Abstract

The invention relates to a welding material technology, in particular to a nickel-base welding rod. The welding rod uses a SNi6062 welding wire as a core wire. The electrode coating comprises the following solid ingredients in percentage by mass: 36-50% of rutile, 2-7% of titanium pigment, 20-30% of fluorite, 3-8% of cryolite, 2-4% of phlogopite, 2-4% of zircon sand, 0.5-1.5% of sodium carbonate, 5-10% of manganese metal, 2-4% of ferrotitanium containing 25-35% of Ti, and 2-4% of ferroniobium containing 50-60% of Nb. The nickel-base welding rod has the advantages of favorable performance of production technique, smooth welding rod surface, high yield, stable eccentricity; during welding, the nickel-base welding rod has the advantages of stable electric arc, basically no splash, favorable slag detachability and outstanding operating performance; and the appearance of the welding seam is beautiful, the height of a weld bead is moderate, the wetting angle of a welding seam is moderate, and the strength and plasticity of deposited metals are moderate.

Description

technical field [0001] The present invention N relates to a technology in the field of welding materials, in particular to a nickel-based welding rod. Background technique [0002] With the development of industry, nickel-based alloys are used more and more widely. Nickel-based alloys refer to alloys based on nickel (Ni≥50%), containing other alloying elements, and resistant to corrosion in some media. There are mainly nickel, nickel-molybdenum (nickel-molybdenum-iron) alloy, nickel-chromium (nickel-iron) alloy, nickel-chromium-molybdenum and nickel-iron-chromium and so on. For example, nickel-based superalloys mainly used in the manufacture of aero-engine blades and high-temperature parts on rocket engines, nuclear reactors, and energy conversion equipment; nickel-based corrosion-resistant alloys used in the manufacture of various corrosion-resistant parts; through surfacing and spraying It is a nickel-based wear-resistant alloy that is coated on the surface of other base...
