SOYER®’s quality concept “Fast-Safe-Reliable” is applicable through their entire stud welding range, which includes various types of weld studs, weld pins, welding machines and accessories. Weld studs are commonly used in various industries covering a wide range of applications such highway, bridges, switchgears, lifts, coffee machines, kitchenware along with other applications. Our offer spans the complete weld stud range, CD Stud, SRM® HZ-1 Stud and Drawn Arc Stud.

Features:

  • Hole-free & one-sided welding process for limited access applications
  • Higher strength thanks to three grades of carbon steel, 4.8 – 5.8 & 8.8, available to address most of application constraints
  • One-sided installation, easy for limited space application, invisible mark on panel A-side (CD & SRM®)
  • Special design includes studs for earth connection and nails for insulation
  • Weld joint is stronger than either the stud or parent material alone
  • Higher corrosion resistance is achievable through A2 & A5 stainless studs

  • CD Studs
Soyer CD Studs
This is a commonly used welding technology. When welding the stud on the workpiece, tip ignition is crucial. The molten pool created by the main arc connects the stud and workpiece into a thin melded zone. Stud will be immersed in the welding area so that it can be connected with the material through the arc welding process with little weld penetration. Happening within a fraction of second, a capacitor discharges energy which is used to melt both the studs and workpiece creating a thin bead formation.
CD technology enables welding of aluminum & copper panels, widening the assembly possibility. Applications can be found in vehicle construction, decorative metal and sheet metal industry.

  • SRM® HZ-1 Studs
Soyer SRM HZ-1 Studs
The newly developed technology SRM® aims to replace various joining methods such as gluing, riveting and clinching depending upon application requirements. It is also the first time that HZ-1 stud enables universal use of the same stud for all known stud welding processes. This welding process uses a radial symmetrical magnetic field in conjunction with HZ-1 universal weld stud, so that the end surface and centering tip will be safe and clean after welding. Arc will be in a spiral through the symmetrical studs. The innovation lies in the magnetic field which guides the main arc to ensure a perfect, symmetrical melting of the stud & workpiece material. The advantages are multiple. When welded, the stud will be immersed flatly in the penetration zone and will not be separated. Through the whole welding process, ceramic ring is not required.

Through this unique and patented innovation, it is now possible to weld thin sheet panel with SRM®. The stud diameter to plate thickness ratio is now 1/10 as compared to 1/4 with classic Drawn arc welding. Overhead welding is now enabled, and automation becomes much easier and cost effective. Dissimilar assemblies are now possible subject to performance testing. After application, the material has nothing changed of deformation or distortion, or any tiny visible mark from welding point. It helps to minimize the corrosion problem. To assemble various materials to the workpiece is now also available.

  • Drawn Arc Studs
Soyer Drawn Arc Studs
First stud welding technology is now widely used in heavier industries, such as construction, shipbuilding, structural and civil engineering. The stud is drawn by a spring mechanism contained within the welding gun, after which an electrical arc is created which melts the stud & workpiece. Once the material fusion point is reached, the stud is lowered down into the molten pool which creates the welding joint after cooling. Ceramic ferrules purpose is threefold. It helps to shield the arc from the operator, contains the molten metal then forms it into a fillet, and allows for weld gases to escape during welding process.
