The invention relates to the technical field of carrier module production, in particular to a carrier module PCB welding device and method. The device comprises a fixing piece and a machining piece arranged on the fixing piece. According to the welding device, when the pre-welding structure slides upwards, the welding flux flows out to wrap the pin of the electronic component, meanwhile, the supply structure is driven to reset, and when the pre-welding structure moves downwards to reset, the supply structure is driven to clamp the welding wire and drive the welding wire to enter the pre-welding structure to be heated and melted to form new welding flux; as the lengths of the welding wires are consistent when the supply structure drives the welding wires to enter the pre-welding structure every time, the amount of the welding flux formed by melting the welding wires through the pre-welding structure every time is consistent, that is, the amount of the welding flux used for welding every time in the welding machining process of the carrier module PCB is consistent, the situation that the welding flux is too little can be avoided, and the welding quality of the carrier module PCB is improved. And the condition of excessive welding flux can be avoided, so that the welding processing quality of the carrier module PCB is ensured.
