Arc spot welds, commonly called puddle welds, are widely used for connecting cold-formed steel roof decks to their supporting members. These support members are typically hot-rolled steel beams or girders, or the top chord of open-web steel joists. A comprehensive experimental study of the tension strength of arc spot weld connections used to affix a cold-formed steel roof deck to its support member was conducted. The study investigated the key parameters that influence the connection strength: Steel thickness, tensile strength, and ductility; type of weld process, automatic or manual; cross section of the roof deck; loading condition, symmetrical or eccentric load; and geometry of connection. Based on the experimental results obtained from over 260 connection tests, equations have been developed that predict the tension capacity of an arc spot weld connection. These equations are easily applied and lend themselves to use by structural designers. © ASCE.
