What does assessing metal fatigue help prevent during the repair process?

Assessing metal fatigue is crucial during the repair process because it helps identify signs of wear and distress in the metal components that could lead to structural failure over time. Understanding the condition of the metal ensures that any underlying issues are addressed before repairs are made. This proactive approach is vital in preventing future structural problems that could compromise the safety and integrity of the vehicle. If metal fatigue is overlooked, it could result in the repaired area failing or experiencing deterioration more quickly than expected, leading to serious safety concerns. Hence, assessing metal fatigue directly contributes to mitigating future structural issues.
