RJH615 Laser Welding Robot





Working radius




Main Features

  • RJH615 is a high-speed and high-precision 6-axis robotic arm
  • Two models: 2m arm span with 15kg load capacity; 1.8m arm span with 20kg load capacity
  • Forearm and wrist with large-diameter hollow design, suitable for arranging tool lines in welding, grinding and etc. scenarios which can effectively minimize end line interference
  • Extremely high speed and welding precision
  • Robotic arm for laser welding, Mig welding and etc.


  1. The laser and Mig welding robot is equipped with an easy-to-use HsPad teaching pendant, which makes it effortless for users to operate.
  2. It can be connected to industrial Ethernet such Profinet through the gateway device to realize data communication between the controller and external PLC.
  3. Intelligent trajectory optimization strategy for optimal control performance.
  4. Integrated with various sensor such as vision sensors, torque sensors, stability sensors and etc. Alert mode and assist mode combined with sensors.
  5. Based on rich practical cases and integration of processing technology, we have developed a variety of process packages such as welding process packages, which greatly reduces the difficulty of programming.
  6. RJH615 laser welding robot has double guarantees of performance and stability: the linear trajectory accuracy is as high as 0.08mm and the arc trajectory accuracy is as high as 0.2mm when the speed is 100%.
  7. It provides remote access monitoring to view the running status of the robot in real time, which is helpful for remote troubleshooting.
  8. RJH615 Mig welding robot can provide professional and customizable services, so that beginners without welding experience can easily get started.
