Abstract
The paper present some mechanical properties of dissimilar metal butt joints, performed between structural steel S355J0 and abrasion-resistant steel Hardox 450, using welding processes of MMA (111) and MAG (135). Taking advantage of this approach, it would be possible to replace the lining elements of the mining skip buckets in areas most exposed to the abrasive-dynamic degradation with Hardox 450 steel having better performance properties. Both dissimilar steel butt joints have tensile strength values higher than those of S355J0 steel. Heat input values that allow to the formation of high-quality joints by MMA method are higher than those required for MAG method. The metal-mineral abrasion resistance of dissimilar butt joints, performed by MMA and MAG welding procedures, is about 70% of those corresponding to Hardox 450 steel components.
