Stress Intensity Factor Expression for Welded Butt Joint with Undercut and Inclined Lack of Penetration Defects considering the Effect of Joint Shape
In this paper, the stress intensity factor (SIF) expression for defected butt welds containing undercut and inclined lack of penetration (LOP) subject to far-field tensile stress is derived. Some of the standards such as ISO 5817 and BS EN 25817 have specified allowable limits for the length of the undercut and LOP defects and for the height of the weld. In addition, EN 29692 standard has deter...
متن کاملEffect of tool position on microstructural and mechanical properties of friction stir butt welded joint of AA2024–AA7075 dissimilar alloys
In this research, butt joining of Al2024 and Al7075 plates were performed by Friction Stir Welding (FSW) and the effect of tool position on microstructural and mechanical properties in about 1 mm from center line of joint towards the advancing side (AS) and the retreating side (RS) was investigated at three positions of +1, 0, -1 mm. In this regard, the plates of Al2024 and Al7075 were selected...
متن کاملIdentification and Suppression of Thermal Reflections in Infrared Thermal Imaging
Thermal reflections are a common source of problems in interpreting infrared (IR) thermal images. In particular, atomically smooth surfaces like glass, metals, or wet surfaces, and also brick and concrete, may easily give rise to reflections of infrared radiation from often uncared sources. If unnoticed, these thermal reflections may give rise to misinterpretations of the object temperature. Af...
متن کاملThe Effect of the AA7075 Interlayer on the Microstructure and Mechanical Properties of the AA1050 Butt Joint Welded by FSW
In this research, the FSW Butt joint of commercial aluminum 1050 was investigated by using the 7075 aluminum alloy interlayer on the linear velocity of 30, 50 and 100 mm / min, and rotational speeds of 800 and 1200 rpm. A threaded cylindrical tool was used for joining of the 5 mm sheets. The OM, SEM, microhardness and tensile tests were done. The results shows that in sample with an interlayer ...
