Aluminum and aluminum alloy welding wires refer to the selection of joints according to the type of base metal, mechanical properties, and corrosion resistance requirements. In general, when welding aluminum and aluminum alloys, a thin plate with a chemical composition similar to the base metal is usually cut into strips as the welding wire. For heat-treated reinforced aluminum alloys with a greater tendency to weld hot cracks, welding wires with good crack resistance are mainly used.
Aluminum welding wire can be alloyed with other elements such as iron, Baidu aluminum, vanadium, or molybdenum, and is widely used in various fields, including aerospace (paint engines and spacecraft), military, industrial processes (chemical and petroleum PR); products, desalination paper, automobile, agricultural food, medicine (prosthesis, orthopedic transplantation, etc.). Dental instruments and fillers, kitchen utensils, sporting goods, jewelry, and mobile phones, etc. It also plays an immeasurable role in saving energy and reducing consumption in the automotive industry. Although titanium alloy parts have such excellent properties, there is still a long way to go before the widespread use of titanium and its alloys in the automotive industry. Reasons include high price, poor formability, and poor weldability. The main reason for the widespread use of titanium alloys in the automotive industry is the high cost.
Two useful properties of aluminum welding wire are corrosion resistance and the metal's strength-to-weight ratio. Titanium is similar in strength to some steels in its unalloyed state, but 45% lighter. The selection of welding wire is mainly based on the type of base metal, crack resistance of the joint, mechanical properties, and corrosion resistance. Sometimes, when a project becomes the main conflict, the focus of wire selection is to solve the problem. Take into account other requirements. In general, welding aluminum and aluminum alloys use the same or similar brand of welding wire as the base metal for better corrosion resistance. However, when welding hot cracks tend to be large heat treatment strengthened aluminum alloys, the selection of welding wire mainly starts from solving the crack resistance. At this time, the composition of the welding wire may be very different from the base metal.
