Latest Patents
One of Yansong Zhang's latest patents is titled "Resistance welding with minimized weld expulsion." This invention involves a system designed to form a weld nugget in a metal workpiece. The system includes a power supply, actuator, electrodes, and a controller. The actuator delivers a variable electrode force to the workpiece based on a force command. The controller executes a method by transmitting a welding current command to the power supply, which outputs a welding current to the electrodes. The controller also transmits the force command to the actuator to apply the variable electrode force at a first force level. This force increases from a second force level immediately after a first duration to minimize weld expulsion. The second force level begins at a specific point in the dynamic resistance profile where the dynamic resistance value of the workpiece decreases at a threshold rate during the formation of the weld nugget.
Another notable patent is the "Method and apparatus for inspecting adhesive quality." This invention inspects the quality of adhesive material used for joining work surfaces during a weld-bonding process. A pair of workpieces are partially bonded by a layer of adhesive material, and the dynamic displacement of one or both electrodes is measured throughout the resistance welding process. This measurement helps determine the relative moisture content of the adhesive. A control action is executed when the dynamic displacement exceeds a stored threshold value. The apparatus includes a welding device with electrodes for providing clamping force and electrical current necessary for forming the welded joint, along with a sensor for measuring dynamic displacement.
