Help with rv welding

Hello, I need help....

I am a new welder and looking to do some repairs to the underside of my travel trailer.

I notice that there is a lot of wood and other combustibles on the bottom of the traielr but I need to do some frame repairs.

What precautions do I need to take in order to weld and repair my framing?

Thanks,
Jay

That can be a little tricky. You have to lift the wood from the metal you're welding and shield it from the heat. This is no more than common sense. What can cause a problem that isn't so obvious, though are the fasteners that attach the wood to the frame. Some use a screw down system.

The problem is, when welding, the metal the screw heats up and transfers heat up through the wood and can start a fire that is difficult to extinguish. If you're welding in close proximity to something like that, I would take extra care to avoid heating the fasteners or clip the ones that could get hot.

I would lift the wood from the frame in the area of the repair, wet it some time before welding, and shield it with tin foil.

Hope this helps,

Bob
