Damaged Part

Definition

The weld is not correctly made due to the use of a flawed workpiece.

Description

The weld is not properly made due to the workpiece not meeting specifications (examples: twisted, bent, scratched, torn, surface quality, surface coating, etc.).

Detection

Detection evidence may include:

• Cracks and Holes
• Expulsion/Burn Through
• Inconsistent Weld Quality
• Mislocated/Edge Weld
• Nonround Weld
• Poor Class A Appearance
• Sheet Metal Distortion
• Undersized Weld
• Part Inspection

Significance

Quality, Workplace Issues, Cost, Downtime, Maintenance, Throughput (cycle time; PPH), are all potentially affected by this condition. Special considerations are noted below:

Quality: Welding process may be correct but flawed workpieces result in nonconforming assemblies.
