Many kinds of fasteners are utilized across industries, from bolt systems to rivets, and different types of stud welding are among those hundreds of fastening systems. Stud welding is implemented in many different fabrication instances for a fast, clean, and strong connection. If you’re working with drawn arc, capacitor discharge (CD), or short cycle stud welding, you can find everything you need at Northland Fastening Systems (NFS). We provide a comprehensive supply of tools for rent or purchase, studs in a complete range of dimensions with custom sizing available, and accessories. We also have an expert staff that can give technical guidance, advice, and support. Stud welding fastening systems are more effective, stronger, longer lasting, and more advantageous than several other connection techniques for a variety of reasons.
Other Fastening Systems
If we look at some of the following other fastening systems, we can determine their disadvantages and see why stud welding might be a better solution depending on the application.
- Back welding: Back welding requires holes to be punched through the surface and deburred for a cleaner finish. When the weld is complete, the result needs to be sanded and smoothed further for a flat connection point. This process is much slower than stud welding, and the punched holes weaken the surface material. On the other hand, stud welding doesn’t need any prior hole punch, and creates a clean finish by default.
- Drilling and tapping: This process only works effectively on thick surface materials with longer studs. Because the drilling and tapping process requires several preparatory and finishing steps, it’s also slower and more constrained in application than stud welding.
- Inserts: The main issue with inserts is that they begin to loosen over time. They are also prone to crack paint-finished surfaces and leave stains as they corrode. Inserts require punched holes that weaken the parent material and require a deburring step before inserts are installed, and the reverse side of the connection point is often not clean. Stud welded points are not only faster and cleaner than inserts, but also they will never loosen. In fact, either the stud will bend or the surface material will crack long before a stud welded connection point loses stability.
- Bolting: While through bolting can create a strong connection, it also requires hole punches through the surface material and deburring of those holes. Technicians installing a bolting system need access to both sides of a surface for two-handed assembly. Installed bolt heads are bulky and often leave stains on the parent surface. A bolting assembly can leak when exposed to liquids, and the punched holes weaken the surface material.
For the majority of applications where stud welding can be used in place of these other fastening methods, it will be to your advantage to implement a drawn arc, CD, or short cycle process. Stud welding is faster, cleaner, less invasive, stronger, cost-effective, and flexible than many other fastening methods.
