Welding Videos and Training

Learning how to weld, and learning a specialty, is the key to a great career and the potential to earn a lot of money. For beginners, the easiest welding process to learn are what is known as arc welding or gas welding, to include mig and tig welding.

Arc welding uses a power source to generate an electric arc between an electrode (either consumable or non-consumable) and the base material in order to melt the metals being welded. The area being welded is shielded by an inert or semi-inert gas. Because of it's low cost and efficiency, arc welding has become very widely used.

MIG, or Metal Inert Gas, and TIG, for Gas Tungsten Arc, are types of welding known as gas metal arc welding. When using either of these processes, the welding gun is continuously fed consumable wire electrodes along with a sheilding gas. Gas metal arc welding was first utilized for welding aluminum, but its usage soon spread to steel, as these techniques significantly lowers the time it takes to weld a given project.

Their are several advantages to MIG welding. First, it is easier to learn. Second, longer welds can be made. Third, little post-weld cleaning is needed. The downsides include oxidized weld deposits, an arc than can be unstable, and a porous weld.

TIG welding also holds several advantages. TIG welding produces welds of high quality, with or without the usages of filling metals. Heat is easily controlled, and distortion is low. The downside of TIG welding include a high consumption of electrodes, a wandering arc, and a porous weld.
