Welding is a method for the permanent assembly of metal parts. Arc welding can be divided at least three classes: arc welding‚ gas welding‚ and resistance welding. 1) Arc welding: Heat is generated by an electric arc and the parts are simply fused together and became one. In some cases electrode is used that provides a filler material. 2) Gas welding: The burning gas (oxygen and acetylene) raises the temperature of the part to be joined and a welding rod provides filler material. 3) Resistance

Underwater welding‚ Underwater welding was invented in Russia in 1932 by Konstantin Konstanovich Khrenov and used it throughout the soviet navy. During WWII‚ the American Cyril D. Jensen‚ professor of engineering at Lehigh university‚ developed the USA’s own underwater welding programs and created 2 U.S. patents in the field. (Agnew‚ 1999-2013) Under water is a technique that is employed in various engineering projects‚ where in welding is carried out under the surface of the water. Underwater

Metal Welding - Types and Processes Welding. So you think it’s as simple as grabbing the gun and pulling the trigger‚ eh? Tell me this then - what types of welding are there? Not completely sure? Read on... Arc Welding Arc welding is a process utilizing the concentrated heat of an electric arc to join metal by fusion of the parent metal and the addition of metal to joint usually provided by a consumable electrode. Either direct or alternating current may be used for the arc‚ depending upon

"Welding With Children" Language Analysis "He just stared at me‚ and i saw that he had no idea of what late was. Glendine‚ his mama‚ probably lets him fall asleep in front of the set every night. I pictured him crumpled up on that smelly shag rug she keeps in front of the TV to catch the spills and crumbs" (2). Within the passage it mentions that the child had no idea what late was.

The hydropolis underwater hotel and resort is a proposed underwater hotel in Dubai . The hotel’s original plan was to be located 20 meters under water off the coast of Jumeriah Beach. The hotes plan is to cover an area of 260 hectares which is equivalent in area to Hyde Park in London . The construction cost of Hydropolis is approximately $550 million US dollars ‚ which will make Hydropolis one of the most expensive hotels ever created . The hotel design was created by Joachim Hauset and Proffessor

There are lots job aids such like jigs‚ and pipe holders available to help welders do their job and minimize the risk of injury. Special chairs and creepers are available to provide support while performing welding tasks so that bad posture is avoided. There are many causes of injury in the welding field. Common causes of injury are repetitive gripping‚ twisting‚ repetitive reaching‚ and fatigue. Many injuries are developed when there is a mismatch between the capabilities of the worker and the demands
