Butt welding application range of large diameter elbow manufacturers


Butt welding is divided into resistance butt welding and flash butt welding. Large diameter butt welding elbow is a kind of resistance welding method that uses resistance heat to weld two workpieces simultaneously along the entire end face. Butt welding is widely used because of its high productivity and easy automation.
The application range of large diameter elbow can be summarized as follows:
(1) Butt welding of ring-shaped workpieces such as butt welding of automobile rims and bicycle and motorcycle rims, butt welding of various chain rings, etc.
(2) the length of the workpiece such as strip steel, profiles, wire, steel, steel rail, boiler steel pipe, oil and natural gas pipeline butt welding.
(3) The assembly welding of components will be simple rolled, forged, stamped or machined parts welded into complex parts to reduce costs. For example, butt welding of automobile direction shaft housing and rear axle housing, butt welding of various connecting rods and tie rods, and butt welding of special parts.
(4) Butt welding of dissimilar metals can save precious metals and improve product performance. For example, the butt welding of the working part of the tool (high-speed steel) and the tail (medium carbon steel), the butt welding of the head (heat-resistant steel) and the tail (structural steel) of the exhaust valve of the internal combustion engine, and the butt welding of the aluminum copper conductive joint.
