Summary: | The invention provides a self-protection flux-cored wire and a preparation method thereof, and particularly relates to the field of welding materials. The self-protection flux-cored wire comprises a steel belt and a flux core filled in the steel belt, and the weight part of the flux core is 100 parts. The flux core comprises the following components in parts by weight: 25-40 parts of barium fluoride, 5-10 parts of fluorite, 1-3 parts of rare earth fluoride, 1-3 parts of potassium fluoride, 1.5-3.5 parts of barium carbonate, 3-8 parts of marble, 1.5-2.5 parts of graphite, 20-30 parts of aluminum-magnesium alloy, 10-20 parts of aluminum powder, 2-4 parts of aluminum iron, 1-3 parts of silicon-calcium alloy and the balance of iron powder. Deposited metal of the self-protection flux-cored wire has good mechanical property, tensile strength and yield strength, and carbon emission and the manganese content in smoke dust are reduced.
