Metallography of microwelds is a complex process requiring long sample preparation time and extra care. A diamond-bladed microtome similar to the type used for slotting of production parts was adapted for metallography of laser welds of one mil wire. Sample preparation and analysis of the welds can be completed in approximately 15 to 20 min as opposed to the minimum of 3 hr required by the standard metallographic technique of mounting, grinding, and polishing. Surfaces of the metals produced by microtoming prior to etching are superior and have less deformed metal than surfaces produced by the standard metallographic techniques. The metallography of microwelds by microtoming resulted in improved surfaces in less time.
