Multi-point welding method for lens processing

The invention discloses a multi-spot welding method for lens processing. The multi-spot welding method comprises a welding spot position determining method. A flux control method; according to the welding energy compensation method, more than three welding spots are arranged between a first weldment and a second weldment, the second weldment and the first weldment are in a parallel concentric circle corresponding relation, and all the welding spots are located in the range of the second weldment; before the three welding spots are welded, welding flux is added to the welding spots according to a preset welding flux amount value, when energy is added to the welding spots at the same time for welding, the welding spots are detected through a detection device, a preset value and real-time detection comparison mode is adopted as the detection mode, and when the real-time energy is lower than the preset value, the welding flux is added to the welding spots according to the preset welding flux amount value. And if
