The Forming Control Method of Double-Layer and Multi-Track Stacking Laser Cladding Applied on Crankshafts Restoration

Response surface methodology was adopted to establish the mathematical model between the parameters (overlap ratio, Y-axis lift, and X-axis offset) and responses (non-fusion area, flatness ratio, and width of clad). The results indicated that the non-fusion area reduced at first and increased afterwards as overlap ratio decreased and Y-axis lift increased, while gradually reduced when overlap ratio increased and X-axis offset decreased. The...
