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

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

WELDING OF CAST IRON Cast iron is an extremely versatile material‚ used in thousands of industrial products. It is hard‚ wearresistant‚ and relatively inexpensive. Like steel‚ it is available in many different grades and compositions. While we usually think of cast iron as being brittle (having low ductility)‚ this is not true of all cast irons‚ as we shall see shortly. Cast iron‚ like steel‚ is an iron-carbon alloy. In composition and structure‚ and in some of its properties‚ it is quite different

We are constantly hearing through television and other media sources that the job market for people trained in some sort of vocational skill is in very high demand. Media advertisements are encouraging students to consider a vocational skill when looking at their future. Welding is one

The dictionary defines electric arc welding as “A technique in which metals are welded using heat generated by an electric arc.” It is a type of welding that uses a welding power supply to create and electric arc between an electrode (the dictionary defines electrode as “A conductor through which electricity enters or leaves an object‚ substance‚ or region.”) and the base material to melt

term‚ which covers processes such as welding‚ brazing‚ soldering‚ adhesive bonding‚ and mechanical joining. These processes are an important and necessary aspect of manufacturing operations. This paper deals with one topic in particular ‘Welding’. Welding is a process for joining similar metals. Welding joins metals by melting and fusing the base metals being joined and the filler metal applied. Welding employs pinpointed‚ localized heat input. Most welding involves ferrous-based metals such as

essay The three types of welding are Mig‚ Tig‚ and Stick. All three of these welding styles have special purposes and are widely used in the world. Mig or Metal Inert Gas welding is the most common type of welding. Tig‚ or Tungsten Inert Gas‚ welding is the hardest method to learn‚ but it has the most satisfying finish welds. Stick or Shielded Metal Arc welding can be done under water‚ to repair large channel boats that aren’t able to be lifted out of the water. Mig welding uses a supply of argon
