Groove angle and quenching medium in shielded metal arc welding of mild steel: Multi-criteria decision analysis, machine learning and energy absorption

Weld groove geometry and post-weld cooling regime are among the least systematically investigated factors influencing the performance of arc-welded joints, and even when they have been studied, the analysis has almost always been limited to a single optimisation criterion. This p...

Sustainable Machining in the Era of Industry 5.0: A Unified Review of Minimum Quantity Lubrication, Nanofluids, and Human-Centric Process Optimisation for Net-Zero Manufacturing

Conventional flood cooling remains the dominant lubrication strategy in machining workshops worldwide, despite more than three decades of documented evidence concerning its environmental and occupational health costs. A single production facility may consume thousands of litres o...
