Underwater Welding

No one likes working underwater. Let’s take a look at some of the ways the work is done, and the risks that come with that type of work.

How Does Underwater Welding Work?

Few are aware of underwater welding. This welding process comes as a surprise to many as electricity and water appear to be a hazardous and incompatible combination. However, underwater welding is a lucrative field and one of the most well-paid occupations for commercial divers.

How Is Underwater Welding Done?

Diver-welders have a range of options at their disposal to carry out the welding task. Depending on the task provided, skilled underwater welders and project managers should discuss the most appropriate welding process to fulfill requirements.

How Dangerous Is Underwater Welding?

)Of course, as expected, underwater welding is an incredibly dangerous field of work. Though many water flow hazards impede diving operations, some of the largest dangers to underwater welders may be surprising.

Underwater Welding Information

Underwater welding is performed while the welder is submerged, often at elevated barometric pressures. This introduces a variety of challenges that require specialized skills and training that are taught at CDA Technical Institute (formerly Commercial Diving Academy). Because of the adverse conditions and inherent dangers associated with underwater welding (also known as wet welding) divers must be trained to an exceptionally rigorous standard with highly specialized instruction.

Although a large number of techniques are available for welding in atmosphere, many of these techniques cannot be applied in offshore and marine application where presence of water is of major concern. In this regard, it is relevant to note that a great majority of offshore repairing and surfacing work is carried out at a relatively shallow depth, in the region intermittently covered by the water known as the splash zone. Though numerically, most ship repair and welding jobs are carried out at a shallow depth, the most technologically challenging task is repair at greater depths, especially in pipelines and repair of accidental failure. The advantages of underwater welding are largely of an economic nature, because underwater-welding for marine maintenance and repair jobs bypasses the need to pull the structure out of the sea and saves valuable time and dry docking costs. It is also an important technique for emergency repairs which allow the damaged structure to be safely transported to dry facilities for permanent repair or scrapping. Underwater welding is applied in both inland and offshore environments, though seasonal weather inhibits offshore underwater welding during winter. In either location, surface supplied air is the most common diving method for underwater welders. (Source: en.wikipedia.org)
