Application of welding technology of rail welding machine in chemical machinery manufacturing

Welding rail welding is a science and technology rising early in the twentieth Century. It has been widely used in aviation, aerospace, atomic energy, chemical industry, shipbuilding, marine engineering, electronic technology, architecture, transportation, electric power, machinery manufacturing and other industrial sectors.
According to the characteristics of welding process, metal welding can be divided into two categories: fusion welding and pressure welding. Each type can be subdivided into many methods, as shown in table 1-1..
Most of the typical machines, containers and equipment in the chemical machinery of the rail welding machine are welding structures, and welding is the key process in the manufacturing of chemical machinery. It directly affects the quality, productivity and cost of the products. In the manufacturing process of chemical machinery, especially the manufacture of pressure vessels, the welding method is mainly by melting and welding, and the manual electricity is used. Arc welding, submerged arc welding, electroslag welding, gas shielded arc welding, plasma welding, especially the current methods of pressure vessel welding. The application of electron beam welding and laser welding in chemical machinery manufacturing is still in the stage of research and trial. The principles and uses of commonly used welding methods for pressure vessels are also studied.
The welding technology of rail welding machine can be widely applied in chemical machinery manufacturing, mainly because it has many characteristics different from other manufacturing processes. Compared with the structure of riveting, casting and forging.
