The purpose of the work was to determine the possibility of the regenerative surfacing of the upper surface of screw conveyor coils. The screw conveyor, used for the transport of bulk materials in a corrosive environment, was originally surfaced with chromium cast iron. The research work discussed in the article resulted in the development of a MAG method-based technology enabling the repair surfacing of screw conveyor coils. The technology involved the use of an EnDOtec DO*11 flux-cored wire and required the previous removal of the hardened upper layer.
