ABSTRACT:
A fabricated electrode is disclosed in the form of an elongated or continuous metallic sheath, composed for example of cold-rolled mild steel, and containing specific components somewhat uniformly distributed along its length, and for use in shielded-arc welding. Specifically, the composite provides a stainless steel and includes: a major percentage of iron; a limited amount, however, at least about 09.00 percent by weight of alloying metal, e.g. chromium; from about 0.01 to about 0.08 percent by weight of carbon and further including titanium in an unconventionally large amount [of at least about six times the percentage by weight of the carbon in the composite]. Advantages are disclosed for the provision of the titanium in the form of ferrotitanium, and the chromium in the form of ferrochromium, a major portion of which has a small particle size. Also as disclosed, the composite further includes deoxidizing agents, e.g. manganese and silicon.
