  3. 3. INTRODUCTION Welding is one of the unavoidable process of modern engineering. Under water welding provides a means to a assemble or repair underwater.
  4. 4. ORIGIN First Under Water Welding was invented by Russian metallurgist Konstaintin Khrenov in 1930. Special water proof electrodes were developed in Holland by Van Der Willingen in 1946. First under water welding was applied by British Admiralty in Dock Yard.
  5. 5. TYPES OF UNDER WATER WELDING Dry Welding. In this process it is seal by closed chamber filled with gas at elevated pressure. Wet Welding. In this process it is directly exposed to the environment. And a special water proof electrode is used.
  6. 6. ADVANTAGES OF UNDER WATER WELDINGs A. Dry Welding. i. Driver Safety ii. Good Quality Weld iii. Surface Monitoring iv. Non Destructive Testing Possible. B. Wet Welding. i. More versatile and low cost. ii. Easily reachable any portion of area. iii. High Operating Speed iv. Minimal amounts of equipment is needed.
  7. 7. SAFETY CONCERN
  8. 8. APPLICATIONS
  9. 9. Application  1. Offshore  2. Construction  3. Ship and Submarine  4. Pipe Lines and Tunnels  5 Salvaging Vessel sunk inside water  6. Oil Refineries.
  10. 10. FUTURE SCOPE  Automation of the underwater joining and inspection.  2. Mechanized underwater welding for actual usage of a very large floating surface.  3. Investigation by using a robot manipulator for underwater ultrasonic testing for complex geometry.  4. Application of advanced welding technique, like friction, laser welding.  5. Invention of new welding techniques and explore the possibility.
