Also called hyperbaric welding, underwater welding was invented in the early 1930s and is still used for maintaining and repairing fully or partially submerged marine structures. Inland hyperbaric welders can work on small seacraft, dams and bridges. On the other hand, offshore welders have to work on ships, oil rigs, pipelines and underwater habitats. They may even have to perform welding work on nuclear power facilities. #selam #diver #pengelasan #Underwaterwelding #trend
