welding a boat
going to look at a couple of welding jobs on a steel house boat,nowt major or near the water .
as it,s a steel hull and i intend using my trusty arc welder from their mains electrickery supply,is there anything i should be aware of and if the
bulkheads are double skinned,will they have some sort of insulation in between?

You'll soon enough find out John 
Once did some sills on a friend of a friends Orion for MoT. Stood up to admire my handy work and realised the passenger door card was on fire - a
little bit. Passed the MoT OK though

Been there, welding the roof patches in on our chevy.. Slightly melted the interior a little bit.
As for the welding on the boat - Are you using the mains power ON the boat? Or an external supply? I'd be dubious as to wether using the mains
on the boat might fry things, but I'm not sure.

If you are inside it wear your wellies and gloves so you don't earth yourself.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I have never welded a houseboat, but have done a few ships down at Falmouth Docks. Be careful of cutting out sections, they can be under tension and
will spring out and smack you in the face. If you are using DC, watch out for arc blow if the earth is a long way away from the work area.
If you wear wellies, then wear leather spats so you don't get spatterballs between your toes! Stand on old car mats and don't let your
gloves get wet, cos if you do,AC will give you a significant tremble, DC will lock your hand the the work - dodgy
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

John, Be careful of welding if you can't get in to see the back face. Spaces in boat hulls can build up methane and hydrogenous gasses, from
marine organisms going dead. The local boatyard managed to blow a big hole in the bottom (and top) of an ali hull just recently. The
'tank' was allegedly fresh water, but unused. Some seawater had got in, and... lucky the ali just split. Steel can be worse, or so the
experts and old boys say.
Just make sure the back is well ventilated, before, during, and after welding.
Cheers,
Nev.

Hi.
If Calor gas has been used for cooking be aware that being a heavy gas, any spillage collects in the bottom of the hull.
Arc welding spatter has a mind of its own.
Many a Norfolk Broards cruser has gone kaboom, fag end down the hatch etc.
Cheers
