Abstract
Under the Direction of the
AWS Technical Activities Committee
Approved by the
AWS Board of Directors
This specifcation prescribes the requirements fr classifcation of carbon steel electrodes fr fux cored arc welding.
The requirements include chemical composition and mechanical properties of the weld metal and certain usability
characteristics. It also includes optional supplemental designators fr lower temperature toughness requirements, difusible
hydrogen limits, αnd shielding gαs range designators. Additional requirements are included fr standard sizes, marking,
manufcturing, and packaging. A guide is appended to the specifcation as a source of information concerning the
classifcation system employed and the intended use of carbon steel fux cored electrodes. This specifcation makes use
of both U.S. Customary Units and the International System of Units (SI). Since these are not equivalent, each system
must be used independently of the other. |
