Title: Innovations of Manohar Das in Resistance Spot Welding
Introduction
Manohar Das is an accomplished inventor based in Rochester Hills, MI (US), known for his significant contributions to the field of resistance spot welding. With a total of three patents to his name, Das has developed innovative systems and methods that enhance the efficiency and effectiveness of welding processes.
Latest Patents
One of his latest patents is titled "System and method for performing resistance spot welding." This invention features a probeless energy delivery controller that includes a power supply module generating a first current and a power delivery module that produces a second current from the first. The current is delivered to electrodes that have weld pieces interposed between them. As the current flows, the resistance and temperature of the weld pieces increase, leading to their melting. The system also incorporates a voltage control module that estimates the resistance of the weld pieces and determines a phase angle for setting the voltage output based on the estimated resistance and a power profile.
Another notable patent is the "Method and apparatus for resistance spot welding." This invention describes a welding method where multiple stacks of metal sheets are clamped together at a welding site. A pair of electrode caps supplies welding current to spot weld the sheets in a series of operations. The electrode caps apply a closing force to clamp the sheets together, along with a predetermined interjoint force that progressively increases throughout the production run.
Career Highlights
Throughout his career, Manohar Das has worked with prominent companies such as DaimlerChrysler Corporation and Chrysler Group LLC. His experience in these organizations has allowed him to refine his skills and contribute to advancements in welding technology.
