A laser welding robot is a high-end automated equipment that combines high-precision laser welding technology with flexible industrial robot technology. It typically consists of a high-power fiber laser, a multi-axis industrial robot (usually 6 axes), a laser welding head (with oscillation or galvanometer functions), a wire feeding system (optional), a vision positioning system, a weld seam tracking system, and integrated control software.

This system utilizes the high flexibility of the robotic arm to precisely guide the laser beam to the welding position on the workpiece, achieving non-contact, high-speed, and high-quality welding operations. Compared to traditional arc welding robots, laser welding robots offer revolutionary advantages in terms of heat-affected zone, welding deformation, and welding speed.

1. "High Precision and High Quality:"

High aspect ratio: The "keyhole" effect produced by laser welding results in a deep and narrow weld, achieving excellent single-sided welding with double-sided forming.

Small heat-affected zone: Highly concentrated laser energy and low heat input result in minimal workpiece deformation, making it particularly suitable for welding precision parts or thin plates.

Aesthetically pleasing welds: Smooth surface formation eliminates the need for subsequent grinding.

2. "High Speed ​​and High Efficiency:"

Fast welding speed: Compared to traditional argon arc welding or electric arc welding, laser welding speed can be several times or even ten times faster, significantly reducing processing time per piece.

High uptime: Robots can operate continuously 24 hours a day, enabling unmanned production with automated loading and unloading.

3. "High Flexibility and Adaptability:"

Good accessibility: 6-axis robots can reach complex curved surfaces, internal corners, deep cavities, and other locations inaccessible to traditional automated equipment.

Simple programming: Supports offline programming (OLP) and teach-and-playback; switching products only requires changing the program, making it suitable for flexible production of multiple varieties and small batches.

Real-time Monitoring: Typically integrates visual positioning and weld seam tracking functions, it can automatically identify weld seam position deviations and correct them in real time, reducing the stringent requirements for tooling precision.

Stable Process: Laser output is unaffected by electromagnetic interference, and combined with robot repeatability (typically within ±0.05mm), it ensures consistency in mass production.

5. Non-contact Machining

Low Tool Wear: Compared to spot welding electrodes or contact welding tools, laser non-contact machining eliminates mechanical stress and tool wear, reducing maintenance costs.
