The article presents results of tests concerning the metal-mineral abrasive wear resistance of butt welded joints with abrasion-resistance overlay weld HARDPLATE 100S 5+3 made using a covered electrode with the solid core and the flux core as well as a self-shielded flux-cored wire. The significance of the above-named effect was determined using a completely randomized design. The scope of tests also included the analysis of the chemical and phase compositions, hardness measurements as well as the macro and microscopic metallographic tests of welded joints in abrasion-resistant plates.
