Types of Welding Series - Arc Welding
There are over 100 different types of welding. This post describes the most common.
Arc welding is a popular form of welding due the low cost of the process. The process begins with a device that gives off an electric current. This device can differ greatly from process to process yet it always enables electric current to move through materials that without the device, would be considered non-conductive. It is called ‘arc welding’ because an electrical current is created between the welding device and the materials to be welded which at times gives an arch like appearance. The first basic form of arc welding was invented in the year 1802. Today, many other subcategories of arc welding exist.
Gas Metal Arc Welding
The process of Gas Metal Arc Welding (GMAW), created in the 1940’s, is another automatic welding process. This method consists of the use of a welding gun which automatically feeds the weld metal through the gun for use. The weld gun also automatically distributes a protective gas as a shield from the natural elements. This process saves a lot of time and is best for a large quantity of welding work. It was originally developed for use with aluminum metals. Today, this method is mostly used by those welders in the automobile repair and manufacturing industries.
