Segregation Effect on Solidification Cracking in Spot Welding of the 6XXX Aluminum

Andrés RAMIREZ, Jonathan GRACIANO-URIBE, Diego HINCAPIE ZULUGA & Edwar TORREZ LOPEZ
Solidification cracking is a critical phenomenon, especially in the welding of AA6XXX, due these alloys present a wider freezing temperature range. The amount of liquid at the end of the solidification is a dominant factor in promoting or reducing the number of cracks. This paper proposes to assess the effect of the heat input in controlling the cracking during the spot welding in AA6061-T6. Four deposit conditions, made with GTAW, were assessed, in which the...

A Computational Analysis of Different Geometric Ratios at the Input of a Secondary Fluid that Affects the Efficiency of a Subsonic Air-Air Ejector

Jhon Fredy HINCAPIE-MONTOYA, Jorge Andres SIERRA-DEL-RIO, Edwar Andres TORRES-LOPEZ & Diego Andres HINCAPIE-ZULUAGA
For this study, the computational fluid dynamics (CFD) technique was used to investigate the combined effects of different geometric parameter relationships; inclination angle variation of the secondary fluid inlet, different lengths of the mixing chamber, and different separation values between the nozzle outlet and the input of the mixing chamber, in an air-air ejector used in a subsonic regime. As a working fluid, the air was used as an ideal gas and its viscosity was...
