The Reasons To Use Projection Weld Studs

Just like any type of fastener in use today, weld studs have evolved over time and to meet the needs of specific industries and applications. Different styles and designs in weld studs fill different niche requirements, which also means they are uniquely manufactured to provide a more effective and efficient stud weld process.

The Projection Weld Stud Design

The typical design of projection weld studs includes a larger, flat, round head with at least three projections, in most cases, that are positioned either on top of the head or under the head. The position of the projections with relation to the top or underside of the stud differs based on the specific type of use.

There is also a unique type of stud that features this same design basic feature. It is called a ring projection stud, where the underside of the head has a complete ring that protrudes slightly to create a complete fillet around the surface.

The Purpose

The purpose of the positioning and the design of the projections on projection weld studs is critical for the formation of a complete fillet or weld under the surface of the head. With just one projection and a larger head, the molten pool could not be significantly developed in the short amount of time required to avoid marring the workpiece. With the larger projections or the multiple projections is a potential issue that can be avoided.

The Benefits

For many types of applications, including the fabrication of heavy duty equipment, vehicles, agricultural equipment or similar types of applications, the use of projection weld studs allows for a durable, strong weld that can stand up to impact, shock and vibration.

With the use of these types of weld studs, the process can be fast, effective and provide full coverage of the surface between the weld stud head and the surface of the workpiece.
