Effect of pipe welding

Welding is a welder parts material (homogeneous or heterogeneous), and by heat or pressure or both, and with or without filler material, the material of the workpiece between the atoms under construction and form a permanent connection process of mild steel pipe.

Welding process, the workpiece and the solder melted to form a molten region, bath cooling and solidification after the formation of the connection between the materials. This process, usually also need to apply pressure. Source of energy there are many, including a gas flame, electric arc, laser, electron beam, friction and ultrasonic welding. Before the end of the 19th century, the only welding process is a blacksmith in use for hundreds of years of metal forging welding. The earliest modern welding technology in the late 19th century, the first arc and oxygen gas welding, and later appeared in resistance welding. Early 20th century, with the first and the Second World War, the war, demand for military equipment is cheap and reliable connection method greatly, it is to promote the development of welding technology. Today, with the welding robot widely used in industrial applications, researchers are still in-depth study of the nature of welding, to continue to develop new welding methods to further improve the welding quality of carbon steel pipe.
