Evolution of Welding
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.

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.

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

    Welders have to do many tasks with metal working every day. The main job of a welder is to join metal parts and to fix broken metals. This is done with an electric tool that uses extreme heat to melt metal wire as it is applied to the metal. I think working with heat in high temperatures could be a problem. Also, welding is a job that can only be done on metal material. If metal breaks it can be fixed while most other materials with most likely be easily replaced. This could make the job easier for me by only using certain metal materials. Overall, the job of a welder could be very easy or very difficult.…

    Jim MacDonald founded AWC Inc. in 1950. He nurtured it to become a successful organization with a great company culture and eventually passed it down to his son, Alex. It seemed as though AWC was well on its way. Unfortunately, a recession came about, financially crippling AWC and the aluminum fabrication industry. To uphold the firm’s competitive advantage, AWC created a new door design - one that was competitive in price, assembly, and performance. It significantly increased sales and was in high demand. It was functional even in high-use areas, provided that the door spent more time on the welding line for a stronger welded corner. This change proposed a problem. The welding line produces poisonous fumes. When inhaled, they can have dire consequences on employee health as they have been known to lead to respiratory damage and cancer.…

    Metal Inert Gas (MIG) welding, also sometimes called Gas Metal Arc Welding (GMAW) is a process that was developed in the 1940s for welding aluminum and other non-ferrous metals. MIG welding is an automatic or semi-automatic process in which a wire connected to a source of direct current acts as an electrode to join two pieces of metal as it is continuously passed through a welding gun. A flow of an inert gas, originally argon, is also passed through the welding gun at the same time as the wire electrode. This inert gas acts as a shield, keeping airborne contaminants away from the weld zone.…
