The investigation tried to understand the effect of welding process and major welding parameters on dilution and its effect on corrosion resistance for a selected environment, by manufacturing and testing Alloy 625 weld overlays with different degrees of dilution on a carbon steel substrate material. (W 81) (1)

Corrosion resistance = Resistência à corrosão

The use of super-duplex filler-wire gave a weld with a little higher pitting resistance than ones made with matching composition 12Cr6Ni2Mo wire. (W 191) (2)

Pitting resistance = Resistência ao pite

The work presents experimental studies on the effect of crack depth and asymmetric geometries on ductile tearing resistance. (W 187) (3)

Tearing resistance = Resistência à ruptura
