Butt welding machines are widely used because of their high productivity and ease of automation. Its application range can be summarized as follows：
(1) The length of the workpiece, such as the butt welding of strip steel, profiles, wire rods, steel bars, rails, boiler steel pipes, oil and gas transmission pipes, etc.
(2) Butt welding of annular workpieces, such as butt welding of automobile rims, bicycles, motorcycle rims, butt welding of various chain rings, etc.
(3) Assembly welding of components: Butt-weld simple rolled, forged, stamped or machined parts into complex parts to reduce costs. For example, the butt welding of the car steering shaft shell and the rear axle shell, the butt welding of various connecting rods and tie rods, and the butt welding of special parts, etc.
(4) Butt welding of dissimilar metals can save precious metals and improve product performance. For example, the butt welding of the working part (high-speed steel) and the tail (medium carbon steel) of the tool, the butt welding of the head (heat-resistant steel) and the tail (structural steel) of the exhaust valve of the internal combustion engine, the butt welding of aluminum-copper conductive joints, etc. .
