What is the CTC020-HJ2027L?
The CTC020-HJ2027L is the laser-optimized variant of the 20 kg CTC-HJ collaborative arm. It combines the longest reach in the series (2027 mm) with pre-configured interfaces for laser welding heads and process sensors.
Key Features
- Long-Reach Laser Welding: 2027 mm reach allows large-part laser welding without moving the robot base
- 20 kg Payload for Heavy Laser Heads: supports large fiber laser heads, fume extraction, and seam tracking equipment
- Hybrid Configuration: can switch between laser and GMAW processes on the same arm by changing the end effector
- Hand-Guide Teaching for Large Parts: teach long seam paths by manually guiding the arm instead of pendant programming
Typical Applications
This system is widely used in the following industries and scenarios:
- Large Battery Enclosures: laser seams for EV battery trays and enclosures up to 2 meters
- Heavy Sheet Metal Laser Welding: stainless steel and aluminum panels for construction and transport equipment
- Hybrid Thick Plate Welding: combining laser and GMAW for thick-section joints
