the I went wrong with the dual shield?  I tried the esab 71 because I saw Shane's post 13, pics 6, 7&8 in an older thread - very impressive!

Reply:What shielding gas are you using? (flowrate, etc.)  Also, your settings seem cold.  I've never run .035 7100 but I've done a lot of .045!  my flat weld temperatures tend to vary anywhere between 27 and 29 volts.If you squint, you can see the welds!  Mind you, they're not 7100 ultra, but they are done with dualshield wire!"Well what's so special about that?"  They're full pen welds (3" to 1"), ground flush and capped with a 1/4" fillet on both sides, UT inspected.  first sideand the backgouged sideAlso passed my all position CWB FCAW through this company, but I don't have pictures of that!

Reply:Wow MB, that's a pretty serious piece of metal!  I was using C25 with about 15cfh flow rate.  I think the esab literature recommended co2 gas but said C25 was okay too.  Couple other welds looked good, but those goofy cavities kept showing up kinda randomly.  I don't think I had enough seat time to dial it in.
Reply:Fabn4Fun,Your pictures show a wormhole porosity that has broken the surface.  It's generally stated that porosity is due to the absorption of oxygen, nitrogen and hydrogen into the molten weld pool. The gases are then released during weld solidification. As the gases try to rise to the weld surface some gas pores will become trapped in the weld metal, some pores pass into the weld slag, while other pores will combine on the weld surface under the slag producing worm tracks.Dual shield flux core wire seems to be more sensitive to the problem.I've seen it when the shielding gas is set too high.  There are some pics of this here:http://www.weldreality.com/flux%20cored%202.htm  Search for worm tracks in that article and you'll find the MIG flux core discussion.Other causes include:excessively long or short arc lengthwelding current too highinsufficient or moist shielding gastravel speed to fastbase metal covered with oil, grease, moisture etc.wet, unclean or damaged electrodes.
Reply:okay, i'll bite as well, but it's a new process for me so try to play nice   - only been using the process for a few months but managed to pass my 2 and 5G FCAW certs (xray) a month or two ago.  Don't have pics of that but here are a couple of passes I did on some angle while (3G) dialing in my machine at work the other day followed by a couple on nozzels that were done vertical to flat.  I hope these pics post right and try not to be too harsh guys,,, it's the first time I've finally gotten up the nerve to show my work.  The specs are as follows...Kobelco Frontiarc 7-11 .045, 100% CO2.  Hobart machine (forget get the make, ill look tomorrow if anyone cares) running around 28,5v and wirespeed i cant for the life of me remember,,, in and around 240 inches i believe, but again ill check my notes tomorrow.  We also run alot of the same wire in 1/16th too so if anyones interested ill try to grab pics of that or even the big stuff (3/32) we run occasionally.  I'm really more of a stick welder, but I'll run whatever I get paid to   hope someone enjoys.
