Purpose and scope

Предназначена для исправления дефектов литья и ремонтной сварки высопрочного чугуна шаровидным графитом, может также применятся для сварки чугуна с пластинчатым графитом. 

Welding and technological properties

  • Arc Stability - consistent and stable arc behavior, good weld bead appearance. Spatter weldability to base metal is weak.
  • Slag crust virtually none. The pore resistance is high, the crack resistance is high when the product is preheated.
  • Shielding gas.: 100% СО2
 

Welding technology

  • The surface of the cast iron for welding or surfacing should be cleaned to a healthy metal.
  • Cutting and edge preparation should be carried out by machining.
  • When using fire cutting and stripping methods, cracking is possible.
  • The product must be preheated to 400-600°С, slow cooling.
  • Use DC direct polarity.
