Visual inspection criteria

Visual inspection criteria define which surface conditions, shape and dimensional deviations are considered acceptable. They help with the visual control of workpieces.

How It Works Physically and Chemically

Visual inspection criteria are about eyeballing surfaces, shapes, and dimensions. They set the acceptable tolerances for irregularities and deviations.

Why It Matters in Welding & the Risks

Using the criteria wrong or going past them can leave visual defects like cracks, sagging, or uneven surfaces. That can mess up how the part works and how it looks.

Shop Practice & What to Do

Before you start a visual inspection, make sure the criteria are clear. Use tools like magnifiers or rulers to check things closely. Make sure every dimension and shape falls within the set tolerances.
