This robot applies weling paste for automotive coolers. The special welding paste achieves a high quality finish in the parts. After the welding paste is applied, the parts are treated with heat in an oven, that melts the paste and welds the components.

The paste needs to be applied accuracely. There is a high variabilty along the production process, because of the nature of this special paste. It needs to be calibrated after certain periods of time.

This operation was done previously by a skilled worker.

The robot introduces improvements in the process:

• repeatability
• cost save
• automatic paste calibration

Decuna developed this work under the "turnkey" concept. We dealt with mechanical design, supplier management, integration, production start and support all over the process.

Application video

The application can be seen in this video from different angles. A special tooling applies the paste in the inner side of the part, and the robot impregnates the outer side. The complete piece contour is covered with the robot arm movement and the paste nozzle.
