Abstract

Welding repairs are often carried out on directionally solidified components that nevertheless do not possess the desired crystallographic surface alignment, which reduces mechanical strength. The method provided selects the direction of travel depending on the crystallographically preferred direction of the substrate such that no more misorientations occur. A laser beam may be used for remelting.
