A new welding system, Hammerhead, by UK-based Speciality Welds, for obtaining high quality wet welds without the need for experienced, trained, and qualified welder-divers, is discussed. The new system comprises a standard three-phase DC welding power source and a Piranha II control unit for its wet spot-welding process. The system is usable even in poor visibility conditions, and produces repeatable quality. The system does not require any specific joint configurations and cleaning the joint area or chipping off slag, and a single electrode at the center of the design produces one complete spot/plug weld.
