3000x1500mm table drawing stage

5mm will be good enough for the tubes but not the rail surfaces, weld some 10mm flat bar to the top tubes for the machining.

Sorry if I'm being thick here but would those require full welds all the way down or just spot welded?

I would say stitch weld would be fine.

Stich weld it, here's a little program that will help you out https://www.stitchweldcalc.com/

Make your weld beads about 50mm long with a pitch of about 150mm. the calculator will tell you how many are required per length.
Tip: Chamfer the flat bar on the underside where your weld beads will be and you'll get a stronger neater weld with less distortion.

Thanks for the link I'll check it out when I get back from work. Just to clarify, the cheap mild steel flat bar is fine right? There mild steel that's more silver buy has a code at the end which is very expensive or the black mild steel which is cheap?

Thanks
