| titleOfInvention | Self-protection flux-cored wire for welding T2 copper and 304 stainless steel and preparation method thereof |
| abstract | The invention discloses a self-protection flux-cored wire for welding T2 copper and 304 stainless steel, which comprises a flux core and a welding skin, wherein the flux core comprises the following components in percentage by mass: nickel powder: 50% -60%, silicon powder: 2% -9%, titanium powder: 4% -8%, boron powder: 2% -4%, titanium dioxide: 1% -4%, rutile powder: 10% -13%, ferrosilicon powder: 1-2%, aluminum magnesium alloy powder: 2% -5%, cerium tetrafluoride: 1% -2%, calcium fluoride: 5% -9%, lithium carbonate: 1% -3%, zircon sand: 1 to 5 percent, and the sum of the mass percentages of the components is 100 percent. The flux-cored wire solves the problems that the fusion property of a bonding interface is poor and welding cracks are easy to generate when copper and steel are welded at present. The preparation method of the flux-cored wire is also provided, the raw materials are weighed according to the formula, then the raw material powders are mixed, the pure copper strip is used as a welding skin, and the diameter of the flux-cored wire is reduced to 0.8mm-1.6mm through a die in sequence. |
