KNi-60-4
Type of coating: Low hydrogen
KNi-60-4 is designed for welding in DC with good weldability and stable arc

Classification


Application and Features 

• KNi-60-4 is designed for welding in DC with good weldability and stable arc
• The weld metal contains low carbon to reduce carbide
• It provides good pitting corrosion and oxidation resistance at high temperature
• It is ideal for welding HASTELLOY C-276, nickel alloy and dissimilar materials

Welding Position

Welding Instruction

• Clean the surface of the base metal before welding.
• It is difficult for welding in V & O-H positions, so F welding is recommended.
• Baking temperature should be between 350~400°C during 30~60 minutes before welding. No PWHT is required for base metal.
• To avoid weave arc, make a short arc in low current.
• To avoid porosity, use the back step method for welding. (Please refer to Appendix A)

Application
- It is ideal for welding HASTELLOY C-276, nickel alloy and dissimilar materials
