Title:
多層DMDプロセス用の形状によらないリアルタイムの閉ループウェルドプール温度制御システム
Document Type and Number:
Japanese Patent JP4473124
Kind Code:
B2
Abstract:
In a direct metal deposition system which builds up a metallic overlay on a substrate by moving the substrate relative to a laser in a metallic powder feed, the laser power is adjusted for successive layers by sensing the weld pool in a plurality of selected points in each layer and adjusting the power during successive layers to maintain a weld pool that corresponds to those achieved during deposition of a lower optimal layer. This compensates for heating of the substrate resulting from the deposition which tends to increase the pool size or temperature in the higher layers.
