A secondary battery includes an electrode assembly, a current collector coupled to the electrode assembly, a case accommodating the electrode assembly and the current collector, a cap plate coupled to the case, the cap plate sealing the electrode assembly and the current collector in the case, and a terminal plate connected to the current collector, the terminal plate being exposed through the cap plate, wherein the current collector is welded to at least one of the electrode assembly and the terminal plate by both a dual beam welding and a wobble welding.

An example system includes: a hand-held welding tool that is manually placed in a welding position, wherein the hand-held welding tool is configured to be activated to cause a contact tip or a welding heat source to automatically move from a first position and to second position during a welding operation, and wherein a welding arc is automatically and repeatedly turned off and on while the contact tip or the welding heat source moves from the first position to the second position to make a plurality of welds between the first position and the second position, wherein, as a travel speed decreases, a time period between each arc on time increases to make equally spaced welds.

A method for monitoring and/or controlling in a closed loop a laser welding process for welding together two workpieces of metallic material includes, during the laser welding process, scanning a melt pool and/or a melt bead using an optical coherence tomography (OCT) measurement beam in at least one line scan, determining an actual geometry of the melt pool and/or the melt bead based on the at least one line scan, and setting at least one welding parameter controlled in the closed loop based on a deviation of the actual geometry from a target geometry of the melt pool and/or the melt bead.

In various embodiments, workpieces are processed, e.g., via welding or cutting, while the shape and/or one or more other parameters of the laser processing beam are altered. The shape and/or one or more other parameters of the laser processing beam may be varied based on one or more characteristics of the workpiece.
