KNi-60-7

Type of coating: Low hydrogen
KNi-60-7 is designed for welding in DC with good weldability

KNi-60-7 is designed for welding in DC with good weldability.
The weld metal has superior corrosion resistance to salt water, sulfuric acid, acetic acid and caustic soda.
It is ideal for welding valves, pumps accessories and pro-chemical facilities.

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)

It is ideal for welding valves, pumps accessories and pro-chemical facilities.
