Developed exclusively by SILICON, Rapid Arc Welding (RAW) is an innovative method of fixing refractory anchors inside high temperature vessels and furnaces

It is recognized industry-wide for its ability to optimize the quality, speed and safety of the anchor installation process.

Using RAW technology rather than conventional stud welding, our teams can dramatically reduce the installation time while achieving unparalleled precision

When it comes to installation, our mobile Rapid Arc Welding teams are ready to respond to the challenge, wherever it may be in the world.
Or, if you prefer to weld the anchors yourself, you can rent or lease RAW equipment and technology
so that your own workforce can carry out the installation. We will train your team of course to garantee the best results.

The key benefits of the use of SILICON Rapid arc welding (RAW) vs Handwelding are obvious : no poisonous fumes, no electrodes & no welding protection needed, less operators & much higher speed of production, consistent high quality, easy to learn.

Some customers had such a bad experience with the "conventional" Stud Welding technology that it drove them away from any "welding gun". Read below why our "computer-controlled" RAW equipment is so UNIQUE.

CEMEX Project

Jorg Spzerlinski - Manager Engineering & Projects Cemex Germany : "The big advantages of this system are the high speed of installation and that the studs will hold for a long period of time. When the anchors have worn down, you can still use the SpeedBolts so that you only need to replace the anchors."
