Providing a solid, strong and effective option for connecting concrete to steel in any type of construction has always been a challenge. Standard types of anchors can be effective for smaller types of construction, such as attaching metal frames to concrete for houses, particularly when the anchors can be inserted into the wet concrete of the floor.
However, for other types of construction such as bridges and commercial buildings, there is considerably more shear force in play, requiring the use of specially designed types of anchors. This is where weld stud concrete anchors, also known as headed concrete weld studs, are an essential option for a secure connection.
How They Work
The weld stud concrete anchors are carefully selected based on the scope of the job and the required strength. Each of the anchors will be welded directly onto one side of the workpiece. Unlike drilling a hole and placing the stud through, this prevents any sign of the stud from the outside of the workpiece.
This makes it a very fast process to create the rows of weld stud concrete anchors required for the specific beam or metal part. Each is welded in place using an arc to heat both the stud end and the workpiece. A ceramic ring, known as a ferrule, is used to focus the heat and the liquid metal that creates the strong attachment with the workpiece to sustain and support the shear force.
Location of Welds
Most types of weld anchors will be smooth and unthreaded and the head slightly larger than the diameter of the shaft of the stud. While they are typically welded to the flat surface of the metal part, they can also be welded on angles, typically on the heel or the fillet as required by a specific component or part.
