摘要:
The invention relates to a method for remelting and refilling a defect (7) in a surface (19) of a substrate (4), wherein the defect (7) is remelted and wherein a hollow (28) is produced and wherein the hollow (28) that has been produced is refilled, and also to a component having a remelted region (25) and a solder region (31) thereover. In particular, a nickel- or cobalt-based substrate (4) is remelted by a laser remelting method, and subsequently the hollow (28) that is produced is refilled by a laser application method, in particular by soldering.

The present invention relates to a method for controlling a processing operation of a workpiece by means of a Reinforcement Learning (RL) agent unit, comprising the steps of: (a) observing an interaction zone in the workpiece by means of at least one radiation sensor to generate at least one sensor signal s t , wherein the workpiece is processed using an actuator having an initial actuator value a t ; (b) determining a basis function Φ(s t ) from the set of sensor signals s t ; (c) determining a reward function r t giving the probability of good results of the processing operation; (d) choosing a next actuator value a t+1 on the basis of a policy π depending on the reward function r t and the basis function Φ(s t ); and (e) repeating the steps (a) to (d) for further time points to perform a RL controlled processing operation.
摘要:
A battery module and methods for bonding a cell terminal of a battery to an interconnect member are provided. The battery module includes a battery cell having a cell terminal, and an exothermal reactive layer having first and second sides. The first side is disposed adjacent to the cell terminal. The module further includes an interconnect member disposed adjacent to the second side of the exothermal reactive layer. The exothermal reactive layer is ignited to form a bonding joint between the interconnect member and the cell terminal in response to a laser beam contacting at least a portion of the exothermal reactive layer.
