So on Tuesday march 2nd my school is participating in a skills comp for welding. They give us peices we bevel and tack it up and than lay the beads they want which are specified on the blueprint. When i recieved the blueprint all was good, mostly 6011 roots with 7018 over but i than notived my worst enemy..... Vertical uphill with 7018 on a corner joint.. Anyone have any quick tips for this? i will be practicing today and tomorrow so i can try some things out. These 2 beads could be the difference from 1-3 or last.
Reply:I take it you are in a welding class at school?If so, have you attempted these welds in class?If not in a class, have you attempted these welds on your own?Either way, what issues have you had in the past with uphill welds?Hobart Beta-Mig 2511972 Miller AEAD-200LEMiller 250 TwinNorthern Ind.

Reply:Watch the puddle. Keep a tight arc... Without pictures we can't help too much, we don't know what you are doing wrong. BTW the 2nd is Monday, better prepare yourself!Airco Ac/Dc 300 HeliwelderMillerMatic 200 (stolen)Miller Maxstar 150STLMiller AEAD200LE (welding and generating power) Hobart MIG
Reply:Yeah im in a double period welding class, also attending college next year for it. I have attempted this weld uhhh..... twice and the comp is on tuesday so it could be interesting. Im heading to the shop today for some practice beads so ill take some pictures there. It seems i cant get the weld even going. it just puddles at the bottom. was running a corner joint at around 100 stressing out over these.
Reply:1/8" 7018? Try setting the machine a bit hotter, around 110-115amps. Are you sure the bead is sagging or is it just the slag you see?Airco Ac/Dc 300 HeliwelderMillerMatic 200 (stolen)Miller Maxstar 150STLMiller AEAD200LE (welding and generating power) Hobart MIG
Reply:bead was sagging. the first joint is 2 6mm plates making a corner. and the other joint is a 6 mm plate joined with a 9.5mm plate if that makes sense to you lol
Reply:Hopefully you can use 3/32" 7018 @80-85 amps. Expecting a lot to learn 1/8" rod on 1/4" plate in two days. In any case, when starting at the bottom, build yourself a shelf to start from. Two or three quick short tacks on top of each other. Clean and let cool between each restart. This will help disperse your heat when you start your vert. It'll be better to risk having a little extra build-up on the first half inch then to simply take off and fight it all the way.
Reply:A quick google will give plenty of video examples.Watch this guy. Look at the puddle, listen to the arc.Notice how he kinda traces the front edge of the puddle with the rod.Keep a steady pace.Adjust your machine so the arc and puddle act the way his do.Hobart Beta-Mig 2511972 Miller AEAD-200LEMiller 250 TwinNorthern Ind.

Reply:When testing I would run the tip of 7018 across a flat file to give the end a shinny finish to make sure there wasn't any coating affecting the start.As for the uphill vertical , try to make your 6010 /6011 first pass below flush leaving enough material so you won't have to carry too much metal with the 7018. Is this two pass only ?
Reply:When running an uphill weld, i always try to use the same method. I start my arc, keeping the rod 90* (up and down)to the joint. i adjust my amperage to give myself a good 3 second pause on each side of the joint without dropping the puddle. I work a nice tight arc and weave the puddle side to side. One of the biggest mistakes i used to make with uphill, i thought i had to turn the amps way down to keep from dropping the puddle. as i found out i was just doing more harm than good. Trying to lead the puddle with the rod seemed to create problems for me as well, thats why i try and maintaining 90*. Once i learned i was just stacking a weld on top of the previous weld, kinda like building a shelf to set the next weld on, it got a little easier. Anyways, hope this helps. Good luck!Operating Engineers Local 3Lincoln SA 200Victor TorchDewalt Grinder10 lbs SledgeWhat more do ya need!
Reply:It takes practice. There are several ways of doing it and without knowing your skill set, I don't know if anything is going to help you much other than practicing. Some guys pause on the sides while others just keep moving.
Reply:Fake a seisure and flop around and pee yourself come go time. I honestly dont think you are ready bud. A corner joint dont give you that much wiggle room unless its thick steel and correct heat, arc length and experience are what you are gonna need to do this perfect for a competition without globular meltdown. I hope you prove me wrong tho and youre practicing as we speak.I hate being bi-polar it's awsomeMy Heroes Have Always Been Cowboys

Reply:Just get some depends and you're good to go... they're supposed to fit like real underwear.
Reply:Way ahead of you buddy already got a few packs ready for the future haha, just to make things better today on my way to school my bus got hit and than caused me to miss my bus to my manufactoring shop so once again no good practice today.. hooray for people who dont clear snow of their cars and back into a bus
Reply:When you get a chance, and you have someone you know runs good vert welds go in his booth and close your eyes and listen to weld learn the sounds of a tight arc, then watch from about 3 ft (with Hood, lol) an look at the amount of light put out from a tight arc. Learning those 2 will get u far. Also as other gent said angle works good at 90 deg but can be + or - a few. I thought welding for years, when you think about Sex and not the Weld you have Mastered it,Gooooood LuckSent from my iPhone using Tapatalk

Reply:Isn't this an outside corner on 1/4 " plate? No weave to speak of.

Reply:todays the big day boys and girls with little practice i come to sweep skills 2015 right out from under their nuts, ill let you know the place i come in........ on the plus side i wont come last because i had to teach a kid whos going yesterday how to lay a stick bead flat lol
Reply:At the mill I was welding frame to support conduit one day. Howard, a hell of a stick welder came along and watched me burn a 3/16" rod. He offered a different concept. It isn't enough to stack beads. You've got to drill a hole on each side to anchor it. His weave is an arc so tight flux touches the work. When he gets to the side, he pushes the rod forcing the filler to penetrate deep into the work. Voltage falls to low levels, amperage rises, it won't snuff out, it's hot enough it won't stick. You drill a hole into which you deposit a fast freezing anchor.FieldRes (Travis Field) has a You Tube video talking about the value of a ratio of welder settings where voltage is low, amperage high. Most of us can't adjust voltage except with very short arc length. Try that mental image, you aren't just stacking beads, you're drilling a hole in which you place an anchor at each side of the weave.An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.
Reply:How'd it go today jabab?Well I did alot better than I thought I would. Came 4th out of 15 people. Still get my Linde prize pack at the award ceremony. Vert ups were gross but everything else just seemed to click and looked amazing. Pretty proud of the results they argued over mine and the 3rd place project for over 45 mins until they came to the decision

Reply:My 1/4 corner joint wasn't so big. I should have just ran it up and not weaved it. Weaving it tore apart my edges and turned out god awful. I tacked my project up and had a horizontal 6011 root with 7018 fill V gap and so much heat made tacks break and it bent out which also deducted me points. Also didn't know that TYP on a print means typical in this case i was supposed to weld all of the in and outside base and i didn't, if i would've it wouldn't have tore off and probably would've gotten 3rd
Reply:If you tore up your edges when weaving you either didn't pause long enough on your edges or you simply used too much heat or both.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720
