“…The square ring model made from aluminum was used to make the pink silicon mould owing to its ease of machinability, wide availability and cost-effectiveness [15], Figure 1a. The geometry of the square ring model had an internal diameter (ID) of 121.5 mm � 0.1 mm and a cross-section of 6.98 mm � 0.1 mm, Figure 1b.…”

Transportation and controlling fluid flow under high pressures in pumps, valves, boilers and heat exchangers is a common exercise in the industries. The main challenge, however that has confronted designers and manufacturers of pumps and valves along with those responsible for the maintenance and upkeep of such types of machinery is managing leakages at the positions where the seals are used. One fundamental feature of seal packing is the ability of the seal to ′flow′ into the groove spaces and effectively block fluid from passing through them. The square ring has shown good ‘flow’ behavior in addition to offering low contact stresses. This research seeks to investigate the performance of the square ring. The Hertz contact theory and photoelastic experimental hybrid method are used in the study of the performance of the square ring under a squeeze rate of 20 % and varying internal pressure. It was observed that while increasing the applied internal pressure, the deformation length and angle increased due to the high stresses produced by the applied pressure. Additionally, was initiated at an internal pressure of 0.98 MPa.

“…Due to these favorable characteristics, aluminum is increasingly used in the automotive industry. In the USA, for example, the trend of increasing the use of aluminum lasts over 50 years and it is predicted that by 2028, about 256 kg of this metal will be installed in passenger and light trucks, Figure 3 [15][16][17] Figure 3: Trend of Al use in passenger and light truck vehicles in the USA Also, it is predicted that by 2030, about 10 million tons of aluminum will be installed in electric and hybrid vehicles, which is 10 times more than the current situation. As an example, the e-Golf is equipped with about 129 kg of aluminum, the Nissan Leaf 171 kg, while the luxury model Tesla S has about 661 kg of this metal [15][16][17].…”

Increase in number of transport vehicles, especially motor vehicles, has negative impact on environment. It refers to air pollution problem due to usage (combustion) of fossil fuels in motor vehicles. Agriculture activities, factories, industry and many other activities additionally contributes to air pollution. Greenhouse gas emission is main cause of global warming and air pollution, and mainly occurs due to industry and transport. In many countries, the adoption of legislation gives priority to the use of electric vehicles due to lower emissions compared to conventionally powered vehicles (diesel or gasoline engines). In this way, goals have been set in the European Union and regulations have been passed which, among other things, require a certain percentage of motor vehicle recycling at the end of their service life. The Directive 2000/53/EC of the European Parliament and of the Council regulates waste management in the vehicle sector. Due to the increased number of electric vehicles, which participate in the transport of goods and people, the paper partially analyzes the problem related to the adaptation of existing recycling centers (for classic vehicles), for the needs of recycling electric vehicles and their specific parts and equipment (such as magnets and electric motors).

During lithium-ion battery packing, joining between battery cases and tabs is challenging for manufacturers due to dissimilar materials of the battery case and the tab, as well as their thicknesses. Laser welding, which has proven to produce a good weld with high productivity and low electrical resistance, is introduced to weld these materials. The weld was conducted with nanosecond-pulsed fiber laser and the effect of laser powers on mechanical and electrical properties as well as microstructure of the joint is investigated. The weld bead at the low laser power exhibited several blowholes on the surface, while the formation of voids including centerline and root cavities was observed through the cross-section. Moreover, the phenomenon of upward penetration (UP) was observed in all laser powers and recoil pressure which was generated by metal evaporation was supposed to cause the formation of an upward flow of the lower material. A hardness test was performed on both horizontal and vertical directions through the fusion zone. Additionally, the increase of upward penetration (UP) resulted in higher strength and lower electrical resistance of the weld.
