Aluminum alloy overview:
Aluminum alloy is the most widely used non-ferrous metal structural material in industry.
It has been widely used in automobile, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of science and technology and industrial economy in recent years, the demand for welded structural parts of aluminum alloys is increasing, and the research on the weldability of aluminum alloys is also in-depth. The wide application of aluminum alloy has promoted the development of aluminum alloy welding technology, and the development of welding technology has expanded the application field of aluminum alloy, so the welding technology of aluminum alloy is becoming one of the hot spots of research.

The density of pure aluminum is small (ρ=2.7g/cm3), เกี่ยวกับ 1/3 of that of iron, and its melting point is low (660องศาเซลเซียส). Aluminum has a face-centered cubic structure, so it has high plasticity (δ: 32~40%, ψ:70~90%), easy to process, and can be made into various profiles and plates. ทนต่อการกัดกร่อนได้ดี; but the strength of pure aluminum is very low, the annealed state σb value is about 8kgf/mm2, so it is not suitable for structural materials. Through long-term production practice and scientific experiments, people have gradually strengthened aluminum by adding alloying elements and using heat treatment, which resulted in a series of aluminum alloys. The alloy formed by adding certain elements can have high strength while maintaining the advantages of pure aluminum such as light weight, and the σb value can reach 24-60kgf/mm2 respectively.

This makes its “specific strength” (the ratio of strength to specific gravity σb/ρ) better than many alloy steels, becoming an ideal structural material, widely used in machinery manufacturing, transportation machinery, power machinery and aviation industry, เป็นต้น. Aircraft fuselage , สกิน, compressors, เป็นต้น. are often made of aluminum alloy to reduce their weight. The welding of aluminum alloy instead of steel plate material can reduce the structural weight by more than 50%. Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. .

Aluminum alloys are divided into two categories: cast aluminum alloys, which are used in the cast state; deformed aluminum alloys, which can withstand pressure processing. It can be processed into aluminum alloy materials of various shapes and specifications. Mainly used in the manufacture of aviation equipment, building doors and windows, เป็นต้น. Aluminum alloys can be divided into deformed aluminum alloys and cast aluminum alloys according to processing methods. Deformed aluminum alloys are further divided into non-heat-treatable aluminum alloys and heat-treatable aluminum alloys. The non-heat-treatable type cannot improve the mechanical properties through heat treatment, but can only be strengthened through cold deformation. It mainly includes high-purity aluminum, industrial high-purity aluminum, อลูมิเนียมบริสุทธิ์อุตสาหกรรม, and anti-rust aluminum.

Heat-treatable and strengthened aluminum alloys can improve mechanical properties through heat treatment such as quenching and aging. It can be divided into duralumin, wrought aluminum, super duralumin and special aluminum alloys. Some aluminum alloys can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance. Cast aluminum alloys can be divided into aluminum-silicon alloys, aluminum-copper alloys, aluminum-magnesium alloys, aluminum-zinc alloys and aluminum rare earth alloys according to their chemical composition. ประสิทธิภาพที่ดี), special aluminum-silicon alloy (การรักษาความร้อนสามารถเสริมความแข็งแกร่งได้, high mechanical properties, good casting performance)。
