DEVELOPMENT OF A ZIGZAG WELDING SYSTEM THAT WILL INCREASE PENETRATION AND EFFICIENCY IN WELDING TECHNOLOGY

Abstract

There are many methods used for the part joining process in the manufacturing industry. Among these methods, welding is the most widely used one. Products with more than one component are assembled by welding. Welding increases the durability and reliability of products by creating strong and durable connections between the joined parts. At the same time, welding simplifies the assembly process by reducing the number of parts and increases production efficiency. For these reasons, choosing the right welding method and applying it correctly is of great importance in industrial production processes. The MIG/MAG gas metal arc welding method is more widely used than other methods due to its mechanization, ease of welding in any position, etc. The quality control of joints made with this welding method is characterized by high penetration, low cost and high reliability at every stage of the welding process. Penetration refers to how deep the weld penetrates into the material and is a critical factor in the strength and durability of the weld joint. Sealing and durability of weld points are of great importance, especially in systems operating under high pressure or in sensitive parts. In this study, a zigzag welding apparatus was developed to eliminate the lack of penetration in gas welding technology. Cracks caused by lack of penetration at the welding point are prevented from preventing the part from fulfilling its purpose. When the results were examined; it was observed that there was insufficient melting and insufficient penetration in the visual controls of the products joined by the old welding method. The melting and penetration tests of the products joined with the developed zigzag welding apparatus were appropriate.  In this project, it is aimed to produce higher strength products by preventing these problems caused by lack of penetration.
