Method and arrangement for optical inspection of a weld seam |
摘要 |
In the welding together of sheet-metal blanks an image of a line pattern projected across the weld seam is captured by a camera and evaluated to inspect the weld seam. For improved inspection, a sidewards view of the weld seam is obtained, eg. by means of a prism, in addition to the view from above. This affords an improved and more accurate inspection of the weld seam.
