Construction of the Remote Welding System based on Power Line Communication

摘要

Abstract Remote welding technology plays an important role in the construction of national key projects. Instead of manual welding and full-autonomous welding, it is the best way to apply remote welding technology to practical engineering by employing a special robot. This study uses the remote welding power supply cables as the carrier to construct the power line communication network. The key technical problems of the power line communication for complicated electromagnetic environment are proposed in this paper. On this basis, the welding parameters and the environment parameters are transferred to the local control unit, by the power line communication network. The influence rule on weld formation, microstructure, mechanical properties, and welding defects can be revealed by analyzing the above factors. This study explores a feasible way for the robot remote welding by the way of integration innovation. It will lay a foundation for the application of the robot remote welding technology in the construction of national key engineering.
