underwater welding is a type of welding which takes place underwater in underwater welding the environment around the welder is wet and uses welding equipment which has been customized for wet environment commonly use under water techniques are hyperbaric enclosure welding wet underwater welding high pressure water jet welding

ultrasonic welding usw is a welding technique that uses ultrasonic vibration of high frequency to weld the two pieces together it is most commonly used to weld thermoplastic materials and dissimilar materials metal with a thin section can also be welded with usw

oxy fuel welding commonly called oxyacetylene welding oxy welding or gas welding in the u s and oxy fuel cutting are processes that use fuel gases or liquid fuels such as gasoline and oxygen to weld or cut metals french engineers edmond fouché and charles picard became the first to develop oxygen acetylene welding in 1903

the weld formed in gas metal arc welding is free from slag it is a clean and efficient process this is the working of the gmaw or mig welding process advantages it is faster welding process it has greater deposition rates it provides better weld pool visibility after the welding process is over it requires less cleaning

the underwater welding is also called hyperbaric welding it is the process of welding at high pressure in underwater there are two types of weldings performed on underwater wet welding and dry welding

fig 1 systematic diagrams of dry and wet welding process iii wet welding wet welding indicates that welding is performed underwater directly exposed to the wet environment a special electrode is used and welding is carried out manually just as one does in open air welding
