Linkweld 55 GRAPHITE TYPE
Characteristics and Applications: Linkweld 55 is a covered electrode with graphite type coating and Fe-Ni alloy core rod. The weld metal provides low expansion coefficient, less hardening and good machining property. It is suitable for ductile cast iron, malleable cast iron and gray cast iron.
Notes on Usage: 1.Hot peening prevent the shrinkage stress. 2.Clean up to prevent contamination. 3.Preheat the base metal at 300℃, PWHT at 500-600℃. 4.Use small amperage and keep the arc as short as possible.
