A track bushing for an endless track of a track-type machine includes a cylindrical tubular shape having a first end and a second end and a longitudinal axis. The track bushing further includes a first end bearing surface that is adjacent to the first end and a second end bearing surface that is adjacent to the second end. A circumferential groove is formed in at least one of the first end bearing surface and the second end bearing surface. The circumferential groove has a depth along the longitudinal axis. An abrasion and corrosion resistant material is arc welded within the circumferential groove to the bushing at a weld joint.
