Abstract

A stainless steel electrode belongs to the field of welding materials, and is characterized in that chemical components of the electrode (in weight percent) include 40% of rutile, 8% of potassium feldspar, 3% of iron ores, 1.8% of potassium titanate, 1.8% of titanium white powder, 1.8% of metal chromium, 2.4% of fluorite (dried), 2.4% of cryolite, 8% of electrolytic manganese, 0.18% of bismuth oxide, 12% of micro-carbon ferrochromium, 7% of mica (dried), 1.5% of alginate calcium, 0.4% of ferroaluminium and 9.72% of marble. Compared with the prior art, the stainless steel electrode can generate arc, can also be melted to form filler metal for a welding line, and is high in corrosion resistance, and physical and chemical performances of deposited metal are stable.

Description

technical field [0001] The invention relates to a stainless steel welding rod. This stainless steel electrode establishes an arc that melts itself to form the filler metal of the weld. Has high corrosion resistance. Background technique [0002] At present, during the welding process of domestically developed electrodes, oxygen, nitrogen and water vapor in the air will immerse into the weld, not only forming pores, but also a small amount of oxygen entering the molten pool will oxidize the metal and alloy elements, and burn the alloy elements; high temperature of the arc Effect, the alloy elements of the weld metal will be evaporated and burned, and under the action of the arc blowing, the splash will also cause metal loss. The above reasons will reduce the mechanical properties of the weld. Contents of the invention [0003] The object of the present invention is to propose a stainless steel electrode with reasonable composition design. On the one hand, it can establish...
