“…This area as the local thermal cycle from heat input transfer produced the grain growth to become coarse grain. So the hardness value decreased [9,10,12] but some area in the HAZ had grain refinement such as aluminum, niobium, vanadium and titanium. The grains at HAZ are refined compared to grain size of base metal.…”

“…Mohanty et al investigated the neural modelling of the influence of welding parameters in arc welding processes to study the welding current, arc voltage and welding speed in different arc welding process which effected the bead geometry and heat affected zone [8]. Kim et al investigated a study on the quality improvement of robotic GMA welding process and reported the top-bead width [9]. Rajkumar [10] found that the shape of fusion zone depends upon a number of parameters such as gas flow rate, voltage, travel speed and wire feed rate.In HAZ the value of hardness was found highest but the hardness at weld metal (WM) was found minimum.…”

“…Contudo, é constante o desenvolvimento de técnicas de soldagem com o intuito de aprimorar este processo a fim de atingir o máximo de desempenho e, assim, aumentar a taxa de deposição possível de ser conseguida e/ou obter melhores propriedades mecânicas da junta soldada atrelado a esta alta capacidade de deposição. Neste contexto, é possível encontrar na literatura uma grande quantidade de trabalhos que abordam o emprego de diversas técnicas de soldagem no processo SAW, como a utilização de múltiplos arames [2][3][4][5][6], em configurações conhecidas como "twin-arc" ou "tandem-arc", o emprego …”

Em vista disso, neste trabalho foi realizada uma investigação quanto ao emprego da técnica de tecimento no processo SAW. Para tanto, foram realizados ensaios de soldagem com amplitudes de tecimento (triangular) entre 0 e 30 mm para três níveis diferentes de energia de soldagem e avaliadas a penetração, largura, reforço, área do reforço e da área fundida dos cordões de solda obtidos, além da estabilidade do processo. Como resultado, verificou-se que, além de perfeitamente viável, a aplicação da citada técnica no processo SAW resultou em maior eficiência de fusão no processo, sem, entretanto, acarretar em instabilidades no processo ou problemas relacionados à inclusão de escória.Palavras-chave: Oscilação transversal; SAW; Eficiência de fusão; Morfologia dos cordões. Evaluation of Oscillation Movement in Submerged Arc WeldingAbstract: Although very common in many welding processes, there is no reference in the industrial applications, nor in the specialized literature, to the use of transverse oscillation movement of the electrode in submerged arc welding. In view of this, in this work an investigation was made regarding the use of the weaving technique in the SAW process. Therefore, welding tests with amplitudes of weaving (triangular) between 0 and 30 mm were carried out for three different levels of welding energy and the penetration, width, reinforcement, reinforcement area and melt area of the weld beads obtained were evaluated, besides the stability of the process. As a result, it was found that, in addition to being perfectly feasible, the application of cited technique in the SAW resulted in higher process melt efficiency, without, however, process instabilities or problems related to the inclusion of slag.

IntroduçãoO emprego do processo de soldagem a arco submerso (SAW) na construção pesada como em estaleiros, mineradoras, siderúrgicas, fábricas de perfis e estruturas metálicas é algo recorrente. Isto se deve, sobretudo, a capacidade deste processo em atender a uma demanda comum destas empresas, que consiste na união de chapas de maior espessura.Uma característica marcante do processo SAW está no seu elevado rendimento de deposição e de fusão. Isto se deve, fundamentalmente, à inexistência de perdas de material por projeções ou respingos e à menor perda de calor para o meio, o que faz com que o processo aprese...

The efficient application of any welding process depends on the understanding of associated process parameters influence on the weld quality. The weld quality includes the weld bead dimensions, temperature distribution, metallurgical phases and the mechanical properties. A detailed review on the experimental and numerical approaches to understand the parametric influence of a single wire submerged arc welding (SAW) and multi-wire SAW processes on the final weld quality is reported in two parts. The first part deals with the experimental approaches which explain the parametric influence on the weld bead dimensions, metallurgical phases and the mechanical properties of the SAW weldment. Furthermore, the studies related to statistical modeling of the present welding process are also discussed. The second part deals with the numerical approaches which focus on the conduction based, and heat transfer and fluid flow analysis based studies in the present welding process. The present paper is the first part.
