In-situ metallurgy method based on simultaneous feeding of multiple laser wire powder

The invention discloses an in-situ metallurgy method based on simultaneous feeding of multiple laser filament powder, which comprises the following steps of: acquiring the position and intensity data of each laser beam in real time through a sensor of a laser phase control unit; basic parameters including laser transmission path parameters and optical element parameters are called, a multi-laser-wire-powder simultaneous feeding light field model is constructed, and parameters of the multi-laser-wire-powder simultaneous feeding light field model are calibrated based on data collected by a sensor; according to a pre-constructed laser phased array adjustment algorithm, the deviation of each laser beam is analyzed and calculated in combination with sensor data, and the focal length and the strength of each laser beam are adjusted, so that the laser beams are intersected in a welding area; output of a laser phased array adjustment algorithm is fed back to a control system of the laser through a feedback system, re
