据爱迪生焊接技术研究所的专家说,在检验大功率激光焊接质量方面,使用三个传感器比使用一个传感器好。他们发现,光学传感器、声学传感器和荷电粒子传感器都可单独用来检验焊缝,并可达到适中的精度。但是如果把这三种传感器融合起来使用,则可大大提高检验精度。 被称为“融合传感器”的这种多重测量技术适用于任何大功率“锁眼”激光焊接过程。汽车工业和航空航天工业正在调查这种多重测 According to experts at the Edison Welding Technology Institute, using three sensors is better than using one sensor in testing high-power laser welding quality. They found that optical sensors, acoustic sensors and charged particle sensors can be used alone to inspect welds and achieve moderate accuracy. However, if these three sensors are used together, the inspection accuracy can be greatly improved. This multiple measurement technology, known as a “converged sensor,” is suitable for any high-power “keyhole” laser welding process. The automotive industry and the aerospace industry are investigating such multiple tests
