Resistance diffusion welding, also known as resistance pressure welding or resistance upset welding, is a solid-state welding process that involves applying pressure and heat to the surfaces of two materials to be joined. The process relies on the diffusion of atoms at the interface, resulting in a metallurgical bond. Here's how resistance diffusion welding can be applied in the context of soft connection copper bars.
Advantages of Resistance Diffusion Welding in Soft Connections:
1.High Conductivity for Multilayer Copper Foils Flexible BusBars:
The solid-state welding process maintains the high electrical conductivity of copper.
2.Metallurgical Bond for Flexible BusBar:
Creates a metallurgical bond without the need for filler materials, ensuring a strong connection.
3.Minimized Heat-Affected Zone for Copper Flexible BusBar:
Since it is a solid-state process, there is minimal heat-affected zone, preserving the material properties.
4.No Melting for Multilayer Bus Bar:
The process occurs without melting the materials, preventing issues related to liquid metal reactions.
5.Repeatable Process for Flexible Copper BusBar:
Resistance diffusion welding is a repeatable and controllable process, allowing for consistent results.
The application of resistance diffusion welding in soft connection copper bars provides a reliable method for creating joints with high electrical conductivity and mechanical strength while preserving the soft properties of copper. This makes it suitable for various electrical and industrial applications where flexibility and conductivity are essential.
