Abstract: A robot-based laser cladding method for membrane wall is provided, and includes: step 1: installing a laser line scanning sensor and a laser cladding head in parallel with a forward-bias in feed direction; step 2: storing extracted feature points into a feature point buffer; step 3: installing an industrial camera at a certain angle with the laser cladding head, making a collection range of the industrial camera follow closely a current cladding position; a robot-based laser cladding system for membrane wall is provided, and includes a data collection system, a data processing system, a detection and correction system, and a motion control system. A speed dynamical prospect is used for performing a speed planning. The above speed dynamical prospect dynamically adjusts a prospective read-ahead segment number N, compared to planning method with fixed read-ahead segment number, the dynamic speed prospect has a smoother cladding speed and more stable cladding quality.

Abstract: A laser scanning welding method for lap joints based on linear energy density regulation includes the following steps 1 to 5. Step 1: welding surfaces of two metal plates of a same material are wiped with anhydrous ethanol; step 2: the two metal plates of a same material are placed in an overlapping manner on a welding operation platform; step 3: a position of a welding focus plane is adjusted; step 4: process parameters of laser scanning welding are set; step 5: parameters of a circular scanning power regulation strategy is calculated and power correction values for the lower plate is set; and step 6: lap welding of the two metal plates of the same material is completed by processing according to the circular scanning power regulation strategy and the power correction values.

Abstract: A system for controlling overlapping in single-layer laser cladding of a shaft-like workpiece includes an acceleration time calculation module, a feed shaft displacement calculation module and a module for adjusting an initial zero position of a laser head in a feed direction. Using the system, the motions of the spindle and the feed shaft are planned based on an S-curve acceleration and deceleration method. The motion planning is dynamically adjusted considering the overlapping rate and the clamping allowance of the workpiece to be cladded in a feed direction.
