초록

The restraint force is required for the accurate measurement and analysis to protect weldment from residual stress. Also, this residual stress caused by cracks in weldments is often observed in the weldments of large size nozzles or radial tanks after welding. This paper is preformed to evaluate the welding restraint forces using load cell with STS304 thin plate which is used as the pressure vessel steel in the industry field. As a result, as the welding currents are higher and the welding speeds are more slowly, the magnitude of restraint force in process of the flat plate welding shows to be more large.
