Title: Larisa Evgenievna Bogomolova and the Cold Butt-Welding Machine.

Introduction

Larisa Evgenievna Bogomolova is an inventor associated with Kyiv, Ukraine. Her recorded patent concerns a machine designed to cold butt-weld metal blanks, including aluminum and copper workpieces of various cross-sectional shapes.

Latest Patents

The available information lists one patent for Bogomolova: “Cold butt-welding machine.” The invention describes a machine with clamping devices and movable cutting blades that trim the ends of metal blanks before welding. The blades can shift in the direction of the upsetting force, allowing the machine to leave the amount of metal needed to form the weld.

The machine’s guide members support the clamping devices in a cantilever arrangement and allow them to be set at different angles in at least one vertical plane. This design accommodates blanks positioned in different spatial relationships and helps maintain axial alignment during clamping and upsetting. The machine can also weld blanks with at least one flat surface along their perimeter.

The patent describes potential uses in extending electric motor winding ends, coiling high-capacity power transformers, producing continuous wire, and welding multicore cables. The listed patent count is 1 patent.

Career Highlights

Bogomolova’s documented invention addresses practical challenges in cold butt welding, including workpiece alignment, end preparation, and the joining of blanks with varied shapes. The available information does not identify an employer, so no company affiliation is included.
