Dry hyperbaric welding
Did you know?
Hyperbaric welding is the process of welding at elevated pressures, normally underwater. Hyperbaric welding can either take place wet in the water itself or dry inside a specially constructed positive pressure enclosure and hence a dry environment. It is predominantly referred to as "hyperbaric … See more Welding processes have become increasingly important in almost all manufacturing industries and for structural applications (metal skeletons of buildings). Of the many techniques for welding in atmosphere, most … See more Wet underwater welding directly exposes the diver and electrode to the water and surrounding elements. Divers usually use around 300–400 amps of direct current to power their electrode, and they weld using varied forms of arc welding. This practice commonly uses a … See more • Oxy-fuel welding and cutting – Metalworking technique using a gaseous fuel and oxygen See more Dry hyperbaric welding involves the weld being performed at raised pressure in a chamber filled with a gas mixture sealed around the structure being welded.
