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 300-350°С, slow cooling.
• Use DC direct polarity.
