Title: Charles Andrew Keskimaki: Innovator in Weld Detection Technology

Introduction

Charles Andrew Keskimaki is a notable inventor based in Plainsboro, NJ (US). He has made significant contributions to the field of weld detection technology, holding 2 patents that enhance the understanding and quality assurance of welding processes.

Latest Patents

Keskimaki's latest patents include a method and apparatus for distinguishing stress wave emissions from signals emanating from a weld. This innovative approach involves detecting signals during the post-weld period and counting excursions of the detected signal above a predetermined threshold. Simultaneously, an envelope of the signal is developed, and excursions above the threshold are also counted. A ratio of the signal excursion count to the envelope excursion count is formed, which is then compared to known ranges of ratio values to determine whether the detected signal is mechanical noise or a stress wave emission signal. Another patent focuses on determining the acceptability of a weld formed during an AC welding operation. This method detects stress wave emission signals during various phases of the welding process and compares the counts to predetermined ranges of values to assess weld quality.
