Popis:	Raznovrsni uzorci (ASTM A387 Gr.12 + ASTM A240 TP 304L) platirani različitim postupcima (eksplozijskim zavarivanjem, elektrolučnim postupkom navarivanja pod prahom elektrodnom trakom (EPP) i toplim valjanjem) toplinski su obrađivani (650 °C tijekom 2 sata). Provedena su ispitivanja smične čvrstoće platiranog spoja i Charpy udarne radnje loma. Rezultati ispitivanja su statistički obrađeni te je utvrđena značajnost utjecaja postupka toplinske obradbe na slabljenje platiranog spoja. The dissimilar specimens (ASTM A387 Gr.12 + ASTM A240 TP 304L) clad by different procedures (explosion welding, submerged arc welding–surfacing using strip electrode (SAW) and hot rolling) were heat treated (650 °C through 2 hours). The shear strength testing of clad joints and Charpy impact energy testing were performed. The statistical analysis of testing results was elaborated, and the significance of heat treatment influences on the clad joints weakness was established.
