Intro

Projection welding at a glance

In projection welding, workpieces are joined together at defined points by preformed elevations – known as projections. The components are clamped between electrodes and pressurised and the welding current flows specifically through the projections, whose high resistance generates local heat. This causes the projections to melt, join with the opposite surface and solidify into a strong welded joint.

Products for projection welding

  • Replaceable electrode for projection welding

    Replaceable electrodes

    Replaceable electrodes transfer current and contact pressure specifically to the formed projections. They ensure the energy input that melts the projections and creates the connection. Made from WIRBALIT® HF/N/G (CuCr1Zr).

  • Centering pin for projection welding

    Centring and positioning pins

    Positioning pins ensure precise alignment during projection welding. They engage in pre-drilled holes and position the components with repeatable accuracy at each cycle. Available in silicon nitride (Si₃N₄), zirconium oxide (ZrO₂, solid ceramic) or steel with ceramic coating.

  • Connection cables

    Connection cables transmit the welding current from the power source to the clamp with minimal loss. They are available as air- or water-cooled versions made of Cu-ETP or oxygen-free copper (OFC).

  • Lamella shunts for welding systems

    Lamella shunts

    Lamella shunts flexibly conduct welding current between the electrode arms and the clamp and compensate for movements during the welding process. They consist of stacked copper lamellae and are available in standard dimensions or as customised versions.

We keep your production running

  • With one of the largest warehouses in Europe, we deliver products in standard formats immediately. Thanks to our in-house development and lean structures, we are also capable of implementing custom solutions flexibly and promptly.

  • As an active member of the German Welding Society (DVS), we contribute our practical experience directly to standards and guidelines. This results in solutions that not just meet current regulations but also help to shape the future.

  • Together, we analyze requirements, identify potential for optimization, and implement concrete improvements to make your processes more economical. As we understand consulting to be an integral part of the production process.

  • Where standards are not sufficient, we manufacture components according to drawings, samples, or as individual developments. In any case, each solution is precisely tailored to your production and permanently increases its efficiency.

  • All production phases are integrated into a structured testing system that detects and documents deviations at an early stage. For particularly demanding applications, we test components individually according to your specifications.

  • 60 years of welding technology experience go into every product and every consultation. Our in-depth understanding of complex welding processes ensures stable production processes and reliable results.
