In order to obtain the best process parameters of the titanium alloy single-track and single-layer laser cladding, the orthogonal experiment method was used, and have designed laser cladding forming test, found out the influencing rule of laser power, scanning speed and powder feed rate on the cladding layer geometric size. And contrast different process conditions of the cladding layer surface and cross section爷 s quality,through the contrast analysis, get a group of fine process parameters for single-track and single-layer cladding and provide data reference for later laser cladding forming test .
