In Robotic Gas Metal Arc Welding process, the welding parameters controlled by the welder (travel speed of the welding torch, wire feed speed, current, voltage, wire diameter, etc.) should be considered to obtain a desired welding quality. To design an appropriate welding model for the used equipment, the effects of each parameter should be studied by carrying out an adequate number of experiments. The welding process is described by analyzing the experimental data to define the relationships between the welding parameters and process variables. Various regressional models can be suggested to establish the analytical relationships. In this study, the relationship between bead geometry and voltage, current, travel speed and wire feed speed is established by using a specific computer program developed for this purpose.

Assessment of hand-type hammer drill bits under percussive loading Demir, Osman Koray; Çalışkan, Mehmet; Department of Mechanical Engineering (2007) The task of a drill bit in percussive drilling is to transport the initial kinetic energy of the hammer to the workpiece in terms of stress waves. The efficiency of this transportation and the stresses that the drill bit is exposed to during the process is dependent on the nature of the stress waves. In hand-type hammer drilling, changing dimensions of the bit means changing conditions for the propagation and interaction of the stress waves. In this study, using finite element method, wave propagation and i...
Investigation of wear behavior of aged and non-aged SiC-reinforced AlSi7Mg2 metal matrix composites in dry sliding conditions ÇELİK, YAHYA HIŞMAN; Demir, Mehmet Emin; KILIÇKAP, EROL; Kalkanlı, Ali (Springer Science and Business Media LLC, 2020-01-01) Metal matrix composites (MMCs) with their splendid mechanical properties have been specifically designed for use in fields such as aerospace and aviation. The presence of hard ceramic particles in MMC increases the hardness of the matrix product and decreases its coefficient of friction. Therefore, the wear resistance is improved. Moreover, the mechanical properties of these composite materials can be improved by applying heat treatments. In this study, AlSi7Mg2 MMCs with 15 wt% SiC reinforcement were produ...
Analysis of heat treatment effect on springback in v-bending Sarıkaya, Onur Turgay; Darendeliler, Haluk; Department of Mechanical Engineering (2008) Aluminum based alloys have wide area of usage in automotive and defense industry and bending processes are frequently applied during production. One of the most important design criteria of bending processes is springback, which can be basically defined as elastic recovery of the part during unloading. To overcome this problem, heat treatment is generally applied to the workpiece material to refine tensile properties. In this study, the effect of heat treatment on springback characteristics of aluminum stud...
Analysis of roll-forging process Karacaovalı, Hakan; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2005) Roll-forging is a metal forming process and mainly used for preform forging of long parts prior to press or hammer forging in the industry. Variable cross sections through the length of billet can be obtained by roll-forging to acquire an adequate distribution of material to the next forging stages. In the design of process and dies used in roll-forging, there are some empirical techniques in literature. However these techniques only provide approximate reduction ratio and elongation during the process and ...
Modeling of particle filled resin impregnation in compression resin transfer molding Şaş, Hatice Sinem; Erdal Erdoğmuş, Merve; Department of Mechanical Engineering (2010) Compression Resin Transfer Molding (CRTM) is an advanced liquid molding process for producing continuous fiber-reinforced composite parts in relatively large dimensions and with high fiber volume fractions. This thesis investigates this process for the purpose of producing continuous fiber reinforced composites with particle fillers. In many composites, fillers are used within the resin for various reasons such as cost reduction and improvement of properties. However, the presence of fillers in a process in...
