welding base plates

[Am333rcr]

hi

you will see that i have my shed base plates set. i want to weld to the end of beam.

is there any thing i should considers as it around 20mm going onto 6mm.

i was just thinking 3.2mm rods with 3 runs?

What size are the UC’s? 3 runs stick will just make them distort like mad. I see no need for anymore than 6mm fillet welds when the uprights are 6mm (presume web not flange).
If you can do two columns at once clamp the base plates back to back and weld both equally to counteract the pull of the others. A bit of shim stock taped in the middle to give an extra bit of pull may be required.

20mm baseplate are probably overkill. I’d warm them up a bit if you want to be 100%. 100°-125°C preheat.

“Overkill?”

i think the boffins call it “engineered with a significant safety factor”

Or under engineered

I'd go for beam flange thickness plus up to 20% or something like that. We put some temporary steelwork up on site which I'm just dismantling now the work is done. One of those props was carrying up to 100 tonnes and I think the base plate was only 20mm.

10mm base plate is loads for that job. One run of a hot 3.2mm rod is plenty. If your multi running you will be straightening it with a sledge
