Characteristics and field of use UTP HydroCav is suitable for wear-resistant surfacings on weldments where high resistance to cavitation pitting, corrosion, pressure and impact is required, as for example in water turbine construction and pump construction. Due to the strong ability of work-hardening the weld deposit hardness under impact stress can be doubled. The main application field are surfacing on soft martensitic 13/4 CrNi-steels on Kaplan turbine blades. UTP HydroCav has good welding properties and is weldable in all positions, except vertical-down. It has a stable arc, even weld build-up, and good slag removability. Hardness of the pure weld deposit as-welding condition approx. 21 HRC After cold hardening approx. 50 HRC Typical analysis in % C Si Mn Cr Ni Co Fe 0,2 0,7 10,0 20,0 0,15 13,0 balance Welding instruction Clean welding area thoroughly to metallic bright. The interpass temperature should not exceed 250°C. Preheating of solid work pieces to 80 – 100°C is advantageous. Weld stick electrode with short arc and steep guidance. Redrying: 2h/300° C Welding positions Current type DC (+) / AC Recommended welding parameters Electrodes Ø x L [mm] 2,5 x 350 3,2 x 350 4,0 x 350 Amperage [A] 70 – 90 90 – 120 120 – 150
