The Benefits Of Projection Weld Studs

There are two different types of weld stud designs. One is used for spot welding, which typically involves the use of resistance welding processes. The projection weld studs have small bumps or projections on the weld surface of the stud, which allows for increased fusion to the base metal through a downward force supplied by the action of the weld stud gun.

Typically, these types of weld studs are used with applications that require heavy duty stud welding and where the failure of the weld is not an option. Different sizes, shapes, and options in projection weld studs will provide different configurations for the projections, with studs with larger heads typically having groupings of three projections while smaller studs may have one or two.

These projections are designed to create the melted pool of molten material very quickly, then the pressure of the downward stroke of the stud weld gun immediately forces the stud into the molten pool to form a complete weld.

Ring Projection Studs

For some applications, particularly when there is a need for complete and water, gas and liquid type of seal, the ring projection stud may be required. This has a different design than the standard weld stud with a ring the projects slightly from the head.

This ring is completely around the head of the weld stud without any breaks. Through the stud welding process, a complete hermetic seal is developed, making it ideal to prevent leaks.

Across Surfaces

One of the advantages of projection weld studs is the ability to use the stud welding process across different surface shapes and angles. This offers greater flexibility and versatility on corners and edges as compared to resistance welding processes.

The versatility and the different options in shapes, sizes, and diameters of projection studs make these a good option for many different jobs and applications.
