Problem m
When welding to ductile iron or cast iron, the
weld does not “stick” to the surface.
Remedy:
1. Remove all coatings before cleaning.
2. Clean the surface with a rasp or grinder to bright
metal. When grinding, use an ERICO-approved
wheel only.
3. Clean the surface with a safety solvent after
grinding or rasping.
4. Use CADWELD
® XF-19 alloy welding material
(orange cap).
CADWELD ® ONE SHOT connections do not always
follow the same rules as connections made with
graphite molds.
1. No portion of the cable within the confines of
the sleeve should be exposed.
2. Maximum depression under the riser (after
the slag has been removed) should be no lower
than the bottom of the cable. Lower fill indicates
excessive leakage of molten metal or improper
positioning of the CADWELD ONE SHOT mold.
