Underwater welders are skilled professionals who perform welding tasks beneath the surface of water. They use specialized equipment to join metal parts, often for construction, repair, or maintenance of structures like bridges, ships, and pipelines. This work requires both welding expertise and diving skills, as they operate in challenging underwater environments. The process of underwater welding can be done using two main techniques: wet welding and dry welding. Wet welding involves using electric arc welding techniques directly in the water, while dry welding takes place in a controlled environment, such as a hyperbaric chamber. Both methods require safety precautions due to the risks associated with working underwater.
