Introduction

Lawrence R. Lehman is a notable inventor based in Columbus, OH (US), recognized for his contributions to welding technology. With a total of 2 patents, he has made significant advancements in the field, particularly in conductive heat seam welding.

Latest Patents

Lehman’s latest patents include innovative methods for welding arrangements. One of his patents, titled "Conductive Heat Seam Welding," describes a welding arrangement that involves first and second parts to be welded. The edge portions of these parts are juxtaposed to form a weld zone. An electrically-conductive sheet with a higher melting temperature than that of the first and second parts is placed over the weld zone. A force application device applies a lateral compressive force to the weld zone, while first and second electrodes are placed in contact with the conductive sheet, which is resistively heated to conductively heat the weld zone.

Another patent, "Conductive Heat Resistance Seam Welding," outlines a similar welding arrangement. It consists of first and second parts with portions juxtaposed to form a weld zone. An electrically-conductive sheet with a higher melting temperature than that of both parts is placed over the weld zone. The first electrode contacts the conductive sheet material, while a second electrode is aligned with the first to heat the weld zone with electrical current. For the butt weld configuration, a second electrically conductive sheet is placed between the second electrode and the weld zone.
