摘要： A tubular composite self-shielded arc welding electrode comprising a metallic outer sheath and a core within and enclosed by the sheath, the core comprising about 15 percent to about 60 percent of the electrode weight and consisting essentially of the following listed components in the specified weight percentages of the electrode: from about 1 percent to about 7 percent of at least one slag former, from about 0.5 percent to about 6 percent of at least one fluxing agent, up to about 3.2 percent of at least one arc stabilizer selected from the group consisting of calcium titanate, potassium titanate, potassium-bearing frit, sodium titanate and sodium-bearing frit, from 1.25 percent to about 4 percent of deoxidizer metal including at least 1 percent manganese and at least 0.25 percent silicon, and from about 12 percent to about 55 percent of other metal-bearing materials selected from the group consisting of metals, metal alloys and ferroalloys, the electrode being formulated to produce a highalloy deposit of a type selected from austenitic chromium-nickel stainless steels and nickel-base alloys. In a preferred form the electrode may contain up to about 3 percent by weight of at least one fissure-reducing agent selected from the group consisting of alloyed and unalloyed metallic forms of calcium, magnesium and titanium.
