Soil opener with compound carbide protection

Abstract

An agricultural tillage tool is configured to be advanced along a field in a forward direction. The tool broadly includes a base tool structure and a pre-brazed wear tablet. The base tool structure is configured to engage the ground while being advanced. The wear tablet includes a metallic wear plate and a steel backing plate, with the plates being brazed to one another. The metallic wear plate includes a wear material and the backing plate includes a backing plate material, with the wear material having a hardness greater than the backing plate material. The backing plate is laser welded to the base tool structure so as to fix the pre-brazed wear tablet to the base tool structure, with the metallic wear element being located ahead of the backing plate relative to the forward direction.
