Description
FILLER METAL Alloy 55 is used for TIG and MIG welding of cast iron. This filler metal is extensively employed to overlay the cast iron rolls. It is also used to repair the castings. The weld metal of FILLER METAL Alloy 55 is harder than that of FILLER METAL Alloy 99. However, the machining can be accomplished by u sing carbide tipped tools. A preheat and interpass temperature of 350ºF (175ºC) minimum is recommended during welding, without which the weld and heat affected zones could develop cracks.
