Good quality fluxcore would be quick and mobile

I am current on MMA using an inverter with a lousy duty cycle, but I haven't used an oil cooled machine since college and thinking back its 26 years! Inverters were just making an appearance then.Rather buy than hire a welder generator? Have a look at the cost of a decent one new first as they aint cheap! Unless you have AVR on that genny then I should forget inverters a big old oil cooled should run sweet enough though. If its 20 yrs from when you did some work with MMA you will need to get back in the swing before you crack into such a job- trust me it will come back but takes a few days not a few minutes to get into important structural stuff.
MIG? nah, not outside on the farm at this time of year some outside stuff ok but rarely suited to farm work. It will take less time to put the welds in than it will to hump them about and get it tacked on this type of site anyhow in my experiance
I worked out I can buy in the steel blasted and primed for just under £1800 (2 portal frames 5.4m to the eaves, 1 portal frame 4m to eaves (step in ground levels), 7 floor beams, 4 eaves beams, 1 hoist support beam plus plate for gussets and base plates).If I had to make a whole barn on site, i'd be looking at doing it with a decent mig plant run from a genny and a welding tent or similar personally....
Have you priced up getting it welded for you? When you are set up for doing it, its incredibly faster than messing about in a muddy field with a stick set...always drill the holes etc yourself to save some dosh....
Same as drilling plates, what is a days work to someone without the right kit is half hour, or £20-30 to someone with it.
Its strong and quick.ive used outershield(flux core with gas) more than innershield on heavy wall pipe mainly.those are lincoln terms, esab call it dualshield I think and there are more id say.70 to 80,000psi tensile strength is all I remember figures wise.was likened to low hydrogen stick, but takes about 1/3 of the timeNever used it (sorry used it once and said never again, thought it was very poor but that could have been cheap wire and a bad machine) how is it with muck n stuff when you need a good weld on thick structural ?
he is a decent bloke probablyNot much there is there! All little beams, decent bloke would bang that out in a day by the sounds of it
203mm x 102mm 23kg/M universal beam for everything apart from the eaves beams which are 152mm x 89mm 16kg/M universal beam.What size beams/plate you using out of interest?
I got a free 30 day trial of Quikport and used that to feed in all my designs to see what sections it specified. I then upped those sections by 2 sizes just to make it bomb proof!I need to get someone to draw my frame up really. Calcs need doing for the hoist beams I want and the mez floor beam at one end.
Esab 15:14 flux core in a 1.2 is unreal for those applications. Good thing about it is you can keep it in spray transfer and the same conditions in all positions. Just point and shoot and it will be done in no time.Its strong and quick.ive used outershield(flux core with gas) more than innershield on heavy wall pipe mainly.those are lincoln terms, esab call it dualshield I think and there are more id say.70 to 80,000psi tensile strength is all I remember figures wise.was likened to low hydrogen stick, but takes about 1/3 of the time
Not really a MIG job! Outside on site... Diesel MMA set, oxy propane, mag drill with a broaching cutter and away you go!
Yes it would speed up the welding but only really if you are inside under a gantry crane and it is a production job!
One off in situ... MMA rules!
Running a voltage sensing wire feeder from a diesel welder is almost as portable as stick welding,as well as needing less skillPretty much my thoughts but I am interested in what weresmejumper has to say about this duel core with an outer core, especially with strength equivalent to a 7018. I had this "speed" conversation on site with a guy recently and demonstrated to him that although MIG might well be faster in the weld set up times took the major amount of time even though I was putting in some long v up runs and I also had a great deal extra portability working at the foot of a steep muddy slope
My issue is on site on farmland you can have a lot to deal with with limited equipment and its the humping stuff about and improvising were time is gained or lost (oh and turning off and running for cover when it rains unexpectedly is a bit of a bummer!
