Visual inspection using laser vision sensor was proposed for fast and economic inspection and was verified experimentally. Welding is one of the most important manufacturing processes for automotive and electronics industries as well as heavy industries. The weld zone influences the reliability of the products. There are two kinds of weld inspection tests, destructive and nondestructive test. Even though the destructive test is much more reliable, the product should be destroyed, and hence the nondestructive test such as ultrasonic or Xray test was used to overcome this problem. However, these tests are not used for real time inspection.
