How thick is the wall? Could you use hose clamps?

Hello all,
I am trying to clamp together a piece of flat steel that has been rolled. The steel gets within about 4" of being closed, so I must close the gap and then weld the seam. Does anyone have any recommendations on the best way to clamp a varying diameter tube?
Thanks

Consistency is a good thing....unless you're consistently an idiot.
well i think i now have a killer idea. however, i defiantly would like to hear other ideas. Hose clamps are out simply because of the shear size of some of the tubes that will be used ( i think the max is like 30" diameter). i think wall thickness can range from like 18Ga to prolly 3-6mm
Easy...rope around tube...twist to tighten. Use a broom stick to twist with, then you can wedge it on the floor, or foot to hold while you tack...with both hands free
Make some tabs with holes. Weld these tabs on both sides, back a little bit from the edge. Put a length of threaded rod through the holes and run nuts in from both sides until the edges are at welding distance. Tack the joint in several locations, remove the threaded rod, grind the tab welds and break them off, finish the seam weld.Originally Posted by sleepy23
The size of the tabs and threaded rod has to be chosen to match the material thicknesss.
An open mind is a virtue...so long as all the common sense has not leaked out.
ratchet straps would be quick and easy. depending on the thickness of the material being worked with you could use small motorcycle type straps or larger heavy duty ratchet straps.
Another aspect will need some consideration is the welding.
Depending on the length of the tube.
You will need to tack weld at frequent intervals and I would suggest a back stitch sequence to minimise distortion.
Just a couple of cents worth.
