Effect of heat input on the microstructure and mechanical properties of gas tungsten arc welded AISI 304 stainless steel joints
Subodh Kumar,A. S. Shahi +1 more
TL;DR: In this article, the effect of heat input on the microstructure and mechanical properties of gas tungsten arc welded 304 stainless steel (SS) joints was studied and the results indicated that the joints made using low heat input exhibited higher ultimate tensile strength than those welded with medium and high heat input.
Journal ArticleDOI
Selective laser melting of Ti6Al4V alloy: Process parameters, defects and post-treatments
Anil Kumar Singla,Mainak Banerjee,Aman Sharma,Jagtar Singh,Anuj Bansal,Munish Kumar Gupta,Navneet Khanna,A. S. Shahi,Deepak Kumar Goyal +8 more
TL;DR: In this paper, a critical review of noteworthy contributions in terms of SLM process parameters, defects and various post processing techniques considered by various researchers is aimed for critical review, which can clearly facilitate in developing a better scientific understanding of SLMed Ti6Al4V alloy.
Journal ArticleDOI
Modelling of the effects of welding conditions on dilution of stainless steel claddings produced by gas metal arc welding procedures
A. S. Shahi,Sunil Pandey +1 more
TL;DR: In this paper, the effects of various gas metal arc welding (GMAW) and universal GMAW process parameters on dilution in single layer stainless steel cladding of low carbon structural steel plates were analyzed.
Journal ArticleDOI
Metallurgical, wear and fatigue performance of Inconel 625 weld claddings
Sandeep Singh Sandhu,A. S. Shahi +1 more
TL;DR: In this paper, Inconel 625 claddings with low base metal dilution possessed better wear resistance as compared to those with high levels of dilution, which resulted in narrowing of the fusion boundary zone.
Journal ArticleDOI
Studies on metallurgical and impact toughness behavior of variably sensitized weld metal and heat affected zone of AISI 304L welds
Subodh Kumar,A. S. Shahi +1 more
TL;DR: In this article, the influence of sensitization on the metallurgical and impact toughness behavior of different gas tungsten arc AISI 304L welds has been investigated, where each weld has been characterized individually to understand the role of welding conditions on the carbide precipitation behavior which influences its impact toughness performance.
