HAMMERHEAD WET-SPOT WELDING ELECTRODES

Ordering Codes: 3.2mm – WELD0017/3.2 – 4.0mm – WELD0017/4.0

The Hammerhead™ welding electrode is a specially designed and formulated ‘wet-spot’ electrode for spot/plug welding of steels, which can be used both above and underwater. This permits a real alternative to conventional wet welding, which required high levels of skill to produce high quality welds. Using the Hammerhead process quality welds can be produced without the need for any conventional welding skills, as all that is required to produce a weld is for the diver to press the electrode onto the surface of the material, where it will then pierce through the plates to be joined forming a spot/plug weld.
