The effect Arc Stud Welding process parameters on the mechanical properties of shear connectors in composite metal deck constructions
Message:
Abstract:
Arc stud welds act as shear connectors in composite steel-concrete beam which are now widely used in the construction of roof of buildings. In this study shear studs 19 mm in diameter made of AISI 1010 steel are welded to steel beams and the effects of weld current, plung and lift heights , and arc time are investigated. Weld samples were characterized in terms of appearance, profile, weld penetration, strength and fracture location in bend test. The results showed the significance of the process parameters on the soundness and strength of the welded connection. It is also shown that weld appearance and just visual inspection cannot be regarded as a sufficient test for the day to day inspection of the stud welding work at site. It is also necessary and important to perform the site bend test at the beginning of each shift or round of site work as required by AWS D 1.1 standard.
