“…Although Kaewsakul et al [ 50 ] and Ibrahim et al [ 51 ] use different filler metal and they do not use the term “heat input” or “linear energy”, the key dependencies of bead physical properties on the GMAW technological parameters are similar to the conclusions drawn by the authors of the current study. The value of depth of penetration rises along with the length of the weld bead in both wires and stabilizes after 30–40 mm of bead length, which was expected.…”

Wear of the working surfaces of machinery parts is a phenomenon that cannot be fully countered, only postponed. Among surface lifecycle elongation techniques, hardfacing is one which is most often used in heavy load applications. Hardfaced coating can be applied using different welding approaches or thermal spraying technologies, which differ when it comes to weld bead dimensional precision, layer thickness, process efficiency and material. In this study the authors examine the geometrical behavior and hardness properties of two distinctive chromium-based Gas Metal Arc Welding (GMAW) cored wires. The stringer beads are applied numerically with five levels of linear energy, being a resultant of typical values of welding speed and wire feed, ranging between 250 mm/s to 1250 mm/s (welding speed) and 2 m/min to 10 m/min (wire feed). The samples were cut, etched and measured using a digital microscope and Vickers indenter, additionally the chemical composition was also examined. Hardness was measured at five points in each cutout, giving 40 measurements per sample. The values were analyzed using an ANOVA test as a statistical background in order to emphasize the divergent behavior of the cored wires. It appeared that, despite having less chromium in its chemical composition, wire DO*351 exhibits higher hardness values; however, DO*332 tends to have a more stable geometry across all of the heat input levels.

Material seringkali mengalami kerusakan atau retak yang diakibatkan oleh proses pengelasan, salah satunya berada di bawah lapisan pelindung material. Retak tersebut dapat diperiksa dengan metode Eddy Current Testing. Penelitian ini bertujuan untuk menganalisis sensitivitas dari Eddy Current Testing (ECT) dengan menggunakan variasi dimensi retak pada sambungan las tee joint material aluminium 5083. Penelitian ini menggunakan lima buah test piece material aluminium 5083 dengan masing-masing material berkuran 200 mm x 50 mm x 10 mm. Tiap material tersebut disambungkan dengan cara dilas. Retak buatan dibuat dengan menggunakan Electrical Discharge Machining (EDM) dengan variasi panjang dan kedalaman retak dengan 4 retak tiap test piece. Variasi panjang retak yang digunakan yaitu: 5.0 mm, 7.0 mm, 9.0 mm, dan 15.0 mm. Untuk variasi kedalaman retak yang digunakan yaitu: 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm dan 2.5 mm. Dengan menggunakan pengaturan parameter pengujian sebagai berikut.

“…The research [3] stated that the welding parameters in MIG welding majorly influence the surface texture, size, and shape of the weld bead, depth of penetration, quality, cost, and productivity. Work in [4] investigated the penetration level of the MIG welding parameter on three variables or parameters: current, voltage, and welding speed. When the welding current and voltage are increased, the depth of penetration is increased.…”

Mild steel has a wide range of uses such as in the construction field, automotive field, machinery industry, cookware, and pipeline. Metal Inert Gas (MIG) welding act as an assembly method of mild steel. Corrosion level is a common problem that occurs in MIG welding on mild steel. In this study, the suitable welding parameters such as voltage, number of passes, and method of welding were chosen in the experimental testing and the experimental testing was planned by using the Design of Experiment (DoE) as part of Taguchi method. The welded mild steel specimens were evaluated using a corrosion test. The data analysis was done by using Taguchi method. For the parameter to be the optimum welding parameter, the corrosion level was as low as possible. In this case, the S/N ratio smaller is better common interest is chosen. By using the Minitab 18 software, the S/N ratio was calculated. Hence from the result, the optimum parameter is 9V voltage, three passes and the welding method was circle push.
