The welding experiment system is used for simulating the underwater welding.

Description

technical field [0001] The invention relates to an underwater welding system, in particular to a welding experiment system for simulating a medium-pressure liquid or gas environment. Background technique [0002] With the development of marine resources, a large number of steel structures are used in marine engineering, such as submarine oil pipelines, offshore drilling platforms, and sea-crossing bridges. Whether it is the construction of structures or the maintenance of facilities, underwater welding is required. Whether it is the construction of structures or the maintenance of facilities, underwater welding technology has irreplaceable advantages. Underwater wet welding can be applied to pressure environments where the water depth does not exceed 100 meters; when the water depth exceeds 100 meters, underwater high-pressure dry welding is generally used. Regardless of underwater wet or high-pressure dry welding, welding is carried out in an environment higher than 1 atm...
