Hi,

I have an upcoming project which will require some bending or "large" mild steel sheets which will be welded to a tubular frame. I will be attempting to create a set of dining chairs with a curved back from 1-2mm sheet mild steel and im wondering what the best process would be to bend this accurately by hand?

The radius would be around 20-25cm.
What thickness of sheet steel is actually possible to bend by hand. We have some 2mm plate at the moment and i cant budge it.

My second question is about welding the sheet to the frame. Previous attempts of welding sheet steel have resulted in melting holes in the work instead of actually welding. This was with 1.5 and 2mm steel and i assume i will have to go to a thinner sheet to actually create this dining chair.

I also only have access to an arc welder, How can i weld thin sheet steel without it melting?

Thanks,
Matt
