Sažetak
Welding is a crucial manufacturing process used in various industries, and it involves heating two or more metal parts to their melting point and then joining them together. The process of welding is complex, and the resulting microstructure and mechanical properties of the metal depend on various factors such as temperature, heating rate, cooling rate, and the type of metal being welded. Temperature is one of the most critical factors that influence the welding process, as it directly affects the microstructure and mechanical properties of the metal. Understanding the temperature fields in welding is essential for optimizing the process and improving the quality and performance of welded products. This research focuses on analyzing the temperature field distribution during arc welding, which is a common welding technique used in various industries. The objective of this study was to conduct a detailed analysis of three different types of temperature fields and develop a user-friendly Python program to calculate and display the temperature field distribution for each type of analysis. The three types of temperature fields analyzed in this study were for moving point heat source for half infinite body, moving line heat source for thin plates, and instant surface heat source. The Python program developed in this research provides an accessible tool for welders and engineers to better understand and control the welding process. The program calculates and displays the temperature field distribution in the form of interactive 2D and 3D graphs, where the temperature is plotted against length, width, and depth coordinates, as well as the velocity of the moving heat source. The program also calculates several key parameters from the temperature fields, including the temperature cycle, cooling rate, cooling time, maximum temperature, and the width of the heat-affected zone. The ability to control the welding process can lead to improved quality and performance of welded products, making this research a valuable addition to the field of welding engineering.
