| Abstract: | This paper introduces the welding technology of high efficient rudder arm steel casting inlaid structure and buttering method for solving cracks on rudder arm steel casting inlaid structure.Practice indicates that buttering method has low cost,can be simply operated and carried through the heat treatment after post weld. When devising the welding groove,considers the dimension of outer diameter of 350 type small caliber welding gun's nozzle with CO2 welding and length of welding wire,and ensures the root pass to be completely fused and reduces the welding workload ASAP.The shape of groove meets the demands of welding.The rudder arm inlay welding joint passes the nondestructive test, and the quality of welds meets the demands of ISO 5817 C. |
