Yes @rbhat, you absolutely can. I worked as a welder for years and worked maintenance at power plants and worked plant outages all over Texas and even at a refinery in Beaumont Texas and it is possible, but like Ed Beal said, you need to grind the galvanize off first. I've welded with it on, and with it ground off. Believe me, ground off is better, WAY better. That smoke will choke the heck out of you. LOL Ok, with that said, here's the deal, galvanized steel is usually just plain old everyday carbon steel that's been hot-dipped galvanized. So to weld plain old carbon steel to stainless, you HAVE to use 309 stainless welding rods that's either TIG welded or my favorite, stick welded. Stainless 309 is only for welding carbon to stainless. We've done it many, many times. Like Ed said, grind the galvanize back about an inch, and let a welder go at it. (-: Hope that helps, a welding shop should be able to hook you up. Just my opinion, I wouldn't TIG it though, those impurities from that galvanize will pin hole the crap out of your weld. Stick rod plain old arc welding it is better.
