The best way to successfully weld SS to MS or even Hardened Tool steel to MS is to use Magna 303 welding rod mfg by Magna Industrial, Australia. It has been tried and tested and is the only successful way to weld different steels and the weld has a tensile strength of 1,20000 psi, but these rods are expensive and suitable primarily for maintanence or repair welding

Yep, you can weld steel to stainless and you can weld stainless to steel. You can use steel or stainless welding rod in either case but the steel or steel welding rod will of course rust.
stainless steel
You can weld stainless steel to stainless steel using various welding methods such as TIG welding and MIG welding. However, it is best to get a professional to do the job. And understand that stainless steel does not weld very successfully under any circumstances - it will almost always, inevitably, break right next to the weld.
mild steel is heavier
Many stainless steels are stronger than mild steel. Stainless steel is also corrosion resistant to many different environments where mild steel is not.
carefully
No, mild steel is low carbon steel with no other alloys.
Per the attached related link, the density (hence weight) of stainless is slightly more than the mild carbon steel. Using about 8.03/7.84 ratio of density, for the same volume of material the stainless will weigh 2.4 % more.
You can use the 308 or 316.
stainless steel contains chromium. chromium gives off toxic fumes when heated.
