What is an electrical welding?
Electroslag welding is a welding process outside the ARC using an electric current that passes between consumer electrodes and work. When this welding method is performed, the electric current is carried out by a liquefied slag that obscures the weld surface. Before starting welding of electroslags, the welding flow is used to fill the gap between the working pieces and to create the heat required to melt the flow and the formation of the slag is used an electric arc. During this type of welding, the slag remains in the molten state from the heat from the electric current.
Electroslag welding is most often used to connect dense steel plates together. This welding method is usually done by placing two water -cooled equipment to maintain copper on each side of the work pieces to create an emptiness for the molten flow. The filler wire used as an electrode is added to the emptiness along with a small amount of welding flow. An electric arc and an addinum are generated to start the melting processEye amount of flow is added until the melted slag is emptied and bears an arc. The filler wire melts into a liquefied slag and forms a weld as it solidifies; The process continues by moving the supporting equipment and filling wires up to the end of the weld.
Variations of the typical electroslage welding process are sometimes used to shorten working hours. In this variation, the welding process is performed in a typical way, except that the filling wire is fed to the molten pool using a consumer tube. This tube is located at the top of the weld and brings the wires to the molten flow in an oscillating way for wider joints. In this variation, two sets of copper of chilled copper are used so that they can be moved along the jump over the other. This variation is particularly useful when the welding process is performed.
Robert K Hopkins patented the electrical welding processGu in the US in 1940. This welding method was further refined at the Paton Institute in U.S.S.R. all over the 1940s. The refined method of the Paton Electroslag welding was first introduced at the Bruxelles trade fair in 1950 and began to be used by American car engines to produce engines in 1958.
