Introduction

Sang Hyun Koo is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of welding inspection technology, holding a total of nine patents. His work focuses on enhancing the quality and reliability of welding processes, particularly in the context of lithium secondary batteries.

Latest Patents

One of his latest inventions is a welding quality inspection device. This apparatus is designed to inspect the welding state in a welded portion for electronic or mechanical coupling in lithium secondary batteries. It includes a measuring unit that obtains data to derive a resistance value of the welded portion by allowing a resistance measuring probe to contact it. The controller communicates with the measuring unit to determine the resistance value and assess whether weak welding has occurred by comparing it with a threshold resistance value.

Another significant patent is the welding failure inspection method. This method involves a threshold resistance setting step, where the resistance of a welded portion of a sample group is measured to derive a threshold resistance value. The subsequent resistance measuring step assesses the resistance value of the welded portion to be inspected. If this value exceeds the threshold, it is determined as weak welding. This method demonstrates excellent detection power for identifying welding defects.
