Welding? Yes, welding have you ever wonder how it has been revolutionised throughout the years. The man who created welding was Edmund Davy with the help of Sir. Humphry Davy in the late 1800’s. As the years go on the technique of weld was further advanced.
With the evolution of welding many of the ways created back in the start have been adjusted and also have been modified for the use for the everyday welder. Welding is a very difficult and hard working job that can take a toll on your body over the years and all the welding are very dangerous but the first form was the art of arc welding.
Arc welding is combining pieces of metal together using the electrical currents being concentrated at the end of a stick also known …show more content…
http://waterwelders.com/underwater-welding-history/ Khrenov was a former student at the (ETU) aka Saint Petersburg State Electrotechnical University. As his years at the university continued he always wondered how how he or anyone could be able to fix vessels. At the end of WWII Khrenov had discovered that if you put the right technology together you can have a welder that can be used underwater in order to fix many boats and any other vessels that can be taken out of the water in order to fix them by welding. As Khernov passed away another man decided to take his spot and further advance his invention. The man that took that role was a taking Khernov’s idea and pushing it to the limits of the test. The man was named Cyril Jensen Who has helped the navy in repairing their boats without being detected by the noise of an original welder. One thing that the inventors did not think of is the lifespan of a underwater weld is cut in half or more because of the gas and other things that are floating in the water and if any of that touches the arc by the welder it causes an explosion that kills everyone that is touching the water that isn't in the boat. Yes this is the most dangerous type of welding that is known to mankind and that anyone that is a welder for this has there life cut in almost half because of the conditions and many things that could happen to them even though it has it flaws it can be a very successful job. http://waterwelders.com/underwater-welder-life-expectancy/
Many of these types of welding has had it's ups and downs but they all have something very in common and that yes some of these can be a life threatening thing and also some of them have been a very successful improvement to the everyday world we are living in
