Thanks, Lew. Since I posted my message, I found out that AISI as well as UBC have criteria for arc welding and seam welding. And it seems that a 5/8" puddle weld on a 20 gage deck can carry up to 360 pounds of uplift. Since you are designing in the high wind zones, have you found that mechanical fasteners are more reliable or welidng has been ok so far? Again,thanks for responding.

The Steel Deck Institute (SDI) has literature on uplift values for screws, puddle welds, and other fastener systems. They're in Canton, Ohio, phone 216-493-7886.
