Name one method to check for weld quality.

Visual inspection is a fundamental method used to assess weld quality because it allows the inspector to readily evaluate the weld surface for obvious defects such as cracks, lack of fusion, and incomplete penetration. This non-destructive testing method enables inspectors to quickly identify issues that may be visible to the naked eye, making it an accessible and efficient way of ensuring that welds meet quality standards.

While other methods, like ultrasonic testing, magnetic particle inspection, and X-ray inspection, are more advanced and can detect flaws within the material or weld that are not visible externally, visual inspection is often the first step in quality assessment. It not only helps in identifying surface defects but also provides an initial gauge of overall workmanship and adherence to welding specifications.

Because visual inspection requires minimal equipment and can be performed on-site, it is universally applicable across various welding applications, making it an essential skill for welders and inspectors alike.
