these are massive subjects (especially the effects of welding on different materials). you'll get far more responses if you ask specific questions- the general infomation you're asking about can all be found in a book or via google

google 'welding distortion' and have a read. here's one to get you started... http://www.welding-advisers.com/Welding-distortion.html

for distortion control methods google 'neutral axis + welding', 'backstepping + welding'

compared to mild steel, stainless has poor thermal conductivity and high coefficient of thermal expansion. as a result this material will distort more readily than mild steel. google 'stainless + thermal conductivity + welding' and you'll find articles like this... http://www.key-to-steel.com/Articles/Art97.htm

have a good read, try googling different terms and THEN ask specific questions about anything you don't understand- you'll get far more responses and most will probably be helpful
