Abstract: The sensitivity of contactless ultrasonic sensor is improved from 3.3% to 26% through acoustic, electric matching technique. Along two crest lines auto seam tracking is firstly realized with contactless ultrasonic sensing. The focused acoustic lens is designed with the best of care, the diameter with 0.5mm of sonic beam is achieved, Through software and hardware technique the horizontal precision of seam tracking with ultrasonic sensing is to 0.5mm and the vertical precision of that is to 0.2mm.

Key words: Arc welding, Contactless seam tracking, Ultrasonic sensor
