This research work was mainly concerned to investigate the effect of bonding temperature on the weldability of CoCrNi MEA with SUS 304 stainless steel. Shear test and nano hardness measurements were used to evaluate the mechanical performance of the welded joints. The formation of IMCs intensified along with the bond interface when samples were treated at low bonding temperature (i.e., 925 °C) which badly affected the joint’s shear strength. Reduction in IMCs formation transpired as the bonding ...

This paper explicates the joining of AA 6061/TiO2 composites by the friction stir welding (FSW) process. FSW experiments were conducted as per the three factors, three-level, central composite ivy– face-centered design method. Mathematical relationships between the FSW process parameters, namely tool geometry, welding speed, and tool rotational speed, and the output responses such as hardness, yield strength, and ultimate tensile strength were established using response surface methodology. Adeq...

The dynamic behaviors of weld pool and fusion hole are mutually coupled in tungsten inert gas (TIG) welding with reserved gap. This simulation has important significance for revealing the effect of fusion hole on weld pool and in enriching the knowledge of TIG welding process with gap. A combined heat distribution model that is adaptive to the free surface deformation of weld pool was established in the article. The interface of the fusion hole was tracked by using volume of fluid (VOF) method. ...

Cold metal transfer (CMT)–based wire-arc additive manufacturing (WAAM) is increasingly popular for the production of large and complex metallic components due to its high deposition rate, low heat input, and excellent material efficiency. The accurate prediction of the bead geometry is of great importance to enhance the stability of the process and its dimensional accuracy. Besides the wire feed speed (WFS) and travel speed (TS), the interlayer temperature is another key factor in determining th...
This document provides guidance and recommendations for exposure scenarios, risk management measures and to identify operational conditions under which metals, alloys and metallic articles and mixtures may be safely welded regarding welding fumes and gases exposure. It will be made available in all EU languages and Turkish. Considering the emission of fumes when welding, brazing or cutting of metals, it is recommended to arrange risk management measures through applying general information and g...

Microstructural and fatigue behavior of Inconel 718 weldments performed using gas tungsten arc welding process (GTAW) were studied. Ti and Nb segregation tends to form brittle phases (Laves, NbC and TiC), which were identified in the interdendritic region of the weld metal (WM). The heat generated to weld Inconel 718 produced a microstructural transformation of the γ´´ (Ni3Nb), decreasing the microhardness in comparison to the base metal (BM). The welded joints were heat treated by a solubilizat...

In the present work, the influence of current pulsation on microstructural morphology and mechanical properties of micro-plasma arc welded of 0.7-mm thick Alloy 718 is investigated. The pulsation of current improves the solidification morphology as compared to continuous mode. The effect of peak current, duty cycle, and pulse frequency on cooling rate, weld morphology, and mechanical properties are reported herein. The calculated solidification parameters from the 3D finite element-based heat tr...

Residual stress and deformation in a welded joint will significantly reduce its service life, and thus the analysis and regulation of residual stresses are very important. In this paper, a SYSWELD software was used to numerically simulate the temperature field, residual stress field, and the welding deformation during welding with and without a Cu interlayer. Thermocouples were used to measure the thermal cycle curves, and X-ray diffraction (XRD) was used to measure the residual stresses of the ...
