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: 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.

Abstract: A robotic system for forming a moldable workpiece is provided. The robotic system includes a robot, an end effector, an adjustment module, and a control module. The robot is configured to pass the workpiece through a machine. The end effector is configured to be attached to the robot and configured to grasp and release the workpiece. The end effector is adjustable to a plurality of different configurations. The adjustment module is configured to determine a change in the workpiece from (a) a first form of the workpiece prior to the passing of the workpiece through the machine to (b) a second form of the workpiece after passing of the workpiece through the machine. The control module is configured to adjust a present configuration of the end effector to a second configuration based on the change in the workpiece from (a) the first form to (b) the second form.

Abstract: A flexible shelving unit includes a support frame having at least one vertical guide rack, the guide rack including an elongated slot. The shelf unit is supported by the guide rack. The shelf unit includes a shelf plate framed by a front reinforcement portion and by at least one side reinforcement portion. The shelf unit when in a release position is moved to selected upward and downward locations by vertical displacement of at least one locating pin connected to and extending from the at least one side reinforcement portion which is positioned and sliding within the elongated slot. A flat end face of the at least one side reinforcement portion directly contacts a plate face of the at least one vertical guide rack with the at least one side reinforcement portion and the shelf plate in a horizontal position to frictionally retain the shelf unit in the horizontal position.

Abstract: A method for healing surface irregularities in a weld joint includes generating a healing energy beam by a focused energy device, where the healing energy beam includes a predefined energy density. The method also includes scanning the healing energy beam along at least a portion of a periphery of the weld joint, where the weld joint includes at least an upper layer and a lower layer. The method also includes melting less than half a thickness of the upper layer of the weld joint. The predefined energy density of the healing energy beam is based on the thickness of the upper layer of the weld joint.
