Abstract
The invention provides a method and apparatus for on-line, real-time imaging and inspecting a seam weld on a moving tube in a conventional tube forming environment. The apparatus is in a compact container sealed from workplace contaminants. A planar light source directs a steady plane of light by using mirrors, through an aperture in the container and onto the tube seam at a 45.degree. angle relative to the tube axis, forming a light pattern on the moving tube. A camera in the container images the light, again at 45.degree. relative to the tube axis, and said image is displayed remotely on a conventional video monitor. An operator interprets the light pattern image and adjusts the tube forming apparatus accordingly.
