Good Welding Quality
Robotic laser welding is characterized by high precision, firmness, and efficiency. It achieves high-quality welding results. The welds are strong and almost flawless, not only high in strength but also beautiful. This welding method does not require post-processing, reduces labor costs and labor intensity, greatly improves production efficiency, and saves production costs.
Training Services
We provide customers with at least 7 days of training at the customer’s workshop, which will ensure that customers can really use the machine. We will also give customers video operations and documents. Once our customers forget how to operate, they can read and check at any time.
Single Robot Laser Welding Machine
- The robot can perform complex welding tasks using preset paths and parameters to achieve consistent operation.
- Flexibility: It can quickly adapt to different welding tasks and workpiece shapes through programming and is suitable for multi-variety and small-batch production.
- Safe operation: Reduces manual intervention, reduces the risk of personnel exposure to laser environment, and improves operation safety.
Semi-automatic Robot Laser Welding
- Semi-automatic automation: During the welding process, the equipment can automatically perform welding operations, but some manual work is required.
- Good adaptability: It is suitable for the production of medium-volume products, especially some workpieces with complex shapes or requiring manual judgment.
- Relatively low cost: Since some functions are completed manually, the equipment investment is relatively small, which is suitable for small and medium-sized enterprises or production environments with limited funds.
Our Robotic Laser Welding Machine Solutions
As a fully automatic welding machine, the entire welding process is fully automated, including loading, positioning, welding and unloading of workpieces. The fully automated production process has a fast and stable production speed, which can greatly increase output and shorten production cycle.
The laser welding workstation integrates Yaskawa robots,welding positioners, high-power fiber lasers source, cooling systems, etc. to achieve high-precision, automated laser welding. The workstation is a closed working space to prevent laser leakage and welding spatter, ensuring safe operation.
