The application of concurrent engineering for designing and manufacturing welding production lines and jigs was discussed, and a new idea for using concurrent engineering to design and manufacture welding production lines with reduced investment, time and error was proposed. The design method of flexible welding jigs and the task scheduling of welding production line design and manufacture were emphasized. It is aimed at the jig design scheme by using the design of flexible welding jigs based on jig-base, so that the design process of welding jig is speeded up, the rationality of the design is improved and the cycle of welding jig design and manufacture is shortened, thereby the bottleneck of jig welding based on the concurrent is solved engineering environment. The strategy of design task scheduling was analyzed, showing that scientific task scheduling is one of the keys to fullfill the task of designing welding production lines and jigs based on the concurrent engineering environment.
