Date Jul. 5, 1994.Method for hardfacing of parts of the edges of a chainsaw guide bar, where the chain is guided by a groove, where a wear-resistant alloy is applied in a molten state to parts of the edges (12,13) of a guide bar blank and solidified in nearly final configuration, comprising the steps of: making a guide bar blank (10) having edges located at greater distance from the groove bottom (18) along the sides (17) which are not to be hardfaced than in those parts (12,13) which are to be hardfaced, and applying a mold (15) with an extending plate (14) against the blank with the edge (23) of the plate in contact with the groove bottom (18), and filling the space between the wall (19) of the mold and the edges (12,13) of the blank with a paste (16) made from finely powderized hardfacing alloy and a liquid, and heating the paste (16) locally to melt the alloy.
