Yes, it is possible to weld stainless steel to steel using stainless filler rod, but you will run into a few problems: the 2 materials have different molten temps, so to make a consistent weld puddle will hard, the grain structure of the 2 materials will be different, so it is almost guaranteed to have a lot of stress and want to crack, and if you got past those to, the fact the "pure" stainless steel was molten with regular steel, they will mix and eventually rust, since the properties of the steel will have transfered to the stainless.
there are 3 types of welded joint 1-butt weld butt weld is the type which need usually 4 mm clearance between the 2 edge of pipe or plate you want to weld it. 2-socket weld 3-seal weld
Disclosed is a method for preventing hydrogen-induced disbanding of austenitic stainless steel cladding, which is made on a low alloy steel, in a reactor vessel which has been used in a high-temperature and high-pressure hydrogen atmosphere so the air must be excluded. The clad steel is cooled from its operating temperature to a temperature which is not lower than 100° C. Then, the clad steel is maintained at a temperature between said temperature which is not lower than 100° C. and a post weld heat treatment so as to effect hydrogen degassing treatment. Thereafter, the clad steel is further cooled.
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.
The most common types of rods used for welding stainless steel are 308, 309, and 316. 308 rods are best for welding 304 stainless steel, while 309 rods are recommended for welding 309 stainless steel. 316 rods are suitable for welding 316 stainless steel and are also good for general-purpose welding of higher-grade stainless steels.
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.
Silicon is added to the tig rods in production. Use a gas weld rod which does not have the silicon and the weld will be full of porosity.

You can use the 308 or 316.
stainless steel contains chromium. chromium gives off toxic fumes when heated.
yes
No, I can't.
The 300 series electrodes, rods and wire were developed to weld stainless steel. Ex. 302 304 316 327 etc. Electrodes will also be designated as -15 or -16 (Ex: E316-16) and sometimes LC or ELC (Ex: E316-16ELC) The filler material should match the type of stainless to be welded, esp. 316 as that is food grade, but just for repair work almost any 300 series will work on stainless steel. Rule of thumb, the higher the 300 number the better quality the stainless. For welding stainless steel to carbon steel 309 is recommended.
It depends on the type of stainless steel. Stainless steels come in various compositions and are identified by numbers and letters. Electrodes should be chosen that match these. For example when welding 316 stainless use type 316 electrodes. In a lot of situations you can safely use the next higher number. 304 stainless can be welded with 308 electrodes, 308 stainless with 310 electrodes. 309 electrodes are generally used to weld stainless to carbon steel.
