introduction：Welding in water。This kind of welding was originally applied to salvage at sea and emergency repair of ship below the waterline。20century60After ten years，Due to offshore oil extraction，Undersea oil depots are needed、Laying of oil pipelines，Assembly of production platforms, etc，Underwater welding technology has been developed（See color diagram[Underwater welding]）。Underwater welding can be divided into wet welding、Dry welding and partial dry welding3class。 Wet welding welding is performed directly in water。Mainly by manual arc welding。Waterproof coating is applied to the outer surface of underwater welding electrode，A large amount of gas is released during the melting process,Drain the water around the welding arc,

introduction：Laser welding and arc welding are two commonly used methods for mold repair。 Argon arc welding Argon arc welding is a kind of arc welding，The burning arc between the continuously fed welding wire and the workpiece is used as the heat source，It is welded by the gas emitted from the torch nozzle to protect the arc。At present, argon arc welding is a common method，Suitable for most major metals，Carbon steel included、Alloy steel。Mig welding is suitable for stainless steel、aluminum、magnesium、copper、titanium、Zirconium and nickel alloys，Due to low price，It is widely used in mold repair welding，But the welding heat affected area is large、Defects such as large solder joints，At present, the laser has been gradually supplemented in the repair of precision molds
