SAMPLE to determine mechanical properties fusion zone aluminum alloy welded joints AT fatigue tests

摘要

The invention relates to the field of welding of aluminum alloys, namely, to the samples to determine the mechanical properties of the fusion zone of welded joints during fatigue testing. The sample is formed as a plate width of 5-10 sheet thicknesses in the middle of which is the weld. At the boundary of the weld and the base metal stress concentrator is configured as a through hole diameter (0,12-0,4) h, where h - the thickness of the sheet, and the hole axis oriented at an angle of 20-28 ° relative to the normal to the sample surface.
