“…Additionally, Dutra et al (2016) studied Inconel 625 coatings that was cladded by MIG/MAG pulsed + DC, Pulsed AC and CMT process with steel plate as the substrate material using 45 o welding position. The coating process was carried out starting from the bottom and moving upward.…”

“…The choice of shielding gas in welding of Inconel 625 with MIG/MAG is not too easy, because the short circuiting and spray transfer on MIG/MAG process has a large effect on the phenomenon of the welding, most especially the heat input. From Dutra et al (2016) research you will find out that on overlay welding with weaving bead using Inconel 625, CMT process require 25% helium in shielding gas compared to pulsed DC and pulsed AC which the wetting was sufficient with Ar +2.5%CO2. Baixo and Dutra (2011) state that pure argon works only on spray transfer mode.…”

“…In recent years, CMT has been one of the most significant improvements to the GMAW process, with good effects on process stability and HI control on the BM [69]. Strict electrical controls, such as current-voltage waveforms, with changes in the polarities and electromechanical control of the droplet detachments, are used in these techniques [70,71]. As a result, the auto industry has been working to improve the quality of joining parts by overcoming the limitations of the conventional GMAW process in recent years, leading to the development of pulsed arc technologies for the better joining of AHSS.…”

In recent years, the demand for advanced high-strength steel (AHSS) has increased to improve the durability and service life of steel structures. The development of these steels involves innovative processing technologies and steel alloy design concepts. Joining these steels is predominantly conducted by following fusion welding techniques, such as gas metal arc welding, tungsten inert gas welding, and laser welding. These fusion welding techniques often lead to a loss of mechanical properties due to the weld thermal cycles in the heat-affected zone (HAZ) and the deposited filler wire chemistry. This review paper elucidates the current studies on the state-of-the-art of weldability on AHSS, with ultimate strength levels above 800 MPa. The effects of alloy designs on the HAZ softening, microstructure evolution, and the mechanical properties of the weld joints corresponding to different welding techniques and filler wire chemistry are discussed. More specifically, the fusion welding techniques used for the welding of AHSS were summarized. This review article gives an insight into the issues while selecting a particular fusion welding technique for the welding of AHSS.

“…Tal estabilidade da poça fundida, segundo estes autores, também favorece a soldagem em maiores velocidades. A liga IN625, no entanto, apresenta dificuldades associadas à molhabilidade utilizando processo CMT [5] o que em se tratando de manufatura aditiva, a princípio, pode ser benéfico do ponto de vista de obtenção de componentes estruturais de forma complexa.…”

Resumo A manufatura aditiva é um processo utilizado na construção de peças com complexidade geométrica e no reparo de componentes mecânicos com alto valor agregado sendo portanto atrativa quando se utilizam materiais de elevado custo haja vista a menor necessidade de subtração de material. Nesse processo de deposição de multicamadas seguindo um modelo digital são produzidas estruturas mecânicas 3D. O sucesso de cada procedimento depende dos parâmetros de processamento, que incluem técnica de deposição, parâmetros, liga a ser depositada e condições da deposição. Controlar o efeito destes parâmetros nas propriedades é determinante para beneficiar o curto tempo de desenvolvimento do projeto na produção de peças. Neste contexto, diversos estudos têm sido desenvolvidos avaliando o efeito das multicamadas nas características dos componentes. Este trabalho vem contribuir para este tema após o processamento de multicamadas de uma liga a base de Ni (IN625) pelo processo MIG/MAG - CMT (Cold Metal Transfer). Amostras (paredes) de 15 cm de altura foram obtidas pela sobreposição de cordões e caracterizadas na condição como-depositada e após tratamento térmico de homogeneização. A influência da sobreposição das camadas na microestrutura e propriedades mecânicas foi avaliada por meio de medidas de dureza e ensaios de tração. O efeito dos múltiplos ciclos térmicos na microestrutura e nas propriedades mecânicas antes e após tratamento térmico foi também avaliado. Resultados mostraram que o tratamento térmico minimizou as heterogeneidades da microestrutura com multicamadas promovendo um aumento na resistência mecânica, porém, com queda da ductilidade quando comparado à amostra na condição como processada. A análise da região da fratura dos corpos-de-prova tracionados contribuiu para um melhor entendimento do efeito da deposição de multicamadas e posterior tratamento térmico.
