Coreweld 88HS-Ni1 is recommended primarily for robotic or mechanized high speed welding of sheet steel. Welding speeds up to 90 ipm are possible when welding vertical down. The low slag level of Coreweld 88HS-Ni1 minimizes post weld clean up. For this reason, Coreweld 88HS-Ni1 gives special advantage in applications where post weld coating or painting is specified. Coreweld 88HS-Ni1 is a 1% nickel low alloy metal cored wire designed specifically for high speed welding where a clean weld surface is required. Coreweld 88HS-Ni1 deposits have very few silicon islands and almost no slag at the weld toes.
