*2.4. Abrasion Resistant Layer Deposited by Covered ABRADUR 64 Electrode*

The abrasion-resistant layer was deposited by manual welding of an S335JR steel with a covered electrode, DIN 8555: E 10-UM-65-GR with a diameter of 5.0 mm and a welding current of 270 A. The welding process was carried out using a buffer layer made with a covered electrode, ERWS 19-12-3 L with a diameter of 3.25 mm and a welding current of 110 A, as shown in Figure 4. The purpose of the buffer layer was to transfer the stresses between the base material and hardfacing. The chemical composition and properties of the weld metal, ABRADUR 64 are given in Table 4.
