How to properly specify weld studs for steelwise use with

Weld studs are produced in several materials, the most common of which are carbon or mild steel, stainless steel and aluminum. For carbon or mild steels, the American Welding Society (AWS) D1.1 Structural Welding CodeSteel, lists three types of studs based on use:Types A, B and C. Through-deck stud welding has specific stud size parameters. Load Tables For Unistrut P1000 & P1001 Unistrut 1. Beam loads are given in total uniform load (W Lbs) not uniform load (w lbs/ft or w lbs/in). 2. Beam loads are based on a simple span and assumed to be adequately laterally braced. Unbraced spans can reduce beam load carrying capacity. Refer to Page 62 of the Unistrut Engineering Catalog for reduction factors for unbraced lengths.

Type F, or Type S, GradeA, standard weight (Schedule 40), unless another grade and weight Scheme development:Details for portal frames using The weld between the haunch flange and rafter flange is normally made a fillet weld with a leg size equal to the haunch flange thickness. 1.4 Connection details There should be a sensible relationship between the bolt spacing, bolt size and plate thickness. An efficient solution is to make the plate thickness approximately equal to bolt diameter.
