Arc characteristics of GTAW under high pressure

Sādhanā, 2019
The characteristics of GTA (gas tungsten arc) under high pressure has been studied in this paper to reveal the special arc phenomenon from the ambient pressure. A totally new hyperbaric GTAW experiment system has been built, including a hyperbaric environment simulator (0.1-3.5 MPa), an automatic GTAW machine with cooling, the moving equipment, a ...

Corrosion Behavior of Additively Manufactured Steels: A Comprehensive Review

steel research international, Volume 96, Issue 10, Page 51-79, October 2025.
This review explores the corrosion behavior of various steel types, including austenitic, martensitic, duplex, low‐alloy, and maraging steels, produced via additive manufacturing (AM). It discusses how AM impacts material properties, such as grain structure and the formation of defects like porosity, and highlights the importance of optimizing process ...
