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

Abstract

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 mechanical performance, welding quality and the like.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy welding wire, and relates to an aluminum-silicon-strontium-titanium-boron alloy welding wire and an intelligent preparation method thereof. Background technique [0002] With the acceleration of the optimization and upgrading of my country's industrial structure and the policy of energy conservation and consumption reduction, it has gradually become popular among the people, which has brought about the urgent demand for lightweight in industries such as high-speed rail, automobiles, rail transit, pressure vessels, shipbuilding, petrochemicals, aerospace, and military industries. , the demand for aluminum manufacturing products has grown rapidly, so the demand for high-performance aluminum and aluminum-based alloy welding wire products (hereinafter referred to as aluminum welding wire) has also increased rapidly. However, due to the late start and weak foundation of my country's industry, und...

Problems solved by technology

This traditional approach covers a large area, low space utilization rate, high storage cost for civil construction, high labor intensity, high safety hazards, low material turnover rate, low production efficiency, low degree of automation, and traditional manual management. In this way, inventory information cannot be grasped in real time, resulting in poor responsiveness of raw material allocation, long allocation cycle, low level of intelligent information management, high error rate of manual handling, and multiple handling, resulting in high costs of manpower, land, etc.

Even if such a large amount of manpower and material resources are invested, the occurrence of mixing cannot be completely eliminated, and the ratio of input to output is seriously disproportionate.
