6010 downhill

admin

So today in class I was tasked with welding the inside corners of our new plasma cutting tables. I wasn't quite sure how to do it but was told to make a small weave on my way down. So how does it look? Last edited by bbertb; 01-09-2015 at 06:26 PM.
Reply:If you ran a wire brush over it we could see the weld better. From what I can see it looks like you might be a little hot, or just a little too long of arc length. I don't do down hill, but here is a down hill pipe weld a friend of mine made.

Reply:I'm not familiar with that machine. Like I said I don't do down hill. I run 1/8” 5P-Plus up hill around 85-amps. I really believe people under estimate the skill it takes to run down hill. When you see the size of the rods, and the amount of iron pipe liners carry, then you'll understand their skill level.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:Remember with 6010, it's all about arc length! Close arc length is a colder puddle, and most times that's what it takes to stack. A longer arc length means a hotter puddle. Which means a more flowing puddle, harder to stack with a hot puddle. A machine with arc force really helps with the wetness of the puddle with 6010.

Reply:Play with the arc length. You'll be amazed at the control you have over the puddle, by controlling the arc length. 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:Actually downhand 6010 is fairly easy to pick up for general welding. Run a little hotter than flat and use a slight whipping motion to basically pull the weld down with you. Whipping helps control the puddle and weld size. Looking at the OP's picture, it doesn't look like he's getting a lot of penetration when you look at the crater. Pipeline welding is a little different as they run really hot and basically drag the rod on the pipe. If you want to try something tricky, try downhand 6010 on an inside corner to inside corner joint welding a cone roof on a large oilfield tank. Because of the curve of the tank from 3 o'clock to 6 o'clock, it's tricky to master. Flat plate downhand is a piece of cake though. I did a lot of downhand 6010 as a 1st year apprentice welding rectangular mud tanks. Then when I moved to main shop doing round tanks, I had to weld a roof on thinking it would be just as easy... NOT! Only a few guys in the shop were really good at it. It was easier laying on the floor and doing it more overhead than downhand on the curve. Downhand you can go further with 1 rod than in the flat position.CEP, that weld your friend did is a bit odd that the last bead is down the middle. Even with 6010, I think the beads usually go from one side to the other. I wonder if there was a bit too much of a valley in the middle?Last edited by Welder Dave; 01-10-2015 at 12:46 AM.

Reply:The type of cover pass (cap) you see in the photo was developed in the UK.  The last pass down the middle of the weld is called a stress relieving pass.  It was developed for welding on pipelines with a yield strength of X65 and higher.

Reply:Just a random question. Would it be easier to run down with more amps or less amps?

Reply:Originally Posted by geezerbillPretty much exactly like one would expect it to look, when done by someone in welding class, who had never tried it before.:-)No offense, it's just that there is no teacher like experience.When I have had the need to run 6010 downhill, I ran it hotter than when flat, and considerably hotter than uphill.As for technique, my whip (when used), was little more then a wiggle, and was added, just to attempt to keep the weld from being concave.On pipe, especially larger, or heavy walled pipe, we'd use 3/16 6010 downhill, with no whip, except foe the cap, and it got the wiggle.
Reply:If run hot, and at a not-too-slow pace, the bead will flatten out, not leaving the likelihood of slag or lack of fusion at the edges.When successfully accomplished, a wire brush or wire wheel is all that is needed between passes.You will most likely deposit less metal per pass running downhill.:-) edited to overcome auto-correctLast edited by geezerbill; 01-10-2015 at 12:31 PM.Hobart Beta-Mig 2511972 Miller AEAD-200LEMiller 250 TwinNorthern Ind.

Reply:You ALWAYS need a wire wheel on a grinder when your running 6010.....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:how is running your last bead down the middle gonna relieve stress?I've done them like that before. I think it's good for keeping your cap centered over the groove. If you go straight across with 3 beads you have a tendency to overlap farther on the last pass. Plus, it makes a nice transition height wise, a bit higher in the center sloping down to each side.
