By brazing there can be assembled piece...

The aim of this study was to compare the mechanical strength of different joints made by conventional brazing, TIG and laser welding with and without filling material. Five standardized joining configurations of orthodontic wire in spring hard quality were used: round, cross, 3 mm length, 9 mm length and 7 mm to orthodontic band. The joints were made by five different methods: brazing, tungsten...

In many industrial sectors, for example, aerospace, automotive and high-performance electronic industries, there is a significant need to join dissimilar materials. the case of medium-strength aluminum alloys, joints are commonly manufactured using Al-Si brazing fillers with melting temperature 575 °C. comparison high-strength alloys exhibit lower temperatures. Therefore, joining possibilities ...

Brazing fillers for joining applications are essential manufacturing and designing advanced materials. Several types of brazing have been developed in recent decades to join similar or different engineering Important parts automotive aircraft components, including steel, often joined by brazing. In addition, ceramic components microwave devices circuits with a high level integration microelectr...

Abstract Even though the buildup rate of laser powder bed fusion processes (LPBF) has steadily increased in recent years by using more and powerful systems, production large-volume parts is still extremely cost-intensive. Joining an additively manufactured complex part to a high-volume made conventional material promising technology enhance economics. Today, constructors have select most econom...

In the present work, a reliable TZM/graphite heterogeneous joint was prepared by vacuum brazing with Ti-35Ni alloy. The influence of temperature on interfacial microstructure, shear strength, and fracture characteristics joints were analyzed. formation mechanism also investigated in detail. TiC layer formed graphite during process, characterized SEM TEM analysis. microstructure brazed at 1200 °...
