In manufacturing welding scenarios, different products, materials, and thicknesses often require adapting to different welding processes—some need fast continuous welding, some need precise spot welding, and others require minimizing thermal deformation. This makes many enterprises wonder: as a "versatile" welding equipment, can laser welding machines switch between different welding modes? The answer is yes! High-quality laser welding machines not only support switching between multiple welding modes but also can adapt to multi-scenario production needs through flexible adjustments. Below, we will detailedly answer this question from aspects such as mode types, switching logic, and industry applications.
3 Common Core Welding Modes of Laser Welding Machines
The mode switching of laser welding machines essentially adapts to different welding needs by adjusting the laser output method and energy parameters. The mainstream core modes include 3 types:
Continuous Wave Welding Mode: The laser outputs energy continuously, featuring fast welding speed and uniform weld seams. It is suitable for thick plates (2-10mm) and workpieces with long welds, such as the splicing welding of rail transit components and energy storage boxes;
Pulse Wave Welding Mode: The laser outputs in pulses, with concentrated energy and a small heat-affected zone, enabling precise control of welding depth. It is suitable for thin plates (0.1-2mm) and precision components, such as the spot welding of aerospace small parts and electronic components;
Scanning Welding Mode: Controls the movement of the laser spot through a scanning galvanometer, enabling multiple forms such as spot welding, seam welding, and curve welding. It is suitable for workpieces with complex shapes, such as the welding of new energy battery tabs and special-shaped structural parts.
In addition, some high-end equipment also supports advanced modes such as modulated wave and dual pulse, further expanding the application range.
Why Is Welding Mode Switching Necessary? The Core Is "Adaptability" and "Efficiency"
A single welding mode cannot meet the diverse production needs. The core value of mode switching is reflected in 3 aspects:
Adapting to different materials: Materials such as stainless steel, aluminum alloy, and copper have different thermal conductivity and melting points. For example, aluminum alloy requires high-energy continuous welding, and copper parts require pulse mode to reduce spatter. Switching modes can avoid problems such as burn-through and incomplete penetration;
Adapting to different thicknesses: Pulse mode is used for thin parts to prevent thermal deformation, and continuous wave mode is used for thick parts to ensure welding strength. It is possible to produce multi-specification products without replacing equipment;
Improving production flexibility: For enterprises with small-batch and multi-variety production, switching modes can reduce equipment investment, allowing one machine to complete multiple processes and lower production costs.
How to Switch Welding Modes on Laser Welding Machines? The Operation Is Not Complicated
The core of mode switching for high-quality laser welding machines is "software setting + parameter matching," which does not require complex modifications and has simple steps:
Software selection: Directly select the corresponding welding mode (such as "Continuous Wave" or "Pulse Wave") through the touch screen of the equipment control system or computer software;
Parameter adjustment: Adjust parameters such as laser power, frequency, pulse width, and welding speed according to material, thickness, and weld requirements (manufacturers usually provide parameter reference tables);
Test welding verification: Conduct small-batch test welding after switching, check the weld strength and appearance, and fine-tune parameters according to the actual effect to ensure they meet production requirements.
It should be noted that the fluency and stability of mode switching depend on the quality of the equipment's core control system and laser source, which is also a key consideration when selecting equipment.
Practical Application Scenarios of Mode Switching in Different Industries
The mode switching function is widely used in mainstream industries, directly solving production pain points:
Rail transit industry: Continuous wave mode is used for welding car body frames to ensure strength, and pulse mode is switched for welding precision interior components to reduce deformation;
New energy storage industry: Pulse mode is used for spot welding of battery pack tabs, and continuous wave mode is used for box splicing, with one equipment covering the entire battery production process;
Aerospace industry: Scanning welding mode is used for precision structural parts to adapt to complex curves, and continuous wave mode is used for thick-walled components to ensure welding depth, balancing precision and strength.
3 Key Points for Choosing a Laser Welding Machine with Switchable Modes
Not all laser welding machines can achieve stable mode switching. When purchasing, it is necessary to focus on 3 key points:
Compatibility: Confirm the types of modes supported by the equipment and whether they cover the needs of your own production (such as whether it supports dual modes of pulse and continuous wave);
Operability: Whether the control system is intuitive and easy to understand, and whether parameter adjustment is convenient, avoiding complex operations that affect production efficiency;
Stability: After switching modes, whether the laser energy output is uniform and the weld quality is consistent, avoiding a decline in product qualification rate due to insufficient equipment performance.
