Shear Stud

Introduction
The welding stud is designed to operate in coordination with the steel construction, steel plate, welding steel mesh, and cement-modeled object for using in tall buildings construction, bridges and a variety of steel structures.
It functions as a mechanism to prevent the slip between two objects occurred, improve the strength of the structure, and make the floor plate combine with the steel beam efficiently. In the recent years, after made an assessment, the industries in Taiwan and in the world recognized that it was the most efficient constructing method.
The mechanical characteristics and the quality requirement of welding stud

The position of rupture | The bar part of the welding stud (No rupture in welding part was permitted) |
Bending Test
According to the standard of AWS D1, 1, no crack in the welding part of the welding stud was permitted after the welding stud struck or bended by the steel tube (hollow tube) to be at 90 degree of angle of bend. No crack or rupture in the bar part and welding part of the welding stud was permitted after the welding stud was struck to be bent to 30 degree of angle
