arc with caramic ring

Since diameter > 5mm and increasing welding times, an increasingly large and unstable welding meld excist. A ceramic ring must be used to secure the welding meld.

The ceramic ring supports the welding process by stabilizing and limiting
the arc, by forming the molten metal and by shielding the atmosphere. There is also the effect of slower cooling due to shielding, which has a positive effect on the welding structure.

The ceramic ring is placed over the stud before welding and removed by crushing after the solidification. Its main components are magnesium aluminum silicate and aluminum oxides, and it is outstanding for its high temperature resistance and resistance to thermal stress. As your system supplier, we assamble the suitable ceramic ring for your application. In this way, we always deliver to you the best combination of ceramic ring and stud.

The ceramic ring is suitable for use on construction sites because it can usually be welded using light stud welding technology and no heavy and difficult-to-handle gas divices. It also prevents blowing effects caused by environmental influences, such as wind.

At the beginning, the ceramic ring is placed on the ceramic holder directly on the bolt. Both together are placed on the workpiece. To start the process, the stud is first lifted from the workpiece with a low electric current and a pilot arc. After a short "holding time", the main arc is initiated, which melts the materials. The ceramic ring limits this arc and avoids blowing and dripping effects.

All in all the stud is lifted from the workpiece and then plunged into the molten metal of the workpiece during the set welding time. Here, the stud connects with the workpiece. Immediately after the device has been lifted off, the finished weld result is available.

At the end, there is the permanently welded stud. In the graphic, you can find a schematic representation of the welding process.
