COMPUTER-ASSISTED WELDING ROBOT FOR STEEL STRUCTURES

This paper introduces the application of a robot to CO2 gas shielded arc welding in the construction of steel structures. The authors have developed a horizontal position multilayer welding system by introducing a robot to the CO2 gas shielded arc welding of steel structures where semiautomatic welding has been used. In this paper, the authors first explain the structure of a welding robot system, followed by the results of a mechanical property test consisting of a tensile, impact test (based on the Japan Industrial Standard) and a full-size three-point bending test.
