Latest Patents
One of Tenhaven's latest patents is for a resistance-weldable composite. This invention focuses on three-layer composites with a plastic core that is uniformly enriched with a specific percentage of ferrosilicon. This unique composition allows the composites to be securely joined to each other and to sheets of metal through resistance welding. The property is applicable to composites with either a viscously elastic or an impact-resistant core.
Another significant patent involves an apparatus for laser beam welding the longitudinal edges of a can. This invention utilizes laser beam welding for the mass production of welded shells for sheet metal cans. The design includes a guide system that ensures precise alignment of pieces to the welding machine, which consists of an X-rail, a guide bar, and spring-loaded jaws of a caterpillar tractor. This method produces a smooth welded seam on the inner side of the can shell by welding from both the inside and outside using a laser beam.
