Operando X‐Ray Tomoscopy of Laser Beam Welding
Advanced ScienceThe phenomena occurring in a weld seam during advancement of a laser beam over a metallic component are still under dispute. The occurrence and evolution of porosity and the occasional blowout of melt need to be understood.

Correlation of keyhole dynamics and pore formation
, 2015 Imperfections like pores occurring due to high process dynamics during laser deep penetration welding reduce the weld quality and the strength of welded joints. It is assumed that keyhole instabilities are responsible for the high process dynamics.

Interaction Mechanism of Arc, Keyhole, and Weld Pool in Keyhole Plasma Arc Welding: A Review
The Keyhole Plasma Arc Welding (KPAW) process utilizes arc plasma highly constricted by a water-cooled cupper nozzle to produce great arc pressure for opening a keyhole in the weld pool, achieving full penetration to the thick plate.

Transport Phenomena and Keyhole Dynamics in Pulsed Laser Welding
, 2006 Numerical and experimental studies were conducted to investigate the heat transfer, fluid flow, and keyhole dynamics during a pulsed keyhole laser welding. A comprehensive mathematical model has been developed. In the model, the continuum formulation was

REAL-TIME MODEL PREDICTIVE CONTROL OF QUASI-KEYHOLE PIPE WELDING
, 2010 Quasi-keyhole, including plasma keyhole and double-sided welding, is a novel approach proposed to operate the keyhole arc welding process. It can result in a high quality weld, but also raise higher demand of the operator.

Physical Layer Security for Keyhole-based NOMA Downlink Systems with a Multi-antenna Eavesdropper
Journal of Telecommunications and Information TechnologyThis paper investigates the physical layer security of downlink nonorthogonal multiple access (NOMA) systems operating over a degenerate keyhole channel in the presence of a multi-antenna eavesdropper. We propose a joint antenna selection framework with
