Introduction

Robson Fernando De Oliverira Pereira is a notable inventor based in Sao Jose dos Campos, Brazil. He has made significant contributions to the field of welding technology, particularly through his innovative patent related to friction stir welding.

Latest Patents

Robson holds a patent for "Friction stir welding spindle downforce and other control techniques, systems and methods." This invention focuses on friction stir welding equipment control force spindle, which is designed to be mounted in an orbital head housing. The system utilizes a coaxial sensor to measure downforce, while an axial electrical actuator dynamically corrects the axial tool position during the welding process. This ensures that controlled downforce is maintained according to pre-set parameters based on numerical control. Additionally, the equipment monitors and controls spindle rotation speed, welding speed, acceleration speed, and downforce through closed-loop control functions. A laser system may also be employed to scan the backing surface before welding, allowing for corrections to the original tool path. Furthermore, a precision alarm system is integrated to ensure safe welding and prevent tool collisions with the backing surface.
