Abstract

A production method for manufacturing a hairpin coil includes positioning a plurality of hairpin-like conductor elements on a coil support such that conductor end portions of conductor elements to be connected, which protrude from the coil support, are arranged adjacent to one another as conductor end portion pairs, securing the relative position of the conductor end portions of a conductor end portion pair, and simultaneously welding the respective conductor end portions of a plurality of conductor end portion pairs by friction welding, by a friction surface of a welding tool being simultaneously moved in a frictional manner along the plurality of conductor end portion pairs.
