Buckling of columns during welding

Original language description

The paper presents experiments of columns loaded by compressive force during welding along their longitudinal axis. A weld bead was being laid in the corner of the cross-section from the bottom of the column to its mid-height at constant load. Then, still during welding, the load was increased until the column failed by flexural buckling. Manual gas metal arc welding with carbon dioxide was used. All the columns had the height of 3 m. The tested cross-sections were HEA 100, IPE 120, IPE 160, SHS 1005, and CHS 764. The measured values were applied load, column deflections and changes in length, welding voltage, current and speed, and temperatures. The experiments were performed at the laboratory of Department of Metal and Timber Structures of Faculty of Civil Engineering of Brno University of Technology. Material properties of steel are temporarily decreased by the high temperature caused by the welding process. Analytical method is offered to design the buckling resistance of a column during welding. The cross-sectional properties are assumed to be reduced at the most dangerous height and the column is treated as stepped. The welds should be placed in short segments symmetrically. Otherwise, the deflection caused by the shrinkage of asymmetrically placed welds must be also taken into account.
