Electro gas welding
The electro gas welding is a continuous welding process. In this process the arc is struck between the work piece and the electrode used. The arc is struck by keeping the electrode in a vertical position over the work piece. The arc that is used in this process is not extinguished like in electro slag welding. It is used throughout the welding process. With the help of this process we can make square groove welds on butt joints and t joints. This is especially useful in the shipbuilding industry. Also in the construction of storage tanks such a process is used. For a electro gas welding process, you need to have a constant voltage direct current welding power supply. This can be purchased from manufactures of welding products. If you have difficulty in locating such a supplier then you can always get in touch with such people with a simple search of the internet.
