CMOS camera checks automotive laser welds: To increase throughput and reliability of automotive parts, a machine-vision inspection system assesses weld-seam integrity

摘要

Before automobile doors or hoods can be pressed, they must be shaped into a specific form using a number of individual metal sheets or tubes known as "tailored" and "tubular" blanks. After these blanks are welded together, each individual weld must be rigorously checked before the metal can be pressed.
