UW Welding / Cutting

This is a physically demanding industry and, as a commercial diver, requires that a person pass a physical examination each year in order to maintain their commercial dive license.

It is also important that a person be extremely safety conscious when training or working underwater.

Because of the hours spent under water, it is also important that the welder have no fear of working in enclosed spaces.


In addition, and this should go without saying, but if you partake in heavy drinking or use drugs of any type, this is not for you. When things go wrong in the water, the go wrong fast. So you need every advantage you can muster which includes physical and mental strength.

Occupational Diving

Standards around the world maybe local or federal (UK HSE), (ADAS) etc. 

And there are organisations representing the Industry like IMCA and IADC / ADC.
