AS 1553.1-1983

Defines a classification system for the electrodes and specifies two series which provide weld metal strengths of approximately 410 and 480 MPa in a range of grades identified by Charpy V-notch impact tests on deposited metal at specific temperatures. Provision is made for hydrogen controlled and metal-enriched electrodes. Requirements are given for size of electrodes, core wire, flux covering, testing, safety warnings, packing, marking and storage. Tests include chemical analysis of weld metal, all weld tensile and impact tests, butt-weld tensile, bend and impact tests, and a fillet break test and a hydrogen test are also prescribed.
