KNi-70B Stick Electrode

Description

KNi-70B
Type of coating: Low hydrogen
KNi-70B is designed for welding in DC

Classification


Application and Features 

• KNi-70B is designed for welding in DC.
• It provides good heat and corrosion resistance at high temperature (<980°C).
• It is ideal for welding Ni-Cr-Fe alloy, 9%Ni steel, forged/casting working pieces, and dissimilar materials (carbon steel, stainless steel, nickel or nickel-based alloy)

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
- Ideal for welding Ni-Cr-Fe alloy, 9%Ni steel, forged/casting working pieces, and dissimilar materials (carbon steel, stainless steel, nickel or nickel-based alloy)
