I don’t understand why you have a backing plate, what purpose does it serve? All my certificates welds we were required to have a stop and start within the middle of the plate. We were told to make sure that the ends were all tied in properly no end tags were allowed. The tacks were to be in 5mm from each end and one in the middle. The root bead on the opposite side was not allowed to exceed 1.5 mm in hight max width 3.5 mm. No more than three passes for the filler run including the root run. Three passes for the capping run only. That was the required test for procedure for both the Horizontal and Overhead test pieces. To me that backing plate defeats the purpose of testing one’s welding skills.
The backing plate is there because this isn't a open root 6010, 7018 out weld. Open roots are never welded with 7018 for the root pass, at least here in the US. It gives a spot for the weld metal to bridge the root of the bevel, as well as allowing you to start and stop your welds a bit further out from start and end of your groove, allowing you to have an easier time keeping the entirety of your groove even.
@@austinhargett5792 I welded my certification test using 6010 root pass then 7018 fill and caps. All our training was done open root and we had to keep the final product flat so we needed to observe the amount of distort ion and make sure it finished flat. I used 7018 Kobi Rods
@@nonadjannomyous5733 It may be so that E7018 is no longer used for open roots but as a Dow Chemical welder from the 70’sit was, backing /chill rings were not allowed for Dow work. I used E7016 in the late 60’s to test 5”xhy open root but Dow stopped using E7016 because Murex couldn’t supply it any longer so Dow went to Atom Arc & Lincoln E7018 open root. All contractor welders testing for Dow were instructed to use E6010 roots and E7016 or E7018 fill & cap. The switch to E6010/11 roots for Dow welders came about in the late 80’s. Heck, we all-position qualified on SS and nickel open roots with stick electrodes during those years. I do know that those WPS’s are all tig root. All testing was done to ASME Sec IX and all pipe welding was in accordance to ANSI B31.3.
I am really enjoying this National Panhandler's Radio interlude here with culturally correct background music to stimulate the art of overhead welding.
Excellent video for what I think is a difficult procedure- I have a busted rotator cuff on my right shoulder, and while I could lay in a very good root and fill passes, by the time I got to cap my shoulder and so fatigued that I couldn't hold the stinger steady enough to maintain arc length and travel speed, so my caps were the week point. Besides that, I had a hell of time with restarts in this position- just had a hard time seeing where to tie-in for some reason. Didn't have that issue with vertical, but overhead was a problem for some reason.
Having run a test booth for a number of years which included testing and training for those hands already on the project I can say that I personally made sure that a welder finished a pass to avoid tie-ins in the body of the weld. It is a harder test really with an added skill of having to make an X-ray with tie-ins on top of all else that a welder has to get right. My method of training was to get a practice coupon at 8 or 9" to get used to going the distance and then when testing you're using a standard 7" coupon and it makes it easy to go the distance. Also, we should think about the Overhead weld and the first and foremost issue being that uniform beads are critical as a pass where I slowed down or got out of position in the slightest way leads to the bead building up behind the rod and gravity being straight down means each successive pass goes over that bump and adds to the overall mess and it's going to look like Damian's finished product ( which I should mention was brave of him to show us and I admire him for doing so) and that's about it... just thinking here as long as I'm going long, take Damian for example, 1. have him run 2 more coupons to handle the issues above and then practice 2. Do this practice on an 8" plate to finish off the week and then he would test out and pass, he'd do both a Vert and OH plate we send it out for x-ray and he'd pass. 3. He would then be sent out to the jobsite and work with a fitter and he'd do tacking and hangers, etc. for about 6 mos. and would get comfortable welding 8 hours a day. Tie-in's would improve during that time significantly and 4. he'd be sent to the plate crew where he would be doing production welding and might do that for 6 mos. and 5. he could graduate up to the shell plate crew and do x-ray work all day and if he passes muster on that he goes to 6. the top crews working on the heavy shell plate (this is on ships) and includes 5 chrome steel and other exotics with pre-heat and post heat treat. What you would have in about 2 years would be a very good all round welder that could do any x-ray work and work as a boilermaker or maybe an ironworker, (that's a bit animalistic) and make a very good career out of it. And make some good wages too. This is just one guys opinion.
It's definitely a different feel and you just need to get used to it. ALWAYS keep pushing up because that rod is burning. You almost don't even think about it in the other positions.
If I am using a partially used rod, i take my fingers n snap the smallest bit of the flux off the tip then when i go to strike it theres way less issue of sticking … at least thats what works for me
We are switching it back. We heard enough of y’all wanting the “old” style, we are hear to please. But we actually got a lot of good feedback on this series. That’s why it exists
Trying to get my d1.1. 3g but I need to slow down on the root I use almost the whole rod for just the root. This video is the best and will help me become a certified welder. thank you this guy is the best hahahahahaha
usually this orientation of plate is a test plate for certification, different tests can look different. the backing strip is gouged off and the main plate is cut into coupons that are bent to examine
