Risk Assessment for Welding and Cutting Processes Based on Fuzzy FMEA

Undoubtedly, risk management is considered the most important mission of the safety management system in industries. Risk is always associated with uncertainty. Therefore, one should be careful to perform risk assessment calculations based on principles that cover the uncertainties. One of the most important methods in this field uses risk calculations based on fuzzy logic that could provide an appropriate response to estimate the probable risk of incidents. This descriptive research aims to establish an optimal method for the risk assessment of the welding and cutting processes. This paper addresses the risk assessment based on a literature review, considering the fuzzy FMEA in the welding and inspection industry. The findings show that the most significant risks include “cutting by oxygen and gas, explosion and fire, damage and injuries to people and equipment/ cutting by gas – gas cylinder leakage, fire, explosion and body injuries”. The research results contribute to improving the risk assessment system
