Method and device for laser preheating control

Wenlong Chang (Inventor)

Research output: Patent


A laser preheating control method is applied to a laser preheating control device. When a tool processes a workpiece along a machining path, a laser source of the laser preheating control device outputs a laser beam to The workpiece selectively forms a laser spot on the surface of the workpiece, and the laser controller of the laser preheating control device causes the laser spot to be formed only on the moving direction of the tool on the workpiece. One of the front of the processing path is to be preheated to preheat the workpiece located in front of the processing path, thereby avoiding reheating the workpiece located behind the processing path to cause a qualitative change.
