METHOD OF TWO-CHANNEL ULTRASONIC CONTROL OF WELDED CONNECTIONS WITH TECHNOLOGICAL POOR PENETRATION OF JOINT PARTS

FIELD: physics. ^ SUBSTANCE: using direct and inclined ultrasonic converters simultaneous scanning of across welded joint at pitch smaller than ultrasonic beam diameter is used. Echo signal propagation time through first and second channel is recorded. Total sequence of two-dimensional control zone...
