China Suppliers Factory Nanosecond Precision Laser Welding Machine for Dissimilar High Reflectivity Thin-Walled Materials
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.
Process Parameters
The process parameters of nanosecond welding machine mainly include the following aspects:
Pulse Width
The pulse width of nanosecond welding machines is usually between a few nanoseconds and tens of nanoseconds. When the pulse width is less than 10 nanoseconds, a very fast heating and cooling process can be achieved, thereby avoiding the formation of heat affected zones (HAZ).
Pulse Energy
This refers to the amount of energy transmitted by each pulse. For components of different materials and sizes, different pulse energies need to be selected to achieve optimal welding results.
Solder Joint Diameter
Solder joint diameter refers to the size of the solder joint formed within one pulse cycle. The diameter of the solder joint can be adjusted by controlling the pulse width and pulse energy.
In addition, the parameters of nanosecond welding machine also include laser wavelength, laser output power, power adjustment range, energy fluctuation, frequency adjustable range, etc. For example, some nanosecond welding machines have a laser wavelength of 1064nm, a maximum laser output power of 70W, a power adjustment range of 1-100%, energy fluctuation <± 5%, and a frequency adjustable range of 1-2000KHz.
In practical applications, it is necessary to select appropriate process parameters based on specific welding requirements, material properties, and usage environments.
