Introduction
Self-Fusion welding is a pivotal technology in the realm of modern welding applications, offering efficiency, precision, and excellent weld quality. In this technical article, we will compare two prominent self-fusion welding machines: the diode laser welding machine and the fiber laser welding machine. By examining their respective characteristics, advantages, and limitations, we aim to provide valuable insights for selecting the optimal welding solution based on specific requirements.
1.Diode Laser Welding Machine
The diode laser welding machine offers a host of compelling advantages, making it a preferred choice for various welding applications.
1.1 Smooth Surface and Beautiful Weld Seam Shape
One of the standout features of the diode laser welding machine is its ability to produce weld seams with exceptionally smooth surfaces and aesthetically pleasing shapes. This attribute is especially beneficial in industries where visual appearance is of utmost importance, such as automotive, electronics, and architectural applications.
1.2 Stable Welding Process with Minimal Spatter
The diode laser welding process exhibits remarkable stability, resulting in reduced spatter during welding. The low spatter generation enhances the efficiency of welding operations and reduces post-weld clean-up efforts, making it an ideal solution for high-volume production environments.
1.3 Large Spot Size and Uniform Energy Distribution
Equipped with a large spot size and uniform energy distribution, the diode laser system allows for greater tolerance of joint gaps between plates. It excels in handling gap widths ranging from 0.05mm to 0.2mm, making it suitable for applications where precision assembly is not the primary concern.

2.Fiber Laser Welding Machine
The fiber laser welding machine is another reliable option in self-fusion welding, offering distinct features that cater to specific welding demands.
2.1 Well-Formed Welds
Similar to the diode laser, the fiber laser welding machine delivers well-formed welds characterized by fine precision and excellent consistency. This feature is invaluable in applications that require superior weld quality and durability.
2.2 Relatively Stable Welding Process
The fiber laser welding process is relatively stable, contributing to enhanced efficiency and consistency in welding operations. Its stable nature makes it well-suited for a broad spectrum of industrial applications.
2.3 Small Laser Spot Size and Assembly Precision
The fiber laser system employs a smaller laser spot size, demanding higher assembly precision of the welding parts. This attribute is particularly advantageous in applications necessitating intricate and precise welds, such as microelectronics and medical devices.
2.4 Limitations in Handling Larger Gaps
However, it is important to acknowledge that the fiber laser welding machine may encounter challenges when dealing with larger gaps between plates. Gap widths exceeding 0.15mm may result in a phenomenon known as “collapse,” impacting weld quality and potentially requiring rework.

Conclusion
The choice between the diode laser welding machine and the fiber laser welding machine hinges on specific welding requirements and application scenarios. The diode laser system is favored for its smooth weld surface, stable welding process, and large gap tolerance. Conversely, the fiber laser system excels in delivering precise welds but demands higher assembly accuracy and may have limitations in handling larger gaps.
By carefully considering the unique characteristics and performance of each self-fluxing welding machine, industries can make informed decisions to optimize their welding processes and achieve exceptional weld quality. Ultimately, selecting the most suitable technology will pave the way for enhanced productivity, improved weld integrity, and overall success in welding applications.
