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.
