Diagnóstico de los factores microestructurales en el proceso de soldadura MIG/MAG que causan averías en los transformadores: estudio de caso. In: VII International Scientific Conference of Mechanical Engineering, 2012, Villa Clara. Anais... Villa Clara: 2012. p. 1-8.https://rigalileo.itegam.org.br/handle/123456789/1095The study examined microstructural factors in the MIG/MAG welding process of 3 mm and 4 mm industrial steel, leading to failures in 500 KVA power transformers. Charpy-V impact tests and microstructural analysis were conducted to correlate microstructure with impact toughness. Results revealed impurities in the weld pool, affecting weld quality and causing leaks of insulating oil.pdf.Soldagem MIG/MAGtransformadores de potênciamicroestruturatenacidade ao impactoanálise metalográficaArtigoEngenharia Mecânica
