Metal arc welding process
Introduction to metal arc welding process Metal arc welding process is a method of welding that is done manually it is also called as stick welding. In this type of welding an electric arc is produced from the electrode that is used to weld the base metal; Therefore the name metal arc welding.
The process uses an electrode that is coated heavily with a protective coating. This electrode is made of the consumable metal; this metal melts in the process of welding to weld the two pieces of base metals. When voltage is applied and electricity is passed through the electrode, the metal melts and sticks to the base metal, the heavy coating that is applied to the electrode disintegrates and forms vapor. This vapor formation is due to the heat generated by the electrode due to the passing of electricity. The vapors form a flux of slag and cover the melted metal thus pressurizing it to stick to the base metals, that need to be welded, properly and they also prevent oxidation of the melted metal. The electricity that is passed through the electrode causes electric arcs between the base metal and the electrode.
Advantages of metal arc welding process
Metal arc welding is a simple and efficient process. The end result in most cases is as desired. The process is inexpensive as well. This process can be used at different scales for different types and different sizes of welding. This is the most popular method of welding in the world. This process has applications in construction industry, steel industry, metal structure construction, and maintenance and repair industries. This method is most suitable for iron, steel and stainless steel. However with minor modifications it can be used for welding aluminum, copper alloys and nickel.
Conclusion for metal arc welding process
Metal arc welding is the process of welding two pieces of metals using an electrode through which electricity which is either alternating current or direct current is passed. This current causes an arc between the electrode and base metal. The electrode melts and gets deposited between the two metal pieces to be welded and binds them.
