ABSTRACT:
A method of welding a noble metal tip to a spark plug center electrode comprises the steps of placing a plurality of spark plug center electrodes into a plurality of carriers so that each carrier carries one spark plug center electrode, one by one moving each carrier into a weld station, lifting the one spark plug center electrode carried in the carrier located in the weld station out of the carrier into a weld position, clamping the one spark plug center into the weld position with a single clamp located in the weld station, and welding the noble metal tip to the one spark plug center electrode, wherein the single clamp eliminates clamp-to-clamp process variations.
