Abstract

GJS 400-15 ductile cast iron has excellent physical-chemical, mechanical-structural and manufacturability properties. However, it has notable limitations when it is subjected to welding operations. The objective of this work is the characterization of the welds made in GJS 400-15 ductile cast iron parts, specifically 6mm thick sheets, to determine their applicability based on the mechanical and microstructural properties obtained. For this, several welding procedures have been proposed, in which an Fe-Ni alloy is used as a filler material and SMAW and TIG welding techniques are combined with different heat treatments. The mechanical characterization tests have been based on tensile analysis and hardness determination. As for the micrographic analysis, it has been carried out through the micrographs of the thermally affected areas (base metal, interface and welding). TIG welding, in general terms, has been effective in the welding processes of nodular cast iron sheets despite its disadvantage in the results obtained compared to the SMAW technique. On the contrary, the advantages that the TIG welding technique presents in terms of execution time and more favorable cost open a way to the development, technical evolution and industrialization of the welding processes carried out using this last technique. It is hoped that the study will present a positive contribution to the technological development of welding processes and their industrial application to the manufacture, maintenance or repair of parts and products in which ductile iron is present and especially those formed by steel plates. small thickness.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Dyna, and although the journal is classified in the quartile Q4 (Agencia WoS (JCR)), its regional focus and specialization in Engineering, Multidisciplinary, give it significant recognition in a specific niche of scientific knowledge at an international level.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-07-16:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 5.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 5 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.
  • The number of mentions on the social network X (formerly Twitter): 2 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:
