Aluminum-silicon-strontium-titanium-boron alloy welding wire and intelligent preparation method thereof

The invention belongs to the technical field of aluminum alloy welding materials, and relates to an aluminum-silicon-strontium-titanium-boron alloy welding wire and an intelligent preparation method thereof. The aluminum-silicon-strontium-titanium-boron alloy welding wire comprises the following components in percentage by mass: 4.5-7.0 wt% of silicon (Si); strontium (Sr): 0.005 to 0.05 wt%; titanium (Ti): 0.005 to 1.20 wt%; 0.0005 to 0.05 wt% of boron B; 0.0001 to 0.001 wt% of beryllium Be (Be); magnesium (Mg): 0.001 to 0.15 wt%; 0.001-0.5 wt% of copper (Cu), and the balance of aluminum and inevitable impurity elements; the content of inevitable impurity elements is less than 0.5 wt%. According to the aluminum-silicon-strontium-titanium-boron alloy welding wire, by controlling the components and the content of all the components, the whole alloy prepared through the advanced intelligent preparation technology has excellent performance in the aspects of welding wire material casting performance, welding wire
