Nickel 99 (ENi-Cl) welding electrode is
designed for welding gray iron castings to
themselves as well as joining them to mild
or stainless steels. It is also used to repair
castings. With the high nickel content, the
welds are easily machined. A preheat and
interpass temperature of not less than 350ºF
is recommended during welding.
