Abstract

Shield Metal Arc Welding (SMAW) welding in practice often faces challenges in the form of defects in the joints which damage the quality of the connection. One implementation of welding connections is the process of making a paddock. Poor welding can damage the paddock and harm its users. The research aims to determine the effect of welding speed and electrodes on the tensile strength, hardness and microstructure of ST-37 steel welded joints. The research used AWS E 7016 and AWS E 6013 electrodes with a current of 100 amperes and varying welding speeds of 0.2 cm/s, 0.3 cm/s and 0.4 cm/s. The highest tensile strength for the AWS E 7016 electrode was 460.32 MPa and the lowest for the AWS E 6013 electrode was 256.02 MPa. The highest hardness value on AWS E 7016 was 236.07 MPa and the lowest was on AWS E 6013, amounting to 176.86 MPa. The ferrite composition dominates the weld metal. Because ferrite is ductile and not too hard, it means that the weld metal area is ductile and the hardness is not too high.

Abstract

Electric folding bikes are a modern transportation solution that offers practicality and efficiency of storage space. Production alternatives are needed to reduce dependence on pipes and welding processes. One alternative production process is to use the metal casting method. This study aims to design and analyze the strength the design of the frame, pillion, and battery holder of the electric folding bicycle for the metal casting process. The material used is A356 aluminum. The design and simulation process is carried out using CAD and CAE software. The loading simulation was conducted under real load conditions with a load of 99,5 kg. Based on the results of simulation and analysis, the design of the frame, bonnet, and battery compartment of the best electric folding bicycle has a von Mises stress value of 61,21 MPa, displacement of 1,712 mm, mass of 4,6 kg, and safety factor of 4,5.
