Hyperbaric welding is the process of extreme welding at elevated pressures, normally underwater. [1] [2] 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 welding" when used in a dry ...
Barotrauma is physical damage to body tissues caused by a difference in pressure between a gas space inside, or in contact with, the body and the surrounding gas or liquid. [ 76 ] [ 33 ] The initial damage is usually due to over-stretching the tissues in tension or shear , either directly by an expansion of the gas in the closed space or by ...
Oxygen arc cutting and arc welding underwater requires greater skill and stamina than working in a dry and stable environment. The underwater environment imposes several limitations and restrictions on both the equipment and the operator, and the restriction of short bottom times at greater depths for surface-oriented divers makes efficient working important to getting the job done in a ...

Depressurisation causes inert gases, which were dissolved under higher pressure, to come out of physical solution and form gas bubbles within the body. These bubbles produce the symptoms of decompression sickness. [6] [7] Bubbles may form whenever the body experiences a reduction in pressure, but not all bubbles result in DCS. [8]
