Underwater welding has always fascinated me, especially when I heard about it during my time as a welding student at Arizona Automotive Institute (AAI). The history behind it has always grasped my attention for some time now. I always wanted to know more about underwater welding such as the history, how it works, what it is used for, and the dangers that are associated with the job. Konstantin Khrenov was a Soviet Engineer, who would later make history by inventing underwater welding. Khrenov was born in 1894 in Borovsk, Russia. He got his education at Saint Petersburg State Electrotechnical University (ETU), where he learned about electric welding, engineering, and mathematics. He had also taught and did research at ETU until 1925. Underwater welding was not a thing people attempted during the 20th century, because shooting an electric arc into the water was considered suicide. Although, Khrenov had a desire to find a way to weld underwater, but faced many challenges such as, trying to find the sporadic outflow of gas bubbles which would cause major porosity or build up in the welds. During this time, he and others did research and testing to create a waterproof coating for the electrodes for stable power. Once he completed this, he tested out the electrodes. After constant testing and practice he became successful at creating underwater welding in 1932. Many people were enthused about the idea that two scientists wrote two articles about his accomplishments. The Navy
