Specialized jobs require specialized types of material and equipment. For companies in the business of constructing bridges, steel, and concrete buildings or many other types of applications, having the correct type and capacity of stud welding equipment will be important.
However, it is also important to select the correct headed anchor studs. These are distinctive in their design and are usually selected based on the specific application and the requirements for the type of construction. Additionally, with specialized types of projects such as bridge building, there may be standards and regulations that stipulate the size and type of headed anchor studs that must be used.
Factors That Matter
The purpose of these studs is to prevent the shear force from causing the two different materials in the construction, the steel beams or girders, and the concrete, from moving separately.
When not anchored together, the two different materials will respond differently to the shear force, which will result in a downward bend in the middle of the span. When the headed anchor studs are in place, the two materials are attached to each other, creating a composite strength that prevents movement and provides additional strength.
To ensure the correct anchoring, the studs have to be of a specific diameter and length. This is based on the stud length after stud welding, which will be just slightly shorter than the length before the stud welding process.
The location of the stud weld, including for corners and angles, will impact the size of the headed stud weld to use as well as the specific type of ferrule. By talking to the supplier and knowing what is required by code for matching the headed stud, ferrule and the specific job requirements it will not be a complicated process.
