Welds in sliding direction

Welds also experience wear in the sliding direction, especially from fine abrasive particles that wear down the welds in the gap between the two liner plates.

Small abrasive particles are concentrated to the groove between the liner plates, wearing away the welds faster than the wear plates.

A range of techniques have been developed to minimize this problem, and the general approach is to prevent sand from flowing easily into the groove.

Different welding patterns used to avoid wear along the weld.
