Stud welding has now become a highly sophisticated technology. This specialty in automotive engineering places the highest demands on equipment, bolts, welding processes and metallurgy.
We have been mastering all these demanding requirements for decades and have the right products for all applications for our customers on offer - of course with all associated services such as commissioning, training, maintenance, service and spare parts supply. And all of that worldwide.
Stud welding systems from AVISTUD with redundant system monitoring fulfill the performance level “d” according to the requirement of the European Machinery Directive. A power source can be used for stud, TARC- and TARC-nut welding and operating up to 5 feeders. With the optional feed monitor up to 6 positions can be tracked and individually configured. The Power-Safe Mode allows low power consumption during idle state. The Weld Impedance Control warns when the maximum welding circuit impedance is exceeded.
With the different types of welding heads, every welding task can be fulfilled.
For the power sources, special requirements exist today in stud welding.
The different materials used in body construction require a high degree of flexibility and modern interface communication at maximum duty cycle in multi-shift operation.
Just the right requirement for our key products N4s and N4s-AC.
Due to the modular design, tailor-made system configurations of single or multi-point systems are possible. Each feeder can easily be converted to another type of stud by changing the feeder unit as requirements change.
The new stud feeder FSE 1000s is a further development of the proven and frequently used stud feeder FSE 100.
The new stud feeder FSE 5000s is a further development of the proven and frequently used stud feeder FSE 500 for seperating and feeding T-studs.
The modular and robust construction is service-friendly and allows fast cycle times. All connections and media hoses are compactly integrated in the head connection. The head connection is positioned within the interference edges and allows a quick change. Due to the compact anodized aluminum housing, the use of a protective cover is not required.
AVISTUD welding heads do not require a support leg due to the servo-electric path monitoring and reach thereby also complicated component geometries, such as beads, radius, concave or convex surfaces.
The Welding Head for the Smallest Construction Spaces
For welding on hard-to-reach points, such as tunnel-shaped sheets, curved edges or small-dimensioned hollow spaces.
Whether the wear reduction for robot-guided systems with the AVISTUD supply hose separation unit or welding similar studs with a welding head and two feeders with the AVISTUD stud switch: We make it possible.
The AVISTUD Speedport reduces the feeding time by pre-storing the next stud during the welding process close to the welding head.
For the robot installation of the hose packages, we also offer different solutions depending on the requirements and robot type.
The cleaning station is used in an automatic stud welding or Tarc welding machine to clean the welding heads.
By using inert gas, weld residues can accumulate in the gas bell, which must be removed regularly.
For this, the welding head is moved to the cleaning station and cleaned with rotating knives.
The welding residues are sucked off automatically.

The challenges in the material mix of modern lightweight construction vehicles are increasing and are subject to the highest quality standards.
AVISTUD offers all current welding studs as a solution for a holeless connection with the carrier material. Welding on special materials such as sandwich panels, aluminum or high-strength steels are used here. Full-surface connection, high strength and minimized corrosion are essential quality features.
Bolts of different size and shape are an ideal mounting aid for components and provide a task-ready, durable solution.
AVISTUD offers a wide range of different types of bolts. This concerns both the base material as well as the desired application and mounting options. Of course, we are also your partner when it comes to the new development of special bolts for your individual application.
If your desired bolt is missing in the existing versions, please contact us; we look forward to developing your bolt together with you.
Studs with coarse thread, also called fir tree studs, are designed for various fastening solutions, such as clips, cables and wires or other fastening components. Quick fastening of the plastic elements by simply pressing. It always creates a secure attachment that remains easy to dismantle.
Large flange studs are mainly used for components that require a large contact collar when mounting. The used torques are on the bolt and not on the base material. Deformation in the basis material is avoided.
Very good current flow is essential in modern vehicles. By a paint-tight nut a connection to the body part is made, which allows a high currents flow through a safe and paint-free installation.
For exact positioning fastening of clips in space-constrained environments. Different materials for different applications and high strength.
Welding stud with internal thread for special applications such. Fastening of oil filters, but also component fixtures as a special solution and bearing-tight parts.
Studs as positioning and mounting aid for larger modules. Perfect fitting during assembly. Reliable centering.
