A Definition of Welding Welding is a joining process that produces a local coalescence of materials by heating‚ by applying pressure‚ or both. In essence‚ the welding process fuses the surfaces of two distinct elements to form a single unit. It encompasses a broad range of joining techniques that include fusion welding‚ solid state welding‚ weldbonding‚ diffusion welding‚ brazing‚ and soldering. The Scope and Impact of Welding Welding dates back to the earliest days of metalworking‚ and continues

Being a welder is a great occupation What is welding‚ and how does it work? Not many people know what welding is or how it works. According to Mary Bonk“welding is the process of heating and melting metal parts to join them together” (Bonk‚3). A welding machine uses electricity to melt the electrode‚ fusing one piece of metal to another. The welding machine uses a ground that connects to the surface that allows the welder to create a flowing currant passing through the electrode and

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. 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

Welding Dangers Annotated Bibliography "Warning: Welding May Be Hazardous to Your Health." Warning: Welding May Be Hazardous to Your Health. N.p.‚ n.d. Web. 12 Feb. 2013. This article explains a little about welding fumes and how they are dangerous to people’s health. There are short term and long term respiratory effects from welding gases and fumes. Some of the gases that are inhaled can cause diseases such as ones close to Parkinson’s disease. To be protected from these fumes‚ the work area

For the assessment of risk In order to work safely in a welding environment‚ it is necessary to be able to identify hazards and assess risks. To do that‚ one needs information‚ education‚ training and experience in the appropriate field of work. Legislation Employers have a duty to provide information‚ instruction‚ training and supervision to ensure health and safety at work. Employees have a duty to take care of their own health and safety and those of others‚ and must not intentionally or recklessly

harbour collided‚ creating the largest explosion until the detonation of the atomic bomb. The explosion killed many people and devastated Halifax‚ its harbour and the neighbouring towns of Richmond and Darmouth. The towns surrounding the harbour were thriving thanks to the war overseas and their populations grew drastically. Halifax quickly became a "boom" town by 1917‚ only three years after the war. Halifax’s population was about 50‚ 000 before the explosion‚ which at the time was one of the largest

“I Survived the Halifax Explosion” HALIFAX- The collision of two ships in Halifax Harbor caused a big explosion. The ship (Mont-Blanc) was filled with explosives‚ on deck and below. It was filled with highly explosive picric acid; gun cotton in the center; and in the aft hold‚ trinitrotoluene (TNT). The explosion occurred when the Imo vessel was leaving Halifax Harbor and on its way to New York. Suddenly‚ the French munitions ship Mont Blanc was on its way to wait for a convoy when the two

previous 50 years‚ welding has become more productive‚ automated‚ and safer. Generally‚ the welding norm was resistance based and performed with big machinery. The aerospace industry spurred the innovation of new ways to weld thin metal. At this point in history‚ all welding systems had good and bad aspects; the choice should be made with a balance between the different capabilities of the systems‚ including its power requirements and limitations. Manufacturers used this welding technology to hold

TIG welding T ungsten inert gas (TIG) welding is a high quality low deposition rate welding process. It uses an arc struck between a nonconsumable tungsten electrode and the work to fuse the base material and thereby form a welded joint. The TIG welding process may be used on thin sheet material without the addition of a filler metal (autogenous TIG welding). Alternatively‚ when working on thicker sheet or when joining dissimilar materials‚ a separate wire filler metal is added
