IKING Arc Welding Stud Bolt for Steel Structure

What Are PSR Studs

Punching Shear Resistance Studs (PSR) are large headed punching shear connectors that are welded to flat steel bars (creating stud rails) and are used as punching shear reinforcement in flat concrete slabs to replace abutment stirrups and column capitals and resist punching stress in the slabs.  

Structural Function

Uprights of predetermined length and diameter, as per design specifications in accordance with IBC and UBC structural steel welding standards, are used to extend the perimeter of the column in the floor slab or foundation slab.

Welding Process

Drawn arc stud welding for shear connectors can be done mechanically or automatically, using welding guns or welding heads. The shear stud is inserted into the stud holder and – fitted with a ceramic ferrule, if necessary – applied to the workpiece. At the beginning of the welding process, the stud is lifted by the mechanism and, normally, first a pilot arc, then the main arc, is struck between the tip of the shear stud and the workpiece. This causes the face of the stud and the parent material to melt. When the welding time has elapsed, the shear stud is plunged with little force (< 100 N) into the molten pool, and the current source is switched off. The ceramic ferrule is then removed. Figure shows the sequence of events using a ceramic ferrule.

Production Advantages

Features:

Made by high quality low carbon headed steel wire, make suis automatically embedded by unique equipmentre shear studs mechanical properties and welding properties, no cracks on the studs' heads. High precisioensuringn multi-station cold forming machine, ensures high precision and constant shear stud dimensions, round chamfer at the end of the studs.
High precision dimensions make the shear studs easy to load into the welding gun chuck and hold tight properly; Flat weld end with round chamfer makes the shear studs easy to insert into the ceramic ferrule hole, and get 360 degree perfect weld collar.
Accurately calculated aluminium flux embedded by unique equipment automatically, ensure the welding quality and avoid cavities in the welding bead.

Surface Treatment:

IKING shear connectors used high-quality low-carbon steel proceed by pickling and phosphating, ensure the studs have long time anti-rust condition.
