i used a hardface welding inside our dredgepump housing to avoid wear on pump inner surface. however, after several months, the crack line occured on the surface of the unwelded. Could this things happen because of the hardfacing weld?

Comeback with the materials involved, the pump housing, the hardfacing, and the method of application.

How much wear were you trying to repair?
