What type of welder do you have? Whats the actual thickness of the sheet? Generally when you wire weld sheetmetal, you make a series of spot welds, allowing time for the welds to cool. If the metal gets too hot then it'll warp.

its a lincoln electric mig welder and i think the steel is a little less then 1/8inch

Not what I'd call an accurate measurement, certainly not what I'd call "really thin". Do you own a micrometer or vernier caliper?

The reason I ask, is that 1/8" or "a little less" should be a sweetheart with a MIG. Then again, if you're truly talking about thin sheet, say 22ga, forget it, not happening. Use rivets.

Is this metal thin enough to fold by hand?

okay sorry i probably shouldent have said really thin its not bendable by hand. I just dident know if all i needed to do was talk weld or if i should lay a beed all the way around. SORRY about that probably should have explained better

What do you need it for, I take it its nothing major so no need for a full bead.

i am just using is as a plate to go under the frame to keep my feet from falling

 

[Doc Sprocket]

Cool. Knowing that, I'd say weld the corners about an inch long on each side of each corner, and then run some 1" beads 6" or so apart along the sides.
