Hi all Worked at a dry dock on a Dutch type barge. Hull plating - finishing a "Y" intersection of the overplating, under the barge presenting overhead with the barge on blocks. Switched to 7018's Bohler "EV50"'s - 3.2mm - ran at just under 140A to140A ish. ie. top of recommended range. 2~1/2years since last used 7018's. Forgot how "nice" they are. Clean arc - could see so clearly. Lovely "fingernail" weld pool. Smooth stringering. Weld absolutely wanting to be done. Was able to stringer up to, in to and out of the intersection always with a constant ideally fluid weld pool. Weld I left in view delightfully smooth. Was smooth and placed exactly where I wanted it through the about 3 layers build-up too. I was left at a loss to understand why others had used 6013 wide-weave...?
I always remember the advice from late contributor here - 6013/Rutiles run-out at the rod length; 7018/Basics run-out at half the rod length. ie. you do half the weld length but twice the cross-sectional-area. Can result in different rod sizes for Rutiles and for Basics. I'd have felt the Rutiles had a fairer trial if I'd run big-dia. 6013's at high Amps to get the fluidity matching the plate thickness. But the7018's - the so natural way they flow-in for heavy steel jobs...!
