First of all, if your welding on a gas tank while it still in the car I would think that the undercoating is going to be the LEAST of your worries. I dont know who told you that you could weld that up but they have lost their minds. Dont do that without taking the gas tank out and filling it full of water before you even start. I hope your still alive. Ray You're joking, right? This is not believable. I hope you didn't post this in hopes some other idiot would try it? Step away from the car, give the keys to a responsible adult.
The asphalt itself is, but if there are any cracks in as seems common, then water will get under. Cracks in asphalt can be sealed easily now with many good caulk products.
No, you will get the opposite effect. Some fabrication/welding needed to move the axle under the leaf springs, but it can be done.
Lava is molten rock escaping through holes and cracks (eg volcanos) in the Earth's crust. The molten rock when under the Earth's crust is called magma.
That is known as an "intrusion". The magma (lava) is forced under pressure into cracks and fissures within the older rock. There are some good examples of this type of formation in Yellowstone caldera.
What you should look into is an Elastomeric paint or an Epoxy floor coating. an Elastomeric Coating on a cement floor would be more effective in light traffic walk way areas (around a pool). This product has a very low sheen and dries some what rubbery and can aid in the non-slip factor. Where as an Epoxy Coating would be more effective under heavy traffic or weight (in the Garage). This product dries extremely Hard with a very high gloss finish and is very slippery when wet with out aid from sand/texture These types of coatings can be applied to any horizontal or vertical surface. Check the product label for recommendations as for use on floors. Not all products are suitable to be walked on.
Many problems can be experienced in welding including cracks, infusions and distortion. Generally these can be avoided by eliminating hydrogen, keeping temperature under control and controlling the atmospheric pressure of the environment.

no
TIG welding electrodes do not melt under most applications. Electrode means it carries electrical current. In MIG welding the wire becomes the electrode. In TIG and Gas Welding the filler material is called a rod. Stick welding uses rods called electrodes.
they hide under the sand under the sea or fresh water im 12 and i enjoy catching things along the way when i first cought on i was fishing and i was 10 i love catching things i like catching crawdads or crawdads
if it is under 400 days yes
Moisture under hairline cracks.
A glass pearl has a round glass bead under the pearl coating. A Swarovski pearl has a round Swarovski crystal bead under the pearl coating.
