Abstract
A trowel blade assembly for use on a power trowel includes multiple blades, each having a top surface and a bottom surface, and a blade bar attached to the top surface by a laser weld. The blade is manufactured from unfinished sheet metal of trowel blade quality by a method that uses a laser for both cutting and welding the sheet metal. With the blade bar stabilized on the top surface of the blade, the laser weld is applied along the bottom surface of the blade in a single continuous weld, or as multiple non-continuous weld segments, in a path that is parallel to a longitudinal center of the blade bar.
