Abstract: A laser welding system for joining a first workpiece to a second workpiece includes a laser welder configured to emit a laser beam at a power to form a weld to join the first workpiece and the second workpiece at a weld location. The laser welding system includes a plasma protection fixture coupled to a surface of at least the first workpiece. The plasma protection fixture defines an opening configured to receive the laser beam. The opening has a perimeter that surrounds and is spaced apart from the weld. The plasma protection fixture has a height above the surface of at least the first workpiece about the perimeter of the opening that is defined based on the power of the laser beam.

Abstract: Robotic systems and methods are provided with an end effector having lockable compliance. A robotic system for manipulating a workpiece includes an arm having a pair of sections connected by a joint assembly, with a lock disposed in the joint assembly. A gripper is connected on the arm and is configured to alternately grip and release the workpiece. A controller operates the lock to alternately lock and unlock the joint assembly. The gripper holds the workpiece during a deformation of the workpiece, while the controller may unlock the lock to allow movement of the joint assembly to relieve forces on the arm arising during a deformation of the workpiece.

Abstract: A welding electrode includes a weld face that has a convex base weld face surface and a plurality of ringed ridges that are radially spaced apart on the base weld face surface and surround a central weld face axis. The plurality of ringed ridges including an innermost ringed ridge and an outermost ringed ridge. The innermost ringed ridge is located closest to the central weld face axis and rises above a central portion of the base weld face surface, and the outermost ringed ridge is located farthest from the central weld face axis and rises above an outer peripheral portion of the base weld face surface. At least one of the plurality of ringed ridges is a discontinuous ringed ridge.

Abstract: A system for evaluating a rigidity of an angle bracket includes a test system having a first test fixture and a second test fixture. The system includes an angle bracket coupon including a first wall, a second wall coupled to the first wall at a bend to define an angle between the first wall and the second wall, and at least one three dimensional feature defined at the bend that extends between the first wall and the second wall. The angle bracket coupon is to be coupled to at least one of the first test fixture and the second test fixture to evaluate the rigidity of the angle bracket.

Abstract: A rechargeable energy storage system includes a first plurality of cells arranged in a first horizontal cell stack. Each of the first plurality of cells includes a first diameter, a first end and a second end spaced from the first end by a first distance defining a first cell axis. A second plurality of cells is arranged in a second horizontal cell stack. Each of the second plurality of cells includes a second diameter, a first end portion, and a second end portion that is spaced from the first end portion a second distance defining a second cell axis that is substantially colinear with the first cell axis. A cross beam member is disposed between the first horizontal cell stack and the second horizontal cell stack. The cross beam member absorbs heat from each of the first plurality of cells and the second plurality of cells.

Abstract: Aspects of the disclosure include air flow systems configured to regulate air flow when laser welding to improve laser weld quality. An exemplary air flow system can include a primary inlet coupled to an air source and one or more secondary inlets coupled to the primary inlet. At least one of the one or more secondary inlets can include an internal valve. Each internal valve is actuatable between a fully open state, a fully closed state, and an intermediate state. The air flow system can further include an outlet coupled to each of the one or more secondary inlets downstream of the internal valve and a controller configured to adjust a position of each internal valve. The controller is configured to adjust the position of each internal valve based on an air flow mapping to increase an average air flow velocity along a laser beam of a welding laser.

Abstract: Systems and methods for bending a material to a target resultant bending parameter using a bend forming tool are disclosed. The systems and methods receive values for parameters of properties of the material and of a bending process to be performed by the bend forming tool, creating or retrieving a calibration curve relating input bending parameter and resultant bending parameter based on the values from a database of calibration curves, determining a first springback compensated input bending parameter based on the target resultant bending parameter using the calibration curve, inputting the first springback compensated input bending parameter to the bend forming tool, and in a first step of bending the material, bending the material to the first springback compensated input bending parameter by applying the bending process using the bend forming tool.
