Tensile Properties of Ferrite-austenitic Welded Joint
Very often, in order to optimized welded constructions, some of their parts are made of heterogeneous steels. For example, microalloyed steels are in use for cars chassis making and high alloyed steels for different constructions making. From that reason, it’s not rare to find welded joints between ferrite microalloyed and austenitic highalloyed steels. As a rule, these joints are welded by usi...
متن کاملThe Effect of Heat Input on the Weld Metal Toughness of Surface Welded Joint
The welding heat input has a great influence on the weldments properties. This paper describes the influence of welding heat input on the weld metal toughness of high-carbon steel surface welded joint. The steel is surfaced with self-shielded wire, with three different heat inputs (6.5; 10.5 and 16 kJ/cm). Total impact energy, as well as crack initiation and crack propagation energies, are esti...
متن کاملEvaluation Model of Aluminum Alloy Welded Joint Low-Cycle Fatigue Data Based on Information Entropy
An evaluation model of aluminum alloy welded joint low-cycle fatigue data based on information entropy is proposed. Through calculating and analyzing the information entropy of decision attributes, quantitative contribution of stress concentration, plate thickness, and loading mode to the fatigue destruction are researched. Results reveal that the total information entropy of the fatigue data b...
متن کاملAssessment of Qt Steel's Welded Joint Toughness Based on Real and Simulated Specimens
Conventional assessment of welded joint impact toughness, as defined in relevant standards for welding procedure qualification is based on testing of real specimens taken from base metal, weld metal, and heat affected zone. Here particularly, testing of heat affected zone may become unreliable, mainly due to the welded joint configuration and placement of initial notch. In addition, from genera...
