In every industry there are problems that are associated with the connection of metal parts: obtaining reliable metal, the connection of large diameter pipes connecting the various body parts car and many more other tasks that can be solved only welding. There are various methods of welding, such as Thermoplastic, electron beam, gas welding and Electrogas. The most common type of welding is Electrogas Automatic and semi-automatic arc welding, which is used in the manufacture of complex and important structures, using a special welding wire, which moves in an arc, and arc moves along the line of welding. Welding wire, usually wound on a framed Ryadno coil and wire as needed continuously fed into the arc. Welding wire is used for cladding and welding low alloy and carbon steels in various fields, including shipbuilding. What is the advantage of using a wire? First of all, it is reliable and accurate joints capable of withstanding high pressure, highly-continuous welding process, low material consumption and arc stability. Welding wire is selected depending on what task you need to decide whether welding of pipes bodies, tanks, welding of shipbuilding steel, for certain tasks require a certain type of wire.
According to the chemical content of carbon and alloying elements were divided into three groups of welding wire: 1. Mild welding wire 2. Alloy welding wire 3. High-alloy welding wire less carbon content in the welding wire, the more plastic than metal. Depending on the type of wire, It may contain various alloying elements such as manganese, silicon, nickel, chromium, titanium and others.
