Abstract
A method for healing surface cracks 10, especially in metals, by scanning a high-energy, diffused, pulsed electron-beam past a crack 10 in a slowly moving specimen object 12. The crack 10 moves laterally with respect to the beam so that the beam pattern 14 is a sawtooth pattern comprising a series of overlapping circles 22, each comprising one pulse of diffused energy.
