4X4Poet is right on the mark. Regular primers may seem to be okay but down the road you run the risk of the paint peeling or rust developing under the paint.

For your welding work that will ruin small patches of previously sprayed primer-sealer, have the paint shop mix up some primer-sealer in an aerosol can so you can reapply to just the parts you've welded around.
Verify this with your local auto body paint supplier. The staff will likely know this info from experience, whether personal or with customers. Besides, they will give you the best recommendation regarding waterproof primers.
