Nanosecond Precision Laser Welding Machine for Dissimilar Materials - China Suppliers & Factory Solutions
Product Description
A nanosecond welding machine is a device that uses nanosecond pulse lasers for welding. Compared with traditional laser welding machines, nanosecond welding machines have shorter pulse widths and higher peak powers, enabling faster and more accurate welding processes. The nanosecond welding machine is suitable for welding various metal materials, including stainless steel, aluminum alloy, copper alloy, titanium alloy, etc. It has a wide range of applications in fields such as automobile manufacturing, electronics, and precision machinery.
The working principle of nanosecond welding machine is to heat the material to a molten or vaporized state in a very short time through high-energy laser pulses, and then rapidly cool and solidify to form a weld seam. Due to the very short pulse width and small heat affected area, the thermal stress and deformation generated during the welding process are also small, thereby improving the welding quality and accuracy.
In addition, nanosecond welding machines can also be integrated with other automation equipment and production lines to achieve automated welding production, improve production efficiency and product quality.
Key Process Parameters of Nanosecond Welding Machine
- Pulse width: Typically between a few nanoseconds and tens of nanoseconds. When the pulse width is less than 10 nanoseconds, an extremely fast heating and cooling process is achieved, effectively avoiding the formation of heat affected zones (HAZ).
- Pulse energy: Refers to the amount of energy transmitted by each pulse. Different pulse energies must be selected based on material properties and component sizes to achieve optimal welding results.
- Solder joint diameter: Refers to the size of the solder joint formed within one pulse cycle. This can be adjusted precisely by controlling both the pulse width and pulse energy.
Additional configurable parameters include laser wavelength (e.g., 1064nm), maximum laser output power (e.g., 70W), power adjustment range (1-100%), energy fluctuation (<± 5%), and frequency adjustable range (1-2000KHz). In practical applications, appropriate process parameters must be selected based on specific welding requirements, material properties, and usage environments.
