The invention relates to a manufacturing method of a launching barge rocker arm hinged support. A bed-jig for manufacturing the rocker arm hinged support is firstly manufactured, assembly and welding processes of a rocker arm hinged structure are performed on the bed-jig, the welding process is carried out after assembly is fully completed, by using the bed-jig, horizontal overhead position welding in the traditional welding process is changed into horizontal fillet welding, thus the operation difficulty is lowered, the accuracy and efficiency of welding are improved, synchronous symmetrical welding from the middle to both ends is performed, a single welding method in the prior art is changed, and thus structure deformation due to too high local temperatures in the welding process can be effectively avoided. According to the invention, the special bed-jig is designed, structure assembly and welding processes of the rocker arm hinged support are optimized, the manufactured rocker arm hinged support can meet the requirements for precision and structural strength, correction work in view of the structural deformation can also be effectively avoided, thus the production difficulty is reduced, the efficiency is greatly improved favorably, and the cost is reduced.
