Abstract

Pipe welding is widely used in industries with piping systems, including the oil, construction, and manufacturing industries. Several parameters, including the width of the weld bead, can determine the quality of good welding results. In this research, pipe welding was carried out automatically in the 5G position using GTAW (Gas Tungsten Arc Welding) without metal filler (Autogenous). Welding tests were carried out to determine the effect of weaving speed on the uniformity of weld bead width from 0° to 360° and the weld bead width of 316L Stainless Steel pipes with an inner diameter of 4 inches and a thickness of 4 mm using a zigzag (weaving) welding pattern. The welding method uses the Pulse Current Gas Arc Welding (PC-GTAW) method with a current of 137 A and a background current of 10 PPS (Pulse Per Current). Test samples were taken at 4 (four) welding points, namely 0°, 90°, 180° and 270° with a torch height of 2 mm to the test object. The test was carried out with 3 (three) variations of weaving speed, namely 0.150 mm/s, 0.155 mm/s, and 0.161 mm/s. The welding tool used is a prototype orbital pipe welding tool using the 5G method, which is then carried out by forming a test object. Weld bead width was measured using a digital microscope model Dino-Lite AM 4515ZT and DinoCapture 3.0 software. The bead width measurements show that the most consistent weld bead width uniformity occurs at a weaving speed of 0.155 mm/s. Meanwhile, the average weld bead width at a weaving speed of 0.150 is 10.26 mm; at a weaving speed of 0.155 mm/s, it is 10.44 mm; and at a weaving speed of 0.161 mm/s, the average weld bead width is 9.8 mm.

Abstract

Wire arc additive manufacturing (WAAM) is gaining popularity due to its ability to produce large metal parts quickly and efficiently. It produces less waste and has a more efficient production time than subtractive manufacturing. However, those capabilities come with unavoidable disadvantages, post-processing by machining becomes necessary to achieve the desired product dimension. Therefore, this research aimed to evaluate the bead geometry and utilization area of the WAAM-fabricated structure by varying the deposition current. The wall-structured specimens were fabricated using gas metal arc welding (GMAW) with motorized drivers for x, y, and z coordinates. The material used in this research was low carbon steel ER70S-6 filler metal with ASTM A36 low carbon steel substrate. The Varying parameter was deposition current with other related process parameters remaining constant. Material testing and characterization techniques included geometric measurement by profile projector plotted into a scattered diagram, and the cross section of the specimens were observed using a digital microscope. The experiment resulted in increased bead dimension in width and height along with increased deposition current. The largest bead dimension was achieved in 180A deposition current with average bead width and height was 6.84 mm and 1.6 mm respectively. The best deposition current was 160A, with highest area utilization of 81.43% and width uniformity.

Abstract

Additive manufacturing has become a focus of industry and research due to the many new developments in processes and systems. This is further strengthened by the trend of resource efficiency, as manufacturing processes towards additive manufacturing offer the possibility of producing close to the required size shape. Additive manufactured products can experience surface imperfections assessed in this study, namely the morphology profile or surface curvature (surface waviness) of the weld bead layer. Generally, surface curvature can be referred to as a "hump" caused by the welding process. To achieve the target of achieving products with relatively minimal surface waviness, experiments and analysis of the manufacturing process using GTAW additive welding on AA 6061 substrate material with ER 5356 filler were conducted. The experiments were carried out by first determining the process parameters and factors that affect the quality of the weld bead layer. The layers stacked in layers were measured for their width and height geometry, surface waviness tests were conducted, and analysis was carried out. The deposition rate or filler deposit, travel speed, and filler feed speed determine the level of surface waviness. In this study, high surface curvature occurred at a wire feeder speed (WFS) of 25 mm/s with a travel speed (TS) of 80 mm/min.

Abstract

Two stage refilled friction stir spot welding (TS-RFSSW) is a method to eliminate keyholes formed in the friction stir spot welding (FSSW). This study aims to investigate the effect of tool geometry on the tensile shear loads of joints produced by TS-RFSSW. Copper and aluminum AA110 sheets with a thickness of 0.42 mm were joined using the TS-RFSSW process. The tools used in the first stage have taper and triangular pins. In the second stage, pinless tools with 5 mm and 6 mm diameters were used to close the keyhole. Other process parameters used included a dwell time of 4 seconds, a plunge depth of 600 µm, and a tool tilt angle of 0⁰. The TS-RFSSW process successfully produced improved joint surfaces with minimal keyholes, resulting in increased tensile shear loads. The tool with a triangular pin produced joints with higher tensile shear loads due to more intensive material flow. On the other hand, increasing the diameter of the pinless tool for the second stage reduced the tensile shear loads of the joints. The maximum tensile shear load achieved was 292.78 ± 34.72 N using a triangular pin tool for the first stage and a 5 mm pinless tool for the second stage.

Abstract

Wire arc Additive Manufacturing (WAAM) is a technology capable of manufacturing large and complex components using aluminum alloys. This is due to its high deposition rate and efficient material utilization. However, WAAM faces several issues, particularly regarding process stability. In the WAAM process, especially when using Gas Metal Arc Welding (GMAW), stability is largely determined by controllable process parameters such as travel speed and arc length. This study aims to clarify how fusion stability, influenced by travel speed and arc length, affects the resulting deposit geometry and heat accumulation. The experimental method involved conducting a single-layer WAAM process using GMAW, with ER5356 filler (diameter 1 mm) and AA6061 substrate. During the single-layer WAAM GMAW process, the heat temperature and current were measured in real-time on the deposits. The results included minimum and maximum height and width measurements of the deposits produced. It was observed that increasing the travel speed reduced the current, thereby lowering the heat input. Heat accumulation, under fixed parameters of 80 A current, 16 V voltage, and varying travel speeds and arc lengths, fluctuated throughout the process. At an arc length of 6 mm, the single-layer deposit geometry exhibited humping, causing irregular widths and heights. Overall, both travel speed and arc length played significant roles in determining the maximum and minimum heights of the deposits.

Abstract

Welding the joints of pipes is often required for maintenance and repairs in industrial applications, where pipes are frequently used. A prototype of an orbital pipe welding machine was constructed, and its design, analysis, and construction were carried out. The goal of this endeavor was to improve the quality of the welding process as well as overall productivity. The design study was carried out with the assistance of the SolidWorks program, which allowed for the determination of the stress, strain, displacement, and factor of safety imposed on the gear section throughout the welding and pipe installation process. During pipe installation, the gear section experiences maximum stresses of 3.920e+12 MPa, 5.029e+05 MPa, and 2.239e+06 MPa, respectively. These stresses are a result of the pipe being installed. When the pipe is installed, the highest strain in the gear section is 1.802e+01%, 3.030e-06%, and 8.439e-06%, respectively. This strain happens when the pipe is installed. In addition, the maximum displacement in the gear section is 3.074e+09 mm, 3.215e+04 mm, and 6.312e-03 mm, respectively, when the pipe is mounted and the pipe is installed. With a value of 1.5, the analysis results demonstrated that the maximum stresses, strains, and displacements in the gear section during the welding process are sufficient to fulfill the requirements for the critical safety factor. This demonstrates that the orbital pipe welding equipment may be utilized to generate welds of superior quality while simultaneously enhancing both productivity and efficiency through its utilization.
