  • Apparatus for cathodic protection in an environment in which thin film corrosive fluids are formed and method thereof
    Patent number: 7198707
    Abstract: An apparatus and method for cathodic protection in an environment where thin film corrosive fluids are formed is provided. The apparatus which protects from corrosion an object exposed to the thin film corrosive fluids, by artificially adjusting a potential of the object, comprises a DC power supply of which cathode is electrically connected to the object to be corrosion-protected, and an anodic assembly of which anode is electrically connected to the DC power supply.
    Type: Grant
    Filed: February 12, 2003
    Date of Patent: April 3, 2007
    Assignee: Korea Power Engineering Co. Inc.
    Inventors: Hyun Young Chang, Gon Hwangbo, Tae Eun Jin, Min Yu Shin
  • Local heatsink welding device and welding method thereof
    Patent number: 7091447
    Abstract: Provided is a local heatsink welding device and a method of welding using the same. The local heatsink welding device includes a welding torch disposed above welds of two pieces of a base metal placed in contact with each other to be welded, the welding torch welding the pieces of the base metal by melting a welding wire on the welds of the base material and fusing the pieces together; and a cooling unit disposed to be able to spray a low-temperature fluid from the sides of the welding torch, the cooling unit cooling at least a portion of a heat-affected zone formed around the outside of a fusion zone in which the base material is molten during welding.
