  • Essay On Arc Welding

    681 Words  | 2 Pages

    INTRODUCTION Arc welding is a type of welding that uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point i.e. in arc welding the intense heat needed to melt the metal is produced by an electric arc. They can either use direct current or alternating current, and consumable or non-consumable electrode[1]. The arc is formed between the actual work piece and an electrode (stick or wire) that is manually or mechanically

  • The Process of Gas Metal Arc Welding

    834 Words  | 2 Pages

    Gas metal arc welding, or most commonly referred to as MIG welding is a very common and sometimes preferred method of welding. Gas metal arc is personally one of the easiest and controllable welding types there is. Gas metal arc welding was originally made for weld materials such as aluminum, copper, brass, tin and lead. It was also used on steels, but shielding gases were highly expensive in the early 1900s limiting GMAW’s use on steel. It wasn’t till the mid 1900’s for GMAW to really take off

    metal production. Welding has been incorporated into the framework of metalworking. Welding dates back to the middle ages where forge welding processes were used to make tools and weapons, commonly known as blacksmiths. It is known that the Egyptians used forms of welding to make gold tools, jewelry, and decoration. During the 1800’s a new process was formed by using carbon electrodes to form an arc. This was done by Sir Humphrey Davy, which carried on to become Carbon Arc Welding and the most used

    2.1 The Continuous Casting The Continuous Casting is a highly efficient manufacturing process, whereby molten metal is solidified into long, semi-finished shapes with constant cross section for subsequent processing in the finishing mills. Every year around 1 billion tons of steel, 20 million tons of aluminium and over 1 million tons of nickel, copper and other metals are produced all over the world in this manner. Continuous casting is distinguished from other solidification processes by its “steady

    basics joint in welding. Mild steel electrodes (MS 6013) of diameter 2.6 mm were provided to be used to join the two pieces of metal. For the diameter, the minimum amperage needed is 60A and the maximum it can retain is 100A. For the welding to be successful, an arc gap of 2 mm must be maintained throughout the operation. Also, the travel speed of the electrode must be slow in order to produce a uniform weld and the current must be kept constant in order to produce a stable arc. The welding power supply

    the three basic welding methods. How could they improve their career? The three basic welding methods are TIG(Tungsten Inert Gas.) MIG(Metal Inert Gas.) And SMAW(Shielded Metal Arc Welding.) If the welder had more knowledge about the welding methods, then they could figure out which of the three can produce the most welds in a certain amount of time. TIG welding is the optimum, and most efficient because it can deliver more welds in a day, and reduces the cost of sales. The welding trade has new TIG
