Reply:I think this is an absolutely great place to ask a question.  You will most likely find someone who has already gone through the paces and found an efficient manner to accomplish the task.  If not you will be asking men and women who work with type of problem and would most likely be able to advise which way would be best and may offer insight to possible pitfalls for either option.I can't say as to what the best method would be.  I would pobably have laid it flat and run a sub arc or dual shield in spray using a trolley.  I am would also be concerned about the warp, twist, and flex.  it is possible to weld both opposing fillets on one side at the same time using a trolley and then flip and repeat.  it would minimize your variables on distortion I would think.
Reply:Before i got on with manitoba hydro as a pressure welder i worked at a plant that specifically made structural members for buildings all over the world. The flanges and webs were welded together automatically, whereas connection plates/ clips / lifting lugs / web seams / beveled flange sections / and stiffeners were welded manually by us.When welding the flange to the web we used a huge adjustable dual submerged arc machine. Their was two independant welding heads fully adjustable to the different widths of of various colums we sent through. Some as small as 200 pounds, up to 70,000 pounds. The column laid FLAT with a piece supporting the web and flanges as the column was fed through. I would imagine their would be tolerences for distortion but standing it horizontally such as the pictures youve posted would inhibit the MOST distortion. My recommendation is to lay it flat.

Reply:Looks like a Ogden welder to me , problem is D1.5 limits weld size in flat and horizontal to 5/16 of a inch and 1000 amps.Works for most usa bridge girders .Seen Highs, Haberlies, National Eastern,& Tampa Steel Erectors girder makers and am not impressed. We jig them flat in a home made jig , tack and postion weld at 45 degrees .We then weld with LA-75/860 flux.  900 amps 5/64 Tiny Twin LT-56/LT-7 tractors most position at 45 degrees works for us 103 years in busness Harris Structural Steel Co.

Reply:Slow we are welding over 35 lbs an hr with the tractor !!!
Reply:We position the girder at 45 degrees run the head vertical , and pour it in . EMT what is the PQR for that weld you have ??? See the spatter is this metal cored wire . In the USA all states require sub arc for all web to flange welds to be done full auto only . Many use Lincoln Squirtmobiles to conform to this running 5/64 or 3/32 wire . Watched a girder fitter at work ,took 6 men to run it and welded with a single 3/16 L-61 wire on both sides web vertical, .not very productive in my mind.
