A Statistical Review of Hydrogen Effects on the Fatigue and Fracture Behavior of Steel
ABSTRACT This study conducts a statistical re‐analysis of experimental data from the literature to assess the influence of hydrogen on key mechanical properties, including the medium‐/high‐cycle fatigue strength and the threshold value of the stress intensity factor range.

Investigation of a ceramic metal matrix composite functional surface layer manufactured using gas tungsten arc welding [PDF]
Wear resistant surfaces with high toughness and impact resistant properties are to be created to improve the life cycle cost of brake discs for trains. A potential solution to this industrial problem is to use an arc cladding process.

This study investigates the influence of laser power and welding speed on the quality of 304L stainless steel laser welds using numerical and experimental approaches. Results indicate that optimal parameters (4 kW, 3 m/min) enhance penetration while minimizing the heat‐affected zone, providing insights for industrial laser welding optimization ...

Numerical simulation and experimental validation of arc welding of DMR-249A steel
The thermo-mechanical attributes of DMR-249A steel weld joints manufactured by shielded metal arc welding (SMAW) and activated gas tungsten arc welding (A-GTAW) processes were studied using Finite Element Model (FEM) simulation. The thermal gradients and
