hi again what can cause distortion and what are the methods of controling them, also what effects can welding on different materails, aslo what are the sources of weld defects

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
