มาตรฐานคุณภาพ (Standard Compliance)
ISO9001:2015
Application Standard: AWS A5.15 ENiFe-CI
ISO 1071: ENiFe-CI
JIS Z 3252 DFCNiFe
Cast iron welding rod with a nickel-iron alloy core and a strong reducing graphite coating. Has the characteristics of high strength, good plasticity, and low linear expansion coefficient.
Application
Suitable for repair welding of important high-strength gray castings and ductile iron castings, such as cylinders, engine seats, gears, rollers, etc.
Welding Position
1G and 2F
Instructions
The rod should be baked at 80°C-120°C for 1hours before use.
The surfaces to be welded must be cleaned away impurities of oil contamination, rust, moisture and so on.
When welding, hammering the weld joint to dispel stress around the welding region to avoid crack.
To increase ability of crack-resisting and machinable, small current is recommended, meanwhile could reduce impurities to permeate the weld seam from base metal.
