7018 up

admin

Ran these beads today and would like some input. Both the top beads are 1/8 inch at 110 amps. The bead under is 3/32 at 90 amps and weave a little inconsistent as I was trying some different things. The bead on the right is just stringer bead with very little manipulation.  The rod angle was 90 to 5 up and the bead came out more crowned then I would of liked so on the left bead I tried angling the rod up about 20 or so to see if I could flatten the bead some.  It didn't do much, made a more inconsistent  bead and it got away from me at the top. When it got away the piece was getting hot after 3 beads and not enough time between for it to cool enough. I did stay in and shortened the arc and angle the rod up trying push it, but it still spilled over.  Anyway just wanting to know what I  may have done to flatten the beads and to keep the last from spilling out at the top, other than waiting for the piece to cool more.  Also is there anything wrong with putting one bead on one side, one on the other and then running one down the middle, rather than over lapping them left to right or right to left? I did it this way to have a clear view of both beads, but was thinking I kind of liked it.Thanks, Phil Attached Images
Reply:Is that 1/4" plate?  Can't tell from the pic,  using thicker steel will help with the overheating problems. I find keeping the rod at a 90 works best for me,  and maybe try increasing your travel speed? http://www.philswelding.com
Reply:Looking good, keep doing what your doing.You'll get it soon  I usually do a little side to side wiggle. Helps tie into the side and the adjoining bead.Just a couple welders, big hammers, grinders, and torches.Work will free you.Men in dirty jeans built this country, while men in clean suits have destroyed it.

Reply:I’ve taught several people how to run 7018 vertical up hill. One thing I’ve noticed, is when they get close to the top, they forget to raise their shoulder. Which makes them loose the rod angle, so the puddle boils out.Don’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400
Reply:Since that's just practice, you could cool it with water.
Reply:Thanks for the replies guys.  Metal the pieces are 2 1/2 angle tacked point to point, there about 3/16 a the edge but have more meat in the middle. Ill try speeding up a bit.  AK thanks for the compliment, thanks has to go to the great abvice ive gotten on here, did use just a bit of wiggle.  Cep, I did have the rod angled up maybe 25 degree for the whole bead on the left maybe more at the top. My thinking was it would push the puddle up, flattening the bead. I guess maybe it put the heat out in front of the puddle. Now what about one bead on one side one on the other and then one up the middle, OK or should I lap them half over each other from one side to the other.  Be putting one up the module tomorrow.  Stay tuned. Thank againLast edited by Phil Snyder; 01-28-2016 at 10:17 PM.

Reply:Looks good to me To your question - I've run like you did with one up the middle, I liked it too.I don't know a definite answer, but I do recall reading some people in another country had written approval for it.Dave J.Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~ Syncro 350Invertec v250-sThermal Arc 161 and 300MM210DialarcTried being normal once, didn't take....I think it was a Tuesday.

Reply:You have a "valley" between your cap stringer beads. Use a slight but consistent side to side or z motion and hold the sides for a second to eliminate the valley between beads and blend them together.When you get to the top, things get real hot. That's how it is with vertical up stick welding. Turn the heat down very slightly (like 3 amps) , keep a short arc and you will keep the top in order.Last edited by snoeproe; 01-29-2016 at 07:23 AM.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720
Reply:Pretty much what snoeproe said- widen your stringers a bit so they tie in with each other, and pause a little (and I do mean LITTLE) at each side to prevent undercut. You want to run uphill and overhead fast, while flat you can often get away with running much more slowly. You might also want to work on crossing the middle as quickly as possible to keep things flat.On the issue of weld order, I was always told you're supposed to go from left to right (or the other way if you're a lefty). YMMV- the WPS is usually more important.Currently working as a Paralegal, but still interested in hobby welding.Miller Bobcat 225ntOne- Character Fractions: ¼ ½ ¾ ⅛ ⅜ ⅝ ⅞

Reply:Ran the bead up the middle and ground out the top and repaired it with tie ins and beads.  Happy with the center bead, but not so much with the repair.  I'll try some beads and tie ins on the other side and see if i can get some more pics up. Had a hard time with these.Thanks, Phil Attached ImagesLast edited by Phil Snyder; 02-01-2016 at 10:23 AM.
