Lecture
This lecture covers the fundamentals of soldering and brazing, including the role of fluxes and shielding gases. It explains the process steps involved in soldering and brazing, such as cleaning, positioning, heating, and cooling. The lecture also discusses the use of eutectic alloys in soldering, interfaces in solder joints, and high-temperature brazing. It delves into the challenges of brazing aluminum and its alloys, as well as the wetting and filling of joints in brazed or soldered assemblies. Additionally, it explores the use of fluxes, different types of flux compositions, and self-fluxing brazing alloys. The lecture concludes with examples of brazed hybrid metal-ceramic parts and soldering procedures like reflow soldering.
