Description

Ultra high strength steels have come into contention as basic structural materials with the advent of aircraft and missiles destined for supersonic flight. Fabrication of these steels demanded the concurrent development of welding electrodes to provide efficient and compatible welded joints for service at the ultra high strength levels. A low hydrogen coated electrode for use with AISI 4340 steel heat treated to ultra high strength levels was developed which exhibited satisfactory welding characteristics and deposited weld metal compatible with AISI 4340 steel at the ultra high strength level.
