Cobalt Alloy, Corrosion and Heat-Resistant, Covered Welding Electrodes 51.5Co - 20Cr - 10Ni - 15W
Includes all amendments and changes through Reaffirmation Notice , July 2012
Published By:SAE International (SAE)
This specification covers a corrosion and heat-resistant cobalt alloy in the form of covered welding electrodes.
These electrodes have been used typically for shielded-metal-arc welding of parts fabricated from material of similar composition, particularly when the weld zone is required to have corrosion and heat resistance comparable to that of the parent metal, but usage is not limited to such applications.
The electrodes covered by this specification are classified as follows:
Type A - DC
Type B - DC - AC
Type C - DC
Type D - DC – AC
When DC is specified, reverse polarity (electrode positive) is required.
If a type is not specified, Type A shall be supplied.
Lime-type coverings are required for Types A and C electrodes.
