Method for defect free keyhole plasma arc welding [PDF]
, 1993 A plasma arc welding process for welding metal of increased thickness with one pass includes operating the plasma arc welding apparatus at a selected plasma gas flow rate, travel speed and arc current, to form a weld having a penetration ratio to weld ...

steel research international, EarlyView.In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can

Corrosion Behavior of Additively Manufactured Steels: A Comprehensive Review
steel research international, EarlyView.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 ...
