Structural Steel beam flange plate connection. Steel fabrication & Mig welding.

[@BigPowerAL]

As an ole facilities engineer and recent new welder, I have respect for good competent welders like yourself. You make it look easy. My welding is more like metal gluing. No stacking dimes yet. I will get there though! Practice makes perfect! God bless!

[@TheMetalFabGuy]

Thanks for watching Alan. Good luck with the welding and practice most definitely goes a long way. As does settings. So play around with your machines settings / wire speed and you’ll get a feel of what’s right for your gauge of material. All the best .

[@Weldor123]

You don’t stack dimes on structural unless you want to fail UT

[@thebob3712]

stacking dimes? thats for people who cant/ don't know how to set their welder to the right settings to get a good weld,. Its all about the penetration not trying to impress someone with a weld that looks like tig welding

[@noteasybeingcheesy2673]

Sounds like you were already welding the right way. Mig welders aren't really welders anyway.

This is exactly how you are supposed to weld mig. No more stacking dimes because that’s actually a cold lap poor weld when you stack dimes. Nice work you could have welded for me ! I’d turn you loose and walk away and come back on payday to pat ya on the back!

Hi sir I am from India professional I am a engineer sir i saw your steel plate weld video nice information

[@larrylackey4156]

Everyone, this video shows some nice layout and fitting but there are some huge issues here. Short arc mig which is the process being shown here is the least penetrating of all wire processes and especially when pushing your weld. This process and technique should never be used on structural steel fabrication. Clean weld surfaces no matter your process is an absolute must for the best quality welds and always remember that your customer is paying for and therefore deserves the best possible job. I do not know what this particular beam and connection are being used for but if it is under any real stress loading where movement and flexing can happen, these welds are very likely to fail and break. This process is awesome for thinner material up to 3/16 or even 1/4 depending on application such as fences and gates and other non structural elements. Short Arc Mig should never be used in structural applications. Dual shield (flux core with gas shielding) such as a Lincoln 71m or equivalent and or straight flux core such as Lincoln NR232 or equivalent are your best options in manual processes for production. The welds in this particular video are well done in appearance but are not well penetrated and are brittle in comparison to what a true structural weld should be. Another thing in fabrication, all your small parts should be completely fabricated before being installed onto the columns or beams. Drilling after Welding if needed should only be done after the welds have properly cooled down so as to not allow an quenching of the welds by the drilling fluid/ cutting oils as this makes the welds very brittle and ultimately much weaker. Just to cover all the Mig issue, mig can be used but in a spray arc mode only and that process is to hot to work out of position so it is not quite as production friendly but is high quality when done properly.

[@munichrebel1993]

I never realized hardwire was a no no for structural until just recently moving out of state and starting a new job, we used to do this stuff all the time lol .. I've had issues with lack of penetration with hardwire and I hated it for stuff like this, but after running dual shield or 7018 it's night and day, no issues with penetration... that shop I left just really had a thing for doing everything with hardwire unless it was otherwise specified. Hardwire is fine for some stuff but nothing is more annoying than having to grind out welds. I did that when I knew it wasn't good enough and I got flak for it, while others would have just left it and called it good. Now I realize it wasn't me, there's a reason it's not aws d1.1 approved lol... glad to be out of there.

[@jakesutton8077]

You shouldn't, but its what everyone does. I do a fair bit of structual fab and while we go use dual shield when we can't get away with hardwire, (I.E. residential and less inspected jobsites) I'd say about 90% of our fabrication is hardwire. You do, however wanna push it if you're using it in these aplications. Plain wrong about that.

[@daywalker6847]

This guy..... Mr. Super presise.... Nice video... Informative and entertaining

[@grumpyone5963]

Pretty good job. A few points to consider maybe. If you grind off the scale, your annular cutter will last longer. I bevel the plate and weld in flush with the flanges. A pair of knife magnet strips works great for holding it in place. Also you should try 1mm wire. You will need to alter your settings but you’ll wish you had done it sooner when you do. I run 2 millers. 260amp with 0.8mm for most things and 450amp with 1mm for structural or higher duty cycle jobs.

[@TheMetalFabGuy]

Thanks for watching and taking the time to post your comments. Much appreciated.

[@davidrichards3605]

Dissagree, for this sectional thickness 1.2mm wire is more appropraiate than 1.0 mm wire, will give faster deposition, better fusion and cheaper to buy. For a jobbing shop 1.0 mm wire is probably more flexible but if the predominance are these type sections then 1.2 is more suiteable.

For all those who have questions think about it logically, and ask your self the questions about the work your doing, and you should be able to answered all you own questions, e.g. thicker metal, slower speed, or thicker metal higher amps and wire feed etc, just think about distortion and heat, as for making it look nice that's just down to hands on practice no one can teach you that bar your self, main thing I would say is listen to your welds as you do them,

Do you not clean the area of scale and rust first? New Welder Fabricator for 3 months and always been told to clean/prep before welding/tacking

[@AlphaBobFloridaOverlord]

You are correct, the area [ideally] should be free of scale and rust. However, the argument here is that the process is quite hot so it quickly burns through the surface layer. The scale and rust float up to the surface as slag.

to achieve accuracy, formation is not done in that kind of way. the plate is marked in advance, we place the reinforcement, weld it and place it in the element. movement from the axis of the plate holes to the length given by the project. by marking the plate in place, the ears of the ipe hea or heb are never the same, for example if we take a heb 400 above is 400 below is 405mm. so the sleeve does not measure correctly, and the holes move
