Large precision welded components for ground rails
The manufacturing and processing of large welding parts is the use of fusion welding to process and manufacture frames from components such as square pipes and iron parts. Fusion welding is a manufacturing process that uses heating, high temperature, or high pressure to join metals or other thermoplastic materials such as plastics. The welding method used in the manufacturing and processing of large welding parts is:
1. Fusion welding
Fusion welding is a method of heating the workpiece interface to a molten state during the welding process, without applying pressure to complete the welding. During fusion welding, the heat source rapidly heats and melts the interface between the two workpieces to be welded, forming a molten pool. The molten pool moves forward with the heat source and forms a continuous weld after cooling, connecting the two workpieces into one.
2. Pressure welding
Pressure welding is the process of achieving atomic bonding between two workpieces in a solid state under pressure, also known as solid-state welding. The commonly used pressure welding process is resistance welding. When current passes through the connection end of two workpieces, the temperature rises due to the high resistance. When heated to a plastic state, the connection becomes integrated under axial pressure.
3. Brazing
Brazing is a welding method that uses a metal material with a lower melting point than the workpiece as the brazing material. The workpiece and brazing material are heated to a temperature higher than the melting point of the brazing material but lower than the melting point of the workpiece. The liquid brazing material is used to wet the workpiece, fill the interface gap, and achieve atomic diffusion with the workpiece, thereby achieving welding.
The commonly used welding techniques for the manufacturing and processing of large welding parts include arc welding, argon arc welding, CO2 shielded welding, oxygen acetylene welding, laser welding, electric slag pressure welding, and other methods. The appropriate welding method can be selected according to the material and performance requirements used in the welding and processing of large frames, in order to meet customer needs.
