When visually inspecting a finished weld, which factor should be assessed?

• A. Alignment and symmetry
• B. Excess weld metal height
• C. Electrical stickout
• D. Base metal hardness

Answer: (B)

When visually inspecting a finished weld, the assessment of excess weld metal height is crucial. This factor directly impacts the integrity and performance of the weld. An excessive height can lead to issues such as stress concentrations, which may cause the weld to fail under load or lead to crack propagation during service.

Additionally, measuring the weld's profile helps ensure that it meets the specified design and engineering standards, which are often outlined in welding procedure specifications (WPS) or applicable codes. Ensuring that the weld metal is within the acceptable height limits can help maintain the overall quality of the weld and ensure proper functionality in its application.

While alignment and symmetry, electrical stickout, and base metal hardness are important aspects in their own contexts, they do not directly relate to the visual inspection of the finished weld in terms of its adherence to functional and safety requirements. Thus, excess weld metal height is the most critical factor to assess during a visual inspection.
