| Abstract Scope |
During the laser cladding process, the melting and solidification of the melt pool results in rapid temperature change in the heat-affected zone (HAZ); as a result, pores cracks, and thermal deformation can occur. So, the accumulated heat in the HAZ must be properly controlled during the laser cladding process for rolls. So, in this study, thermal profile behavior on laser-cladding were analyzed under different process conditions based on a deep learning. The changing thermal profile during the process was photographed using a thermal imaging camera to quantify the temperature distribution around the laser, melt pool behavior over time, and overlap of successive layers. WC-Ni based powder was used for the cladding, and SCM 440 Steel was used as the substrate material. Five process conditions were considered: laser power, cladding speed, powder feeding rate, optic and offset. The results showed that the proposed model accurately quantified and predicted the thermal profile. |
