A Study on the Corrosion Behavior in Sea Water of Welds Aluminum Alloy by Shielded Metal Arc Welding, Friction Stir Welding and Gas Tungsten Arc Welding

International Journal of Electrochemical Science, 2015
Three types of welds aluminum alloy 6061 were prepared using shielded metal arc welding (SMAW), friction stir welding (FSW) and gas tungsten arc welding (GTAW). In addition for the first time borax powder was used with GTAW in weld region to increase the

Review on Fatigue of Additive Manufactured Metallic Alloys: Microstructure, Performance, Enhancement, and Assessment Methods

Advanced Materials, Volume 36, Issue 17, April 25, 2024.
Additive manufactured metals have excellent mechanical properties, but their fatigue resistance is an exception. This article reviews the processes attributes, hierarchical microstructure, fatigue performance, and evaluation methods. The fatigue failure mechanisms of printed metals were summarized, and the competition between trans‐scale ...

Influence of surface treatment on metal dusting resistance of welds

Materials and Corrosion, Volume 75, Issue 3, Page 371-385, March 2024.
Fe contaminations enhanced metal dusting pit formation on brushed welds of Ni‐based alloys. The best performance of the welds was achieved by grinding, this is attributed to the deformation of the sub‐surface zone. Additional protection by on‐site slurry aluminization was successfully demonstrated.

On dissimilar metal welding of AISI4140 and AISI410 by GTAW

IOP Conference Series: Materials Science and Engineering, 2017
This paper presents the results of metallurgical and mechanical examinations of Gas Tungsten Arc Welding of dissimilar steels AISI4140 and AISI410. Two different filler materials viz., ERNiCr3 and SS410 were used. The various properties of the weldments made using the fillers were compared to select the most appropriate one to get the sound joint.

Visualisation of alternating shielding gas flow in GTAW [PDF]

Materials & Design, 2016
The alternating shielding gas technique is a method of achieving transient arc characteristics during arc welding; however the complex flow that occurs through its use has not been investigated previously. A schlieren system was used to image density gradients that arise when alternating argon and helium shield gases, under varying flow parameters ...

Analysis and optimization of the automated TIG welding process parameters on SS304 incorporating Taguchi optimization technique

The Journal of Engineering, Volume 2024, Issue 3, March 2024.
The present research work focused on optimizing the input parameters of automated TIG welding process of SS304 metal. Since SS304 possess high inter‐granular toughness and corrosion resistance with increased lifespan in the pressure vessel and automobile component fabrication sector, its hardness and tensile strength response are undertaken for ...
