Residual Stresses in Steel Plate Due to Gas-Cutting - An Interim Report

摘要

The investigation concerns the oxy-acetylene gas-cutting of mild steel plate of thickness 6-40 mm. Residual compressive strains measured directly are broadly consistent with predictions based on experimental total heat inputs. Measured heat inputs due to the preheating flame alone can be correlated with published Soviet results. Oxidization heat inputs reported by Soviet workers are, however, grossly in excess of the results obtained in the present investigation. The source of this discrepancy is subject to further study.
