Patent number: 9676061Abstract: A method of fabricating a precoated steel plate is provided. The method includes coating a steel plate by dipping the steel plate in a molten bath to obtain a precoat upon the steel plate. The precoat consists of an intermetallic alloy layer and a metal alloy layer, the intermetallic alloy layer is topped by the metal alloy layer. On at least one face of the plate, the metal alloy layer is removed in an area at a periphery of the plate using a laser beam, while at least part of the intermetallic alloy layer is left in the area. The step of removing includes measuring a characteristic of the laser or an area where the metal alloy area is to be removed to obtain a measured value, comparing the measured value with a reference value and stopping a removal operation to leave the at least part of the intermetallic alloy in place as function of the comparing step. Additional methods are also provided.Type: GrantFiled: September 18, 2015Date of Patent: June 13, 2017Assignee: ARCELORMITTAL FRANCEInventors: Jean-Francois Canourgues, Aurelien Pic, Pascal Verrier, Rene Vierstraete, Wolfram Ehling, Bernd Thommes

Patent number: 9579744Abstract: A system for forming a weld nugget in a metal work piece includes a power supply, actuator, electrodes, and controller. The actuator delivers a variable electrode force to the work piece in response to a force command. The controller executes a method by transmitting a welding current command to the power supply to cause the power supply to output a welding current to the electrodes. The controller transmits the force command to the actuator to apply the variable electrode force, via the electrodes, to the work piece at a first force level. The variable electrode force increases from a second force level immediately upon conclusion of a first duration to minimize weld expulsion. The second force level commences at a point in time in the dynamic resistance profile at which a dynamic resistance value of the work piece decreases at a threshold rate during formation of the weld nugget.Type: GrantFiled: July 30, 2013Date of Patent: February 28, 2017Assignee: GM Global Technology Operations LLCInventors: Yansong Zhang, Guanlong Chen, Pei-Chung Wang, Yang-Yang Zhao, Xinmin Lai
