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.
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
The ability to perform complex welding tasks in challenging underwater environments has made this technology indispensable to industries operating offshore or near large bodies of water. Hyperbaric welding encompasses both dry (performed inside a specially created underwater chamber) and wet welding (performed directly in the water).
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 ...
