CAST IRON

Cast iron weld repairs are some of the most difficult weld repairs. The high level of carbon in cast iron (2-4%) can be converted to graphite during welding, which can cause cracking. To avoid this, 99% nickel consumables such as AI-1799-CI are used, and temperature control with maximum temperature of 780ºC and slow cooling is required. When welding without pre-heat, the casting must never get warmer than 50ºC.

AI-1755CI is a 55% nickel/45% iron which is suitable for cast iron repairs which do not require machining.
