The COVID-19 health crisis has wrought substantial challenges on individuals, societies, and organizations worldwide that have significantly transformed the way people function in their workplace a daily basis, resulting heightened levels of physical, psychological, social deprivation. Available empirical evidence field education explicitly foregrounded negative impact pandemic teachers’ well-b...
Shrink-fitting, a common bonding technique in metal assemblies, was used for mortise and tenon wood joints. The joints had considerable strength. Shrink-fitting yielded joint strengths comparable to those obtained by using several welded dowels. Increasing the number of welded dowels, however, produced joints of higher strength than those bonded just by shrink-fitting. Combining in the same joi...
The friction welding of Zr55Al10Ni5Cu30 bulk metallic glasses (BMG) has been tried. An apparatus for the friction welding of BMGs adopting a pneumatic cylinder and gripper based on a conventional lathe, and a welding process which provides a sufficient cooling rate after welding were devised. Friction time and friction pressure were chosen as the control parameters in the friction welding proce...
The reliability of welded structure can be evaluated through welding residual stress analysis and fatigue strength assessment. In this study, welding residual stresses of multi-pass dissimilar material welded joint between alloy 617 and 12Cr steel were analyzed numerically and experimentally. Fatigue strength was then assessed in the air. Based on results of welding residual stress analysis and...
There are many industries where austenitic stainless steel needs to be welded specially in power generation industries. Unfortunately the austenitic stainless welding has several fabrication and metallurgical drawbacks when welded by using conventional fusion welding methods, which can often leads to in-service failure. The most pronounced fabrication faults are hot cracks due to inadvertent us...
Introduction. Friction stir welding is widely used due to certain advantages of this method. Factors that reduce the strength joints made high-strength aluminum alloys are considered. When flat sheets, an effective way increase weld edge thickening. The paper proposes a method for such A device developed, calculations and experiments carried out. Materials Methods. Laboratory equipment has been...
