FANUC 推出 CRX 激光焊接系统，面向多品种小批量管道焊接
High-Speed, Low-Distortion Pipe Welding!
发那科（FANUC）开发出 CRX 激光焊接系统，将手持式激光焊接机与协作机器人集成，用于多品种、小批量管道焊接自动化。该系统通过拖拽专用激光焊接图标编程，支持直接手动引导机器人和平板屏幕拨盘微调，降低了对自动化专业人员的要求。焊接时激光头朝下，机器人控制管道相对固定焊头恒速旋转，激光功率随机器人速度变化自动同步，以获得一致焊缝质量并减少变形。系统用单一激光光源自动完成焊接与焊缝变色清除，省去焊后矫正和去色工序。安全方面配备接触停止功能，检测到人与机器人接触即停机并自动关闭激光，程序不完整（含死循环）时报警停机。在本次国际焊接展上，发那科现场演示该管道焊接方案并展示焊接样件。

FANUC CORPORATION
FANUC is promoting automation in high-mix, low-volume welding sites. There are various welding methods used for joining metal materials, including arc welding, TIG welding, and ultrasonic welding. Laser welding is a technology that uses a focused high-intensity laser beam to join metal materials.
Laser welding machines provide several benefits, including the ability to (1) perform low-heat-input, low-distortion welding, (2) achieve consistent weld quality with ease, and (3) carry out overlap welding. Manual laser welding machines, which allow operators to perform laser welding with a handheld torch, are becoming increasingly popular in manufacturing sites.
To improve productivity through labor savings and ensure high-quality welding, FANUC has developed a CRX laser welding system that integrates a manual laser welding machine with a collaborative robot.
Challenges in High-Mix, Low-Volume Welding Operations
In general, welding operations face the following challenges.
- Difficulty in securing personnel with automation expertise.
- Time-consuming post-welding processes, such as distortion correction and discoloration removal.
- Ensuring workplace safety during the transition from manual operations to automated processes.
To address these challenges, FANUC has developed a CRX laser welding system.

Easy to use
- Dedicated Laser Welding Icons
→ Easy program creation with drag-and-drop icons - Multiple Intuitive Operation Methods for Users of All Skill Levels
→ Intuitive robot operation through direct hand-guiding
→ Intuitive fine adjustment using an on-screen dial on the tablet.
Reduced process time through improved welding quality
- Safe and low-distortion welding
→ Safe downward-facing laser torch position
→ Consistent weld quality is achieved by controlling the robot speed and rotating the pipe at a constant speed relative to the fixed welding torch.
→ Automatic laser power control synchronized with robot speed changes for consistent weld quality. - Automated removal of weld discoloration
→ Automated welding and discoloration removal using a single laser source
Easy and safe operation, even for users with no robot experience
- Contact stop function (automatically stops the robot safely when contact between a person and the robot is detected.)
→ When the robot stops, the laser is automatically turned off to ensure safety. - Automatic protection against programming errors, including infinite loops
→ Alarm stop for incomplete programs
At this International Welding Show, FANUC is showcasing an automation solution for pipe welding applications that cannot be addressed using conventional positioners. Please see the robot demonstration and examine the welded pipe samples.
