The invention relates to an intelligent AOI welding selecting system and method. The system comprises welding selecting equipment, a server, AOI equipment and identification equipment, wherein when a PCB plate is identified and image-shot by the AOI equipment, under-quality welding spot coordinate information and corresponding identification information of each PCB plate can be sent to the server; the information is then stored in the server; the welding selecting equipment comprises a selecting spraying machine and at least one selecting solder-welding machine; the selecting spraying machine and the selecting solder-welding machine are both provided with an identifying unit; and the selecting spraying machine and the selecting solder-welding machine are both connected with a server signal. Under-quality welding spots of the PCB plate and corresponding bar code information are collected by the server in the previous phase; during the renovation, under-quality welding spot coordinate information of the PCB plate is called by the selecting spraying machine and the selecting solder-welding machine via the identifying units and renovation is conducted according to the under-quality welding spot coordinate information; and labor cost and site cost can be reduced.
