What Is the Difference Between Single-Oscillation and Dual-Oscillation in Laser Welding Machines?

Single-oscillation system: Equipped with one galvanometer motor, the laser beam can only move in one direction, resulting in relatively simple welding patterns (e.g., sinusoidal). This system is suitable for precision welding of small products.

Dual-oscillation system: Equipped with two galvanometer motors, enabling the laser beam to move simultaneously in two directions. This allows for the creation of complex welding patterns (e.g., circular, square, elliptical, figure-8, ∞-shaped, S-shaped, C-shaped, etc.). Complex weaving patterns effectively enhance the molten pool and reduce welding defects, making the dual-oscillation system more suitable for large-area welding of large workpieces.

What Are the Oscillating Modes of the Dual-Oscillation System?

• Circular oscillating mode: The laser beam oscillates along a circular trajectory during welding, optimizing the distribution of weld penetration and width, suppressing porosity defects, and improving weld quality.
• Sinusoidal oscillating mode: The laser beam oscillates along a sinusoidal trajectory, evenly distributing laser energy, reducing penetration differences, optimizing molten pool flow, and improving weld formation quality.
• Figure-8 oscillating mode: The beam oscillates along a figure-8 trajectory, effectively suppressing porosity defects and enhancing welding results while stabilizing the keyhole to improve overall weld quality.
• Dual-wedge oscillating mode: Achieves a spiral-like weld through a dual-wedge trajectory, suitable for thick-walled pipe welding, flange welding, and other processing needs, offering high repeatability and stability.
• Linear oscillating mode: The beam oscillates along a straight-line trajectory, suitable for simple structural welding requirements.
• S-shaped oscillating mode: The beam oscillates along an S-shaped trajectory, improving heat input distribution and enhancing weld quality.
• Ring-shaped oscillating mode: The beam oscillates along a ring-shaped trajectory, suitable for welding complex structures requiring uniform heating.
• Dot-shaped oscillating mode: The laser beam oscillates in a dot-like trajectory, ideal for precision welding or localized heating.

Why Choose a Dual-Oscillation Laser Welding Machine?

The dual-oscillation laser welding machine can achieve more complex weld weave patterns, balance the torque generated during welding, reduce welding deformation, and improve weld quality. Compared to conventional welding methods, dual-oscillation welding is faster, more efficient, and produces smoother, flatter welds, reducing the need for subsequent grinding. It meets more stringent operational requirements.

What to Consider When Purchasing a Laser Welding Machine?

1. Brand selection

   Choosing a reputable brand with reliable after-sales service ensures better machine quality and support. A strong supplier with comprehensive service can provide technical assistance, maintenance, and spare parts supply.

2. Laser power selection

   Laser power is a core parameter of a laser welding machine, directly affecting welding depth, speed, and quality. The appropriate power should be selected based on material thickness and welding requirements:

   - For thin metal materials, lower laser power is sufficient.

   - For thicker materials or high-speed welding demands, a higher-power machine is recommended.

3. Budget planning

   When selecting a machine, evaluate your budget reasonably. High-end machines offer superior performance but come at a higher cost and may include unnecessary features. At the same time, avoid blindly pursuing low prices. Opting for a cost-effective model (balancing functionality and performance while minimizing costs) is more practical.

4. Operational costs

   Ensure the machine has a user-friendly interface and intuitive operation to reduce operator training time and learning difficulty.

5. Long-term usage planning

   Consider the initial investment, shipping costs, and operational expenses (such as electricity and maintenance). A machine that is easy to maintain with low upkeep costs offers better long-term economic benefits.

6. Configuration selection

   Laser welding machines come with various configurations, including laser welding guns, laser generators, control systems, cooling systems, etc., with significant price differences.
