most common electrodes can be used with ac as well. the difference is that ac will generally produce a wider, flatter bead, with less penetration. this can be a benefit if you are welding thicknesses under mm, ac delivers more heat energy into melting the electrode and less into the melting the base metal...
entire thing. this will restore both the strength and the corrosion resistance. there are also mechanical designers and good mechanical designers. it may be challenging but, if you increase the section size (thickness) where the welds are, you reduce the stress on the haz just because there is more metal...
