Why does handheld laser welding require a control system

Handheld laser welding is another new application technology of laser. Its principle is to aim a highly energy dense laser beam at the material, thereby rapidly heating and melting the material locally, forming a welding interface, and ultimately achieving the welding effect. Handheld laser welding equipment mainly includes lasers, welding heads, control systems, cooling systems, etc.

Handheld laser welding has the characteristics of high efficiency, precision, strong flexibility, and low threshold for manual operation. It has obvious advantages in processing thin metal materials and irregular parts. Compared with traditional welding, the biggest difference of handheld laser welding is that it has an intelligent control system. By adjusting the corresponding parameters in the control system, handheld laser welding equipment can complete processing.

The control system on handheld laser welding is mainly designed to ensure the accuracy, stability, and safety of the welding process. The following are several main reasons for equipping control systems in handheld laser welding:

Improving welding quality: The control system can adjust the laser output power in real time to ensure stable heat input throughout the entire welding process, in order to meet the requirements of different materials and welding thicknesses. By controlling the frequency and focal length of the laser, the welding effect can be optimized to ensure the quality of the weld seam.

Reduce the difficulty of getting started: Through an intelligent control system, many complex welding parameters can be automatically adjusted or preset, thereby reducing the operator's requirement for technical proficiency and making the operation relatively simple. The parameters automatically calculated by the control system will also be more accurate, ensuring better welding quality.

Data recording and analysis: The control system can record important parameters during the welding process (such as power, speed, time, etc.), providing data support for later analysis, quality traceability, and production improvement. When problems arise, the control system can provide fault feedback and diagnosis, helping operators quickly locate the problem and handle it.

Security protection: The control system can set operational safety parameters to prevent equipment damage caused by overload, overheating, and other reasons. At the same time, protective measures can be applied to operators, such as using sensors to detect whether the laser is aligned with the workpiece. If it fails to align with the workpiece, the laser will not emit light, avoiding damage to the human body caused by the laser.

Overall, the control system in handheld laser welding systems is crucial for improving welding quality, efficiency, and safety. It ensures the consistency and reliability of the welding process through real-time monitoring, parameter adjustment, and path planning, while supporting data recording and fault diagnosis for later optimization and maintenance. Modern handheld laser welding equipment is almost equipped with advanced control systems to meet the increasing precision and efficiency requirements in industrial production.
