Underwater Contractor International 23 Speciality Welds’ new system, which has been named Hammerhead in keeping with the company’s ‘fish’ brand, addresses problems in obtaining high quality wet welds in nil visibility, without the need for experienced (skilled) welder-divers. By removing the individual welding skills from the operation, there’s no need for the diver-welder to control parameters that affect quality, such as travel speed, electrode angle, arc length and accurate deposition. Because the operator no longer needs to control these parameters, it is not essential to have good visibility. So, even in nil visibility conditions high quality repeatable welds can be produced
time after time. How the system works In removing the skills necessary to carry out underwater wet welding, Speciality has modified the fundamental approach to how ‘stick’ welding is carried out. The company’s system allows the operator a far more simplified role. How is all this achieved? In simple terms, by creating a spot/plug weld rather than
having to deposit a fillet weld within a specified joint. By removing the need for a
fillet weld deposit Speciality has also simplified the joint configuration (simple lap
joint) and all the preparation that goes with it, while also removing the need for extensive cleaning of the joint area and chipping off metres of slag prior to additional passes. In fact there is no need for additional passes as the process is designed as a ‘oneshot’
Approach, ie, one electrode produces one spot/plug weld. Other than the control system/electrodes, all other equipment is exactly as conventional ‘stick’ welding. The control unit is connected to the welding power source via the remote control facility and is powered by 110-volt supply.
