Abstract

The invention relates to the field of flux-cored wires, in particular to a strengthened flux-cored wire. The flux-cored wire comprises following components including, by mass percent, 30%-42% of rutile, 4%-7% of quartz, 2%-5% of magnesia, 3%-6% of potassium fluoride, 11%-14% of arc stabilizer, 5%-8% of ferrotitanium, 6%-9% of a silicomanganese alloy, 8%-11% of niobium powder, 1%-5% of calcium fluoride, 4%-7% of iron powder and the balance hafnium powder. The strengthened flux-cored wire is more durable than a conventional flux-cored wire.

Description

technical field [0001] The invention relates to the field of flux-cored welding wires, in particular to reinforced flux-cored welding wires. Background technique [0002] Flux-cored wire is a new type of welding material, which has the advantages of high benefit, low cost, high quality, etc. It inherits the adjustable electrode composition, overcomes the shortcomings of non-continuous and automatic welding of electrodes, and has high efficiency. , weld forming smooth and beautiful and a series of advantages. Compared with solid cored wire, flux cored wire has the following characteristics: high production efficiency, flexible composition adjustment, energy saving and low pollution. For example, in the shipbuilding industry, flux-cored welding wire has replaced manual welding rods and solid welding wires, and has become the most consuming welding material. With its excellent properties of high strength, high toughness, crack resistance and porosity resistance, it has become ...
