Abstract: Welding electrodes, methods, and vehicles are provided. The welding electrodes include a body that includes a weld face on a distal end of the body configured to contact a workpiece and apply an electrical current thereto. The body has a maximum diameter of 13 millimeters or less. The welding electrode includes an insulative material covering at least a portion of the body, the insulative material configured to mitigate current shunting upon contact between the insulative material and a workpiece of a workpiece stack-up while using the welding electrode to resistance weld the workpiece stack-up.
