Parametric Investigation of Induced Oscillation on ARC Welding

Abstract

Welding is one of the important processes in mechanical engineering. In engineering sector, welding is a common phenomenon. Now-a-days, production time is an important factor in industrial sector because every industries is very competitive with each other. At the same time, maintaining quality of the product is necessary. For maintaining quality of joining process, there must be some changes in regular welding process. Normally, regular welding consumes lots of time. According to the research in welding process, it has been found that oscillation can improve mechanical properties of the joining section. However, welding joint quality varies with different ranges of parameters in different conditions. This study has been performed to analyze those ranges of parameters in some selected conditions. Here are some input parameters like vibration amplitude, vibration frequency, welding speed and electrode angle are selected to analyze the variation in welded joint. For analyzing the results, output parameters – hardness, bending strength, deposition rate and dilution are calculated. It has been found that if all input parameters are kept in a selected range then output parameters – hardness, bending strength, deposition rate and dilution increase than regular case. Therefore, it can be seen that welding process assisted by oscillation increases production rate as well as quality in high welding speed. After all, oscillation affects all of the major mechanical properties, which gives strength to the joining section in a welding process.
