Abstract: In order to study the welding property of cold-formed steel members, the mechanical property tests are developed on the specimens, which are intercepted from cold-formed lipped angles. Cold-formed steel members have two connection modes usually, the first is the welding of cold formed steel members with cold-formed steel members, and the second is the welding of cold-formed steel members with hot-rolled steels or steel plates. In order to study the welding property to cold-formed steel members of different kinds of connection modes, the two connection modes are designed in specimen tests. The research shows that the effect of cold-formed procedures of cold-formed steel members has certain effect to welding property. The influence degree of bending angle plates is more obvious than flat plates.
Keywords: cold-formed steel members; welding property; experimental study; effect of cold-formed procedures
