Shear Stud Connector ISO 13918:2008, also known as “stud welding”, joins a welding stud and another piece of metal together by heating both parts with a stud. The welding stud is usually joined to a flat plate by using the stud as one of the electrodes.
Shear studs are also mechanically tested. Bending tests are performed for each order after welding. Shear studs are also tested for elongation and tensile strength using our own testing equipment
Shear stud is regularly weld tested.
The test implies that the stud is bent to an angle of at least 60° or until breakage occurs.
Quality raw material
We choose the quality mild carbon steel from BIG Steel Factory.
Taking M13 for example
Being able to determine the chemical composition of the raw materials for shear studs is a must for a good quality end product.
Tensile and yield strength tests are carried out regularly for each order and test certificates are supplied on request.
- The sizes can meet the requirement of the national standard or ISO international standard. Some factories lower down the prices with beyond tolerances products in order to get an order. This way is not available.
- The material we choose SWRCH18A/ ML15A/, ML15. Because this kind of steel can promise good quality welding stud.
- The mechanical performance index can reach the standard. The tensile strength between 420N/mm2 to 550 N/mm2. The yield strength is between 400N/mm2 to 450 N/ mm2. The elongation is between 16% to 21%.
The product appearance detail is also perfect, such as the tail of the welding stud has chamfering; the shear stud connector did rust prevention before packing…
