Post-joining thermal characteristics and repair integrity of carbon fiber-reinforced thermoplastic composites during ultrasonic reconsolidation at 20 kHz by Balaji Ragupathi, Lena Burger, Frank Balle

“…Temperature, a characteristic variable, is a key factor influencing the quality of joints in ultrasonic welding of thermoplastic composites. In this study, instead of measuring temperature during the joining process, the focus was on post-joining analysis on temperature at various hold times and holding forces. …”

Effect of SiC Addition on Microhardness and Relative Density during Selective Laser Melting of 316L Stainless Steel by Raid Mohammed Hadi, Ziad Aeyad Taha

“…The utilization of 316L stainless steel has been very common in marine, automotive, architectural, and biomedical applications due to its adequate corrosion resistance to cracks after the completion of welding process. However, there has been ongoing attempts to investigate the potential enhancement in the strength and durability of 316L stainless steel by reinforcing it with silicon carbide (SiC). …”

Experimental Study on Mechanical Performance of U-Shaped Steel-Encased Concrete Composite Beam-Girder Joints by Zhangqi Hu, Ran He, Yukui Wang, Weirong Lv, Jingchao Li

“…This paper proposes a novel U-shaped steel-encased concrete composite beam-girder joint (referred to herein as the novel composite beam-girder joint), in which the U-shaped beams at two sides (L and R) are inserted into a shaped sleeve, and the U-shaped girder and two U-shaped beams are connected by the shaped sleeve through welding. Compared with the traditional beam-girder joints, the novel composite beam-girder joints take advantage of easy construction, light weight, and short construction period. …”

Study on Interaction Mechanism of Natural Gas Pipe-Landslide System Reinforced by Micropile Groups Based on Model Test by Wei Guan, Honggang Wu, Daoyong Wu, Lin Tang, Hong Wei

“…The bending deformation of the perforated pipe micropile is large at the 1/4 position of the pile top from the pile bottom, and the deformation of the screw micropile near the sliding surface is serious. The pipeline welding port is the weak position of the pipeline; after the failure of the pile, the pipeline interface is first cracked, along the interface position along the two ends of the tear, and finally completely broken. …”
