Welder World has just released a new section of their website that has Underwater Welding and basic Underwater Welding tips defined and everything else on Underwater Welding. This is part of a new community website that is all about the Underwater Welding Basic Information. Members and non-members can visit this Underwater Welding Tips and Basics page on the Welder World website for free at: http://www.welderworld.com/
Here is an excerpt from the new Underwater Welding Tips and Basics webpage:
“Underwater welding is done under water in the ocean and is used when there is a need to repair a ship, oil platforms that are offshore and pipelines. Usually these all need to be repaired using steel only. There are two basic types of underwater welding and these will depend on whether the situation needs a dry welding or a wet welding. These are called hyperbaric welding.
Both of these occur underwater but the dry aspect is done through a special pressure chamber that creates the dry environment. This dry mode can be better controlled underwater. This is used when there is a need for very deep water welds and where a high degree of strength is required. Research is being conducted to see whether dry welding can be done at depths of 1000 meters.
When dry welding is used, the chamber is filled with a gas mixture has to be used to seal the structure that is being welded. Usually a gas tungsten arc welding is used to make sure that this is a strong weld. For those structures that receive wet underwater welding it is difficult to know whether the weld has worked because the risk that may be involved are difficult to see in the water.”
