floor welding

Post by stag36587 »

Hi there
Been doing quite a bit of welding recently - both chassis legs in successfully as well as front cross member. I'm now welding in the driver's side floor and have hit a snag. On the photo can you see where the rear of the seat floor joins the existing metalwork. Anyone got any tips on how to hold this particular piece really close together - and indeed the floor to transmission tunnel - whilst I weld? The original metal is quite strong and springy!
thanks<br>Image<br>

Or pop rivets. You do get fancy devices like re-useable pop rivets - can't remember the name at the moment - I'm sure someone will come up with it in a minute. But pop rivets work well enough - just tack in between, and then remove them. The other option (and some will say better) is to butt the panels closely together with no overlap - you can secure them with magnets while you tack them up - or tags which you remove after welding. If the welding goes well - you can buff it all down and the join becomes 'invisible'.

Ive got a set of Very strong magnetic clamps, they worked very very well. So well it was a bit of a mission to get them off again......I did a bit of maths and found out they had a strength (flux density) of about 0.8 Tesla, which is a lot!!
Ultimate rust cure for your moggy....paint it brown, at least that way you dont notice the rust as much!!

Ah yes clecos, though the magnetic clamps sound excellent too. Thanks

We use self tappers, and I'd be wary of butt welding the floor, a slight overlap is a far stronger joint.and less prone to splitting with the movement of the seats and folk getting in and out.

I agree -I would overlap and weld both sides - but many others here insist that just forms rust traps and is 'not right'!
