Ultrasonic inspection method for lead-acid battery terminal posts

摘要

An ultrasonic testing method to evaluate the structural integrity of lead-acid batteries terminal posts including the steps of transmitting ultrasonic waves from a transducer through the body of the lead-acid battery posts, detecting the internal defects in the terminal posts by a reflected echo from the internal defect, and deciding to reject or to accept a lead-acid battery by comparing and analyzing, through hardware and software, the transmitted and reflected ultrasonic waves of the bad terminal posts against the reference of transmitted and reflected ultrasonic signal of a good terminal post. The internal defects detected by this method are pores, flaws, and cracks.
