Abstract

In this study, research on the use of the External Magnetic Field method – Tungsten Inert Gas was done to determine the effect of welding arc compression on the quality of AISI 304 thin plate weld. The welding process was performed using autogenous welds. In this study, an external magnetic field was generated by placing a magnetic solenoid around the TIG welding torch. Enabling this electromagnetic field is done dynamically using a microcontroller. Welding parameters used are welding current 100; 105; 110 A and welding speed 1.6; 1.8; 2.05 mm/s. The results of this study showed that EMF-TIG welding can produce a more uniform bead width along the weld line with a standard deviation of 0.08 compared with conventional TIG welding of 0.12. Increased welding speed of  2.05 mm/s causes no effect on the addition of an external magnetic field to the width of the weld bead. The current parameters are 105 A with a speed of 1.6; 1.8; 2.05 mm/s resulted in compression of the top bead width by 0.87; 0.61; 0.1 mm. The welding parameters with a current of 105 A and welding speed of 1.6 mm/s have a larger upper bead compression effect of 0.84 mm compared to 110 A currents of 0.38 mm. Moreover, the D/W ratio obtained under an external magnetic field was higher than without magnetic.

Abstract

The concept of clean and renewable energy is currently a focus developed continuously. One of the abundant sources of clean and renewable energy is water. A water turbine is a mechanism to generate electrical energy by utilizing the water flow. Pico or nano hydro turbines produce electrical energy by taking advantage of the flow of water that rotates the shaft of the electric generator. This experimental study aims to analyze the effect of differences in the number of blades on a Horizontal axis drag-type Savonius turbine mounted of water flow in a vertical pipe. The variations of blades number used in the study are 3, 4, 6, 8, 10, and 12. The potential energy of the water is kept constant with a constant head of 2 meters. Four main parameters used as a benchmark for the performance of water turbines are rotor rotation, voltage, current and electrical power generated. The results showed that the rotor rotation, voltage, current, and generated electrical power decreased as the number of blades used increased. The water turbine of 3 blades produces the best performance compared to the other one. The magnitude of the rotor rotation, voltage, current, and electrical power generated is 846 rpm, 15.28 volts, 0.61 amperes, and 9.38 Watts, respectively.
