Man welding a metal structure in a newly constructed house in Bengaluru, India Arc welding is a process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals when cool result in a binding of the metals. It is a type of that uses a to create an between an electrode and the base material to melt the metals at the welding point. They can use either (DC) or (AC) current, and consumable or non-consumable. The welding region is usually protected by some type of, vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated. Bmw Road Map Europe Professional 2014 here.

First developed in the late part of the 19th century, arc welding became commercially important in shipbuilding during the Second World War. Today it remains an important process for the fabrication of steel structures and vehicles. A diesel powered welding generator (the electric generator is on the left) as used in. To supply the electrical energy necessary for arc welding processes, a number of different power supplies can be used. The most common classification is constant power supplies and constant power supplies. Crack And Serial Key more.

In arc welding, the voltage is directly related to the length of the arc, and the current is related to the amount of heat input. Constant current power supplies are most often used for manual welding processes such as gas tungsten arc welding and shielded metal arc welding, because they maintain a relatively constant current even as the voltage varies. This is important because in manual welding, it can be difficult to hold the electrode perfectly steady, and as a result, the arc length and thus voltage tend to fluctuate. Constant voltage power supplies hold the voltage constant and vary the current, and as a result, are most often used for automated welding processes such as gas metal arc welding, flux cored arc welding, and submerged arc welding. In these processes, arc length is kept constant, since any fluctuation in the distance between the wire and the base material is quickly rectified by a large change in current. For example, if the wire and the base material get too close, the current will rapidly increase, which in turn causes the heat to increase and the tip of the wire to melt, returning it to its original separation distance. The direction of current used in arc welding also plays an important role in welding.
