Abstract

Friction welding is a welding technique that melts metal. Jointing of metals by utilizing the heat generated by friction between metal surfaces in which variations in the pressure distance are determined. The purpose of this study is to determine the strength of the welded joint after the welding process by using variations in the pressure distance of 3mm, 4mm, and 5mm. The material used in this research is carbon steel S45C shaft. Studies have shown that welding at the deepest compression distance produces a very strong welded joint, the greater the stress during the welding process, the stronger the joint in the welding. Welding with compression distances of 4mm and 5mm. and the impact price is higher compared to the 3mm pressing distance.

Abstract

Friction welding is a type of welding that connects two materials with the heat generated by the material itself so that it does not require additional materials. Heat can occur due to the presence of two objects rubbing against each other so that the material can melt and there is a connection due to forging process. The purpose of this study was to determine the impact strength of friction welding joints. The material used in this research is low carbon steel St.41 in the form of of a solid cylinder which has a diameter of 13mm. From the research that has been done, it is found that friction welding using 720 and 1000 rpm have better joint strength than using 450 rpm, which means that specimens with 720 and 1000 rpm have a higher amount of energy absorbed and impact values than specimens using 450 rpm.

Abstract

This research aims to design and simulate a Hebel-type lightweight brick cutting machine with a horizontal motion system to improve cutting efficiency and precision at the TACON Tangan Construction production house in Bangka Belitung. The development of this tool is based on the needs of small industry players to increase productivity and reduce production costs, because most of the cutting process is still done manually. The design uses the VDI 2222 method which includes the planning, concept development, technical design, and design completion stages. This machine works with an electric motor transmission system that drives the cutting wire through an eccentric shaft, resulting in horizontal reciprocating motion. Simulation results using SolidWorks show that the machine works stably, efficiently, and safely. The design considers aspects of ergonomics, safety, and ease of maintenance. Theoretically, this design can increase cutting effectiveness by up to 40% and support the productivity of lightweight brick manufacturing.
