Taking The Guesswork Out Of headed Stud Selection

There are very specific applications that require the use of head studs or head weld studs. This is not a general use type of fastener, and they are most commonly found in industries that deal with combination steel construction materials such as beams or girders with concrete slabs.

Role of the Anchor

These types of industries include those involved in the construction of buildings, typically the larger types of buildings from warehouses through to towers of offices, apartments or condos. Another industry that uses head stud anchors is the bridge construction industry.

In these cases, the headed stud is used to connect the steel frames with the concrete surfaces. The use of these headed anchors allows for fast and low-cost installation of anchors that will weld to the steel and harden within the concrete for a secure hold.

The result is a fusion or a bonding of the two diverse types of materials. This ensures that one cannot move independently of the other, eliminating the problem of the two materials acting differently to the forces of tension and compression for the structure.

Headed Stud Selection

The selection of the right headed stud for these types of applications is always based on specific calculations of the forces acting on the specific structure. In many cases, regulations and building codes will require the use of a specific type of anchor stud and even designate the placement of the studs.

In addition to the anchor stud, there is a ferrule, a small ring, that is used to hold the molten pool in place before the weld stud is pressed into the surface. This is ceramic, and it will be knocked off after the stud weld is completed. The ferrule is designed to match the weld stud diameter as well as the surface shape of the workpiece.
