Welding, bolts, or rivets: Which joint resists best when everything shakes? An analysis from fatigue and fracture perspective. In the previous two posts, we discussed practical advantages: when to use welded studs and when rivets are irreplaceable. But today we’re getting to the heart of the matter: What happens when these joints age, vibrate, or […]

Stud welding is a technology widely used in industry to fasten metal elements to sheets or structures without the need for drilling. This system allows studs, pins or fasteners to be joined directly to a metal surface through a controlled welding process that creates a permanent and highly resistant joint. Unlike traditional fastening systems such […]

n the previous post, we started an interesting debate: “Why welded studs are gaining ground on rivets and conventional fasteners“. We talked about execution speed, the absence of drilling, and how this technology is revolutionizing industrial and naval construction engineering. In engineering practice, selecting the correct fastener is a critical design decision. Although bolts offer […]

In recent years, rivets have been losing ground to studs. The reason is simple: studs are faster to install, more economical, and require less maintenance. But within the world of studs, there is more variety than it seems. There are threaded studs, plain studs, internally threaded studs, insulation pins, earthing terminals, and even special parts […]

We’ve been seeing it for years. Projects that start well, new equipment, experienced operators, and suddenly, studs that fail. They don’t fail at the moment of welding. They fail days later, when everything is assembled, when no one expects it to happen. Stud welding is not like conventional welding. When the arc fuses the base […]

The BEARFIX catalog is clear on this matter. While the LBS and PRO-C series are listed under the heading «Capacitor Discharge Stud Welding Machines», the PRO-D and PRO-I series appear as «Ceramic Arc and Short Arc Stud Welding Units». They are not the same. They do not serve the same function. And choosing incorrectly can […]

Selecting the appropriate metal joining process is fundamental, as it affects the structural viability of the project. There are several aspects to consider when deciding on the best joining method. Welded joints and riveted joints are two popular methods of permanent metal joining. Depending on the project, both welding and riveting have their pros and […]

At Bearcat we have been offering fastening and joining solutions for more than 25 years. One of our most representative systems is capacitor discharge welding, a precise and controlled fusion, ideal for thin sheets where marking the front side is not desired. Our main protagonist in this process is the PT type threaded stud, manufactured […]

At Bearcat, we know that the key to a great project lies in the strength of its bonds. During this year 2025, we have shared with you the challenge of creating precise and lasting connections, from automotive to civil construction. Just like a well-welded bolt, we hope these holidays strengthen the ties with your loved […]

The rivet has been both witness and driver of industrial progress for centuries. What began as hand-hammered copper pieces in the shipyards of the Nile are today precision components manufactured with advanced alloys and controlled by digital systems. This evolution is not only a story of materials, but of how engineering has responded to the […]
