Macrostructural and Mechanical Evaluation of Butt‐Welded AW‐6082 Aluminium Alloy Connections

ce/papers, Volume 9, Issue 2-3, Page 801-806, September 2026.
Abstract The welding of aluminium alloys significantly alters their mechanical behaviour, which directly affects the behaviour of structural aluminium connections and joints. This study focuses on butt‐welded connections made of EN AW‐6082‐T651 alloy, produced using pulsed MIG welding with both direct current (DC) and alternating current (AC), with ...

Mechanical Properties Characterization of Welded 3CR12 Stainless Steel

ITEGAM-JETIA
The use of metal inert gas (MIG) welding for joining metals frequently results in the change of the mechanical properties and the microstructure of the metal at the welded areas. This is due to the welding heat input and heat transfer.

Experimental Study of Imperfections in Longitudinally Welded AW‐5083‐H321 Aluminium Alloy Members

ce/papers, Volume 9, Issue 2-3, Page 766-771, September 2026.
Abstract Welding of aluminium alloys presents many challenges, the most notable being strength reduction in the heat‐affected zone and pronounced welding‐induced deformations. Consequently, longitudinally welded aluminium members have been poorly studied, with existing experimental data both sparse and largely outdated.

The institutional paradox of a substantivist conception of the economy in public policy: Insights from public procurement for solidarity economy in Ecuador

Annals of Public and Cooperative Economics, Volume 97, Issue 3, Page 871-900, September 2026.
Abstract Ecuador's 2008 Constitution advanced an ambitious substantive economic vision through Buen Vivir (Good Living), recognizing a plural economy which encompasses private, public and solidarity economy (SE) sectors. This paper aims to analyze public procurement programs in Ecuador, one of the flagship Buen Vivir policies for SE promotion.
