Welding partial bottom piece at the rear Options

[Leon.paradise]

Hello,

I would like to replace and weld in part of the floor panel at the rear of my 914. I have a question to which I have not found an answer on the Internet. When I weld in the floor pan I have to completely remove the 2 plastic fuel lines (flow and return) from the tunnel or I can leave them in when welding the floor pan. I am specifically concerned with the risk of fire. The heat when welding sheet metal can cause the fuel lines to melt or the heat to make the lines so hot that what can happen. The engine and tank are still installed in the vehicle as normal. What about the engine and tank, can they be built in or do they have to be removed before I start welding.

The carpet, seats, seat back wall will of course be removed by me beforehand.

Greetings Leon

I'm using flux core on my 914 restore currently, mainly as i'm working outside where the wind would cause problems for gas. Agreed gas is better, cooler cleaner but flux core is do-able.

what i find works is, 0.8 mm wire, a welder than has ability to to set amps low (15-25 amps), good stich welding technic and of course your friend the grinder to correct where its not gone right.

Also for flux core the body is clamped to the negative terminal, positive to the gun - this reduces heat & splatter.
