STUDY ON THE ANGULAR DEFORMATION OF LASER CLADDING ON THIN PLATE
Laser cladding stainless steel alloying powder on 316 stainless steel thin plate substrate with thickness of 1.2mm was carried out by use of ROFIN DY011 Nd:YAG laser equipped with a coaxial powder feed nozzle. The effects of laser power, scanning speed and line energy on the deformation extent of the thin plates during laser cladding processing were studied systematically. The experimental results demonstrate that the deformation of 316 stainless steel thin plate is serious, and the thin plates become saddle form after laser cladding. The bending angle of substrate increases with the increase of laser power, scanning speed and line energy firstly, and then decrease when the parameters are bigger than some critical values. The bending extent is related to the yield strength, temperature gradient and size of plastic zone of the substrate.
