Weld Fatigue Scan

Weld Fatigue Scan is a diagnostic inspection used to detect microfractures, stress cracks, and fatigue in the welded joints of a trailer’s frame. For food trailers, this assessment is essential to ensure structural reliability under the constant stress of transportation, vibration, and the added weight of kitchen equipment. Scans are typically performed during scheduled maintenance, after extended travel, or when signs of structural strain—such as creaking, misalignment, or visible weld degradation—appear.

Use in Food Trailers

• Structural Integrity Checks Verify that the trailer’s frame and welds remain secure under frequent movement and operational loads.
• Early Damage Detection Discovers minor weld issues before they escalate into major structural failures or expensive repairs.
• Regulatory Compliance Supports adherence to Department of Transportation and local safety standards by documenting structural inspections.
• Improved Safety Reduces the risk of frame failure, ensuring a safer environment for operators and customers.
• Extended Equipment Lifespan Protects mounted systems such as plumbing, electrical, and appliances by maintaining a stable frame foundation.
• Resale Value Preservation Helps maintain market value by demonstrating consistent structural upkeep.

Vendor Tips

Conduct a weld fatigue scan at least once annually, or more often if your trailer is subject to frequent use or rough road conditions. Select a technician experienced with food trailers, as their specific layout and load distribution can affect stress points differently than standard trailers. Maintain detailed inspection and repair records to support permit applications, insurance claims, and future resale transactions.
