“…8) Bridge girders. [2] performed Optimization of Submerged Arc Welding Parameters for Joining Disimilar Materials Using Taguchi Method and the author concluded that the decrease in the welding speed, decrease in welding current and the increase in welding speed up to limit will result in decrease in weld bead width. At last the author analyzed that the voltage is most important factor that affect hardness of the weld bead.…”

Welding is the process joining two or more similar or dissimilar metal by the application of heat or sometimes pressure. called submerged arc welding process. The main objective of this review paper is to study and understand the various components, equiptments used and the effect of process variables such as welding current, welding speed, electrode, electrode angle etc that direct influences the tensile strength, hardness, bead width, bead reinforcement, depth of penetration etc. Welding is a fabrication or sculptural process which sole purpose is to join the materials. In current era of technology without welding technique we will reach to a stone age. So welding is one of the most useful fabrication process and it is the backbone of industries like construction industries, railways industries, aircraft industries etc. SAW which is

“…A diferença entre a área de penetração e reforço está diretamente ligada ao fato de possuírem diferenças de entrada de calor nos parâmetros estudados. De acordo com o trabalho de Kumar e Gupta [27], diversos autores como Kannan e Murugan [28], Kumanan et al [29], Saluja e Moeed [30], Umrigar e Chaudhry [31] e Moshi et al [32] reforçam a afirmativa de que a corrente é a variável mais importante dentre os parâmetros de soldagem. Do mesmo modo, pode-se afirmar que a diferença do diâmetro do arame é um fator importante na influência desses resultados, pois afeta a corrente de soldagem que será utilizada.…”

Atrelado a isso, a soldagem de campo é complexa e muitas vezes onerosa. Um processo de fabricação alternativo para tubulações é o processo de formação de tubos com costura helicoidal. Este trabalho propõe estudar as características microestruturais e realizar uma avaliação mecânica destas soldas executadas em campo do aço ASTM A1018. Para alcançar o objetivo do trabalho foram utilizados dois tubos de aço fabricados com chapas de espessura de 12,5 mm e diâmetro nominal de 1200 mm, através do equipamento adaptado para a soldagem em campo pelo processo de soldagem por arco submerso. Após soldagem dos tubos, foram retiradas amostras destes para efetuar as análises de micrografia, macrografia, composição química, dobramento e dureza. A principal diferença apresentada entre as amostras foi o aumento da ferrita acicular e redução da ferrita primária de contorno de grão com o decréscimo do aporte térmico nas microestruturas formadas tanto na zona fundida como na ZTA como apresentado. Observou-se, ainda, mudanças na geometria dos cordões de solda. Por fim, identificou-se que o principal parâmetro que influência nas mudanças microestruturais apresentadas é a corrente de soldagem. Palavras-chave: Tubos helicoidais; Soldagem por arco submerso; Caracterização microestrutural e mecânica.Abstract: A problem commonly found in the production of tubes is related to transportation due its large dimensions. This fact, makes field welding a complex and often costly operation.. An alternative fabrication process for pipes is the process of forming tubes with helical welds. This work proposes to study the microstructural characteristics and perform a mechanical evaluation of these welds performed in field of ASTM A1018 steel tubes. In order to reach the aim, two steel tubes manufactured from sheets with a thickness of 12.5 mm and a nominal diameter of 1200 mm were welded by the process of submerged arc welding through the equipment adapted for field welding. Subsequently, samples were taken to perform characterization by microanalysis. Chemical composition, bending and hardness tests were also conducted. The main difference between the samples was the increase of the acicular ferrite and reduction of the primary ferrite of the grain boundary with the decrease of the thermal contribution in the microstructures formed in the molten zone as in the ZTA as presented. Also, changes in the geometry of the weld beads were observed. Finally, it was identified that the main parameter that influences the microstructural changes presented is the welding current.

This research addresses the escalating need for lightweight materials, such as aluminum and magnesium alloys, in the aerospace and automotive sectors. The study explores friction stir welding (FSW), a cost-efficient process known for producing high-quality joints in these materials. The experiment involved the welding of dissimilar aluminum alloys (AA5086-H111 to AA6061-T6) using a novel pin tool design with welding parameters such as holding time, pin tool length, tool spindle speed, and linear speed fine-tuned through a design of experiment (DOE) approach. A comparative analysis of two tool designs revealed that the newly introduced design substantially improved mechanical properties, particularly tensile strengths, by 18.2% relative to its predecessor. It is noteworthy that FSW joint efficiency is 83% when using a normal tool design in comparison with 92.2% when using a new tool design at similar FSW parameters. The new tool achieved the parameter values leading to the maximum tensile strength of 317 MPa with 3 mm thickness (Th), 25 s holding time (Tt), 0.1 mm dimension (L), 1600 rpm spindle speed (SS), and 30 mm/min feed velocity (Fr). In comparison, the normal tool achieved a maximum UTS of 285 MPa, 5 mm Th, 25 s Tt, 0.3 mm L, 800 rpm SS, and 90 mm/min Fr. The new tool design, with longitudinal and circular grooves, improves heat input for plastic deformation and alloy mixing during welding. Subsequent analysis of the joint’s microstructure and microhardness shows its similarity to the original alloys.
