Southern Stud Weld is an industry leader committed to developing innovative solutions in stud welding operations. With decades of experience, we understand the importance of strong, reliable fastening solutions in various industrial markets. Stud welding produces one-sided, welded joints that are more durable than the parent material, making it an ideal process for fastening and assembly in construction, fabrication, and manufacturing processes. Our inventory includes stud welding solutions with cutting-edge technology and innovative developments designed to meet industrial requirements.
What is Stud Welding?
Stud welding is an electrical welding process that securely joins a weld stud fastener to a base metal material. In this one-step fastening process, an electrical arc generates enough heat to melt the fastener and parent material. Then, the weld stud is pressed into the molten metal, producing a high-strength connection.
Other welding processes may not be as fast, easy, or safe as stud welding. When compared to other welding methods, stud welding only requires access to one side of the workpiece and does not call for high-pressure equipment. More efficient and cost-effective, stud welding can be used in applications where other welding processes may not be for speed and reliability.
How Does Stud Welding Work?
In stud welding, an arc is created between the stud and the workpiece. The stud and base materials are melted and then joined under low-contact pressure. Stud welding takes less than a second to produce a leak-proof, load-bearing connection. There are two methods to stud welding operations: capacitor discharge (CD) and drawn arc.
Capacitor Discharge Stud Welding Process
Often used for smaller weld studs and thinner base materials, capacitor discharge stud welding produces an arc from the rapid discharge of electricity. Capacitor-based welding won’t thermally distort, discolor, or burn through thin materials and works with dissimilar metals without complication. The procedure for capacitor discharge welding is as follows:
A weld stud is placed against the base material. In this process, the weld studs usually feature a special tip for precision weld time control and consistent, automatic welds.
The stored energy in the weld gun is discharged through the weld stud to melt the total diameter and part of the workpiece. Spring-loaded forces insert the weld stud into the molten materials.
As the molten metal solidifies, a high-strength fusion weld is created between the stud and parent material.
Procedures for Drawn Arc Stud Welding
Drawn arc stud welding best suits large-diameter weld studs and thicker, more rugged base materials. Ideal in structural, heavy-duty applications, drawn arc stud welding is accomplished in one of two methods: standard and short-cycle.
Standard drawn arc stud welding uses flux-loaded studs and ceramic ferrules that contain the molten metal during the welding process, forming a fillet around the stud base. This process uses studs with a 1/4” (6mm) diameter or larger and base materials with thicknesses of at least 1/3 the stud diameter. Short-cycle drawn arc stud welding has a higher weld current and shorter weld time for a lighter fastening process that produces less molten material, eliminating the need for ceramic ferrules. This welding method accommodates studs with a diameter of 3/8” (10mm) or smaller, and base materials as thin as 1/5 the fastener diameter.
The drawn arc stud welding process is as follows:
The weld stud and ceramic ferrule are pressed to the parent material using spring-loaded tension from the weld gun.
Automatically lifting the weld stud when triggered, a controlled electric arc is generated to melt the stud fastener and workpiece material. In standard drawn arc welding, the ceramic ferrule retains the molten material and concentrates the heat in the weld area for strength and reliability.
When the weld stud and base material are melted, the weld gun uses spring force to press the stud into the molten work surface, and the metal solidifies to create a high-quality fusion weld.
Advantages of Stud Welding
Stud welding uses a fast and efficient process to create welded connections. Compared to other methods, stud welding offers a host of benefits that improve fastening strength and reliability to meet application requirements. Manufacturing, construction, and fabrication processes benefit from stud welding due to:
Fast, near-instant joining process
Secure, permanent fastening
One-sided for aesthetically superior joints
Does not require drilling or tapping
Maintains the strength of parent material
Produces leak-proof, load-bearing connections
User-friendly equipment and processes
Cost-effective and efficient results
