investigation of the Joining Technology of frp az31b magnesium alloy by welding and riveting hybrid bonding method
Materials, 2019Co-Authors: Hongyang Wang, Liming LiuAbstract:A novel Joining Technology was applied to join Fiber Reinforced Polymer (FRP) and AZ31B Mg alloy, which combined the laser-arc welding source and riveting Joining methods. The design idea of the stepped rivet was proposed. The weld morphology, mechanical properties, microstructures of welds under two different rivet structures were investigated. FRP and AZ31B Mg could be joined successfully by the new hybrid Joining method when it used two different structural rivets. The maximum tensile shear load of the joint under stepped rivet of small size was only 800 N, while that of the joint under stepped rivet of the larger size could reach 1419 N, nearly 90% of that of FRP. There was no reaction between the FRP plate and AZ31B rivet. While the magnesium elements and aluminum elements diffused and reacted with other elements in the FRP plate/AZ31B plate interface.

a new laser Joining Technology for direct bonding of metals and plastics
Materials & Design, 2016Co-Authors: Y J Chen, T M Yue, Zhong Ning GuoAbstract:Abstract A direct laser Joining technique for bonding plastics to metals, namely laser-assisted metal and plastic (LAMP) Joining was developed about eight years ago. Notwithstanding the successes that have been obtained for LAMP, the inherent features of laser-induced bubbles in the joint remains a major concern. In this research, a new laser Joining Technology with the aid of ultrasonic vibration has been developed to bond plastics to metals with improved joint strength. Experiments have been conducted to join polyethylene terephthalate and titanium using this new Technology; preliminary results have been encouraging. With the aid of ultrasonic vibration, joint strength can be improved by as much as four times greater than that produced by the conventional LAMP process. This improvement is largely caused by the formation of a thicker chemically bonded metal-plastic interface, which was supported by the results of an XPS analysis conducted across the joint interface.

laserbonding instead of ultrasonic wire bonding an alternative Joining Technology for power applications
International Conference on Electronics Packaging, 2017Co-Authors: Josef Sedlmair, Benjamin Mehlmann, Alexander OlowinskyAbstract:Laserbonding is a newly developed Technology that combines the flexibility and robustness of classical ultrasonic wire-bonding with the advantages of laser welding as regards large connector cross-sections, low quality requirements to surf aces and clamping rigidity. Thanks to modern laser sources with high brilliance, near-infrared radiation can be used in oscillation welding Cu even in a keyhole fashion even though Cu is traditionally considered illsuited for such laser wavelengths. The process is most useful for connecting copper ribbons of 2 × 0, 2 mm size to Li battery cells of the 18650 type but can also be adapted for larger prismatic cells. Further development is geared towards connecting power semiconductors.

tube tube Joining Technology by using rotary swaging forming method
Journal of Materials Processing Technology, 2014Co-Authors: Qi ZhangAbstract:Abstract With the development of the manufacturing Technology, a challenge has been proposed on the Joining of difficult welding materials and the poor connection interface of materials. In this paper, rotary swaging Technology is utilized as a Joining by plastic deformation forming method to join tube/tube parts with different diameters. Experimental set-up of rotary swaging forming was designed and fabricated, in which the forging energy can be adjusted by changing the rotation speed of AC server motor. The rotary swaging model and tension testing model are established by using FE simulation software Forge 2D. The effects of forming parameters on the tension strength of the joined tubes and the Joining mechanism are investigated. The results show that a concave arc joint can be formed at the overlapping parts of the tubes. To obtain the high Joining strength, the distance from the end of the inner tube to the center of the hammer die need to exceed a certain value. The maximum strain and stress occur at the concave arc Joining region in which the thickness variation of the two joined tubes is small. To exam the Joining strength, the tension test was performed. The two tubes tend to slide out during tension process and the maximum stress occurs at the relative sliding region. The ratio on tensile load of the joined tubes to the maximum tensile load of the single tube can reach to 68% for the inner tube and 47% for the outer tube. Therefore, the Joining strength of the tube/tube parts, formed by using rotary swaging method, is enough high.
