Butt welding connection is one of the commonly used connection methods in the engineering field, and one important type is “butt welding” or “fusion welding”.
Butt welding is a common metal connection technique, especially suitable for the connection of identical or similar metal materials. One of the most commonly used types in butt welding is “butt welding”, also known as “button welding”.
Butt welding is a welding method that aligns and connects the ends of two metal workpieces to each other. This connection method is usually used for manufacturing pipes and flanges. For example, welding neck flanges, slip on hubbed flanges, plate flanges, blind flange, and so on.
Characteristics and advantages:
1.High strength: The strength of butt welded connections is usually high because the welded part is integrated with the base metal, eliminating additional connecting components.
2.Good sealing performance: Proper butt welding can provide excellent sealing performance, which is very important in applications such as pipelines and containers that require sealing performance.
3.Appearance cleanliness: After welding is completed, the welded workpiece usually has a neat appearance and the welded joints are flat, reducing the need for subsequent processing.
4.Economically efficient: Compared to other connection methods, welding does not require the use of bolts, nuts, or other connecting parts, making it more cost-effective in terms of materials and costs.
5.Wide application range: suitable for welding various metal materials, including steel, aluminum, copper, etc.
For an important technology in butt welding connection, namely “resistance welding”, it is a method of generating heat through an electric current and heating the metal workpiece to a molten state. A special form of resistance welding is “resistance butt welding”, also known as “resistance butt welding”.
In resistance butt welding, the metal workpieces at both ends of the welding are connected to the power supply through electrodes. When current passes through these workpieces, heat is generated, causing the contact surface to heat and melt. Once the required melting point and temperature are reached, pressure is applied to the workpiece, connecting them together. Subsequently, stop heating and apply pressure to allow the welding area to cool and solidify. This connection method is usually used for thinner metal workpieces, such as body parts in automotive manufacturing and metal containers in container manufacturing.
Overall, as an efficient, high-strength, and widely applicable metal connection method, welding plays an important role in industrial manufacturing and construction, providing reliable connection methods for various metal structures.
