KNi-70C Stick Electrode

详情

KNi-70C
Type of coating: Low hydrogen
KNi-70C is an all position electrode for welding in DC with good weldability

Classification


Application and Features 

• KNi-70C is an all position electrode for welding in DC with good weldability
• It provides good heat and corrosion resistance to high temperature (<480°C)
• It has good toughness to low temperature
• It is used for welding pressure and chemical tanks

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 used for welding pressure and chemical tanks
