Subject field(s)

DEF

A filler metal electrode consisting of a metal wire with a light coating applied subsequent to the drawing operation, primarily for stabilizing the arc. [Definition standardized by the AWS.]

CONT

Light coated electrodes have a definite composition. A light coating has been applied on the surface by washing, dipping, brushing, spraying, tumbling, or wiping to improve the stability and characteristics of the arc stream. They are listed under the E45 series in the electrode identification system.

OBS

The coating generally serves the following functions: a) It dissolves or reduces impurities such as oxides, sulfur, and phosphorus; b) It changes the surface tension of the molten metal so that the globules of metal leaving the end of the electrode are smaller and more frequent, making the flow of molten metal more uniform; c) It increases the arc stability by introducing materials readily ionized (i.e., changed into small particles with an electric charge) into the arc stream.

OBS

lightly coated electrode: term standardized by the American Welding Society (AWS).

OBS

lightly coated electrode: term officially approved by the Lexicon Project Committee (New Brunswick).
