Abstract
A tamping tine (5) for a tamping machine consists of a tine shaft (8) and, positioned at the lower end thereof, a tine pad (9) having a pad bottom edge (10) spaced from the tine shaft (8). The tine pad (9) has pad side surfaces (11), spaced from one another in the direction of the pad bottom edge (10) and extending perpendicularly to the same, each of which connect a pad front side (12) to a pad rear side of the tine pad (9). Hardened metal plates (14) for increasing the abrasion resistance are fastened to the tine pad (9). The hardened metal plates (14) situated side by side along the pad bottom edge (10) form a common boundary line (15) both on the pad front side (12) as well as on the pad rear side. Armoring (17) in the shape of a build-up welding, standing out from a plane (16) of the pad front- or -rear side, is provided adjoining each boundary line (15).
