Analysis of Product Defects in Stay Horn Parts during the Welding Process Using Fault Tree Analysis (FTA) and Failure Mode and Effects Analysis (FMEA)

Abstract

The company in this study is an automotive company that produces, among other things, stay horn parts. The issue faced by the company is that the defect rate in stay horn parts exceeds the standard, with a defect rate of 2.06%, while the company's standard is set at 1%. This study aims to identify the highest cause of defects, determine the Risk Priority Number (RPN), and provide improvement suggestions to reduce the defect rate to meet the company's established standards. The methods used for this research are Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA).
