What Is Function of Aluminum Welding Wire
Almost all welding methods can be used to weld aluminum and aluminum alloys, but aluminum and aluminum alloys have different adaptability to various welding methods, and various welding methods have their own application occasions. Gas welding and arc welding methods have simple equipment and convenient operation. Gas welding can be used for the repair welding of thin aluminum sheets and castings with low welding quality requirements.
Arc welding can be used for the repair welding of aluminum alloy castings. Inert gas shielded welding (TIG or MIG) is the most widely used welding method for aluminum and aluminum alloys. Tungsten inert gas AC argon arc welding or tungsten inert gas pulse argon arc welding can be used for aluminum and aluminum alloy thin plates.
Tungsten inert gas helium arc welding, argon-helium mixed tungsten inert gas shielded welding, metal inert gas shielded welding, and pulse metal inert gas shielded welding can be used for thick aluminum and aluminum alloy plates.
Several advanced processes for aluminum alloy welding: stir friction welding, laser welding, laser-arc hybrid welding, electron beam welding. Effective solutions have been proposed for alloys with poor weldability and alloys that were once considered unweldable. Several processes have advantages and can weld thick plate aluminum alloys.
Aluminum welding wire is an aluminum alloy welding material used for gas shielded welding and arc welding. It is usually composed of more than 99.5% pure aluminum and a small amount of alloying elements. It has excellent thermal conductivity and electrical conductivity and is easy to process and weld.
Aluminum welding wire is usually used to weld aluminum alloy products, such as aluminum alloy doors and windows, vehicle parts, aerospace equipment, ship components and electronic products. It can provide high-strength welding joints with good corrosion resistance and conductivity.
There are many types of aluminum welding wires, mainly including pure aluminum welding wire, aluminum silicon alloy welding wire, aluminum magnesium alloy welding wire, aluminum manganese alloy welding wire, etc. Different types of aluminum welding wires are suitable for different types of aluminum alloy materials and welding processes, and can meet various welding needs.
Pure aluminum welding wire is suitable for welding pure aluminum and aluminum alloys. It has high purity and good forming performance. It is suitable for various welding methods such as TIG gas shielded welding, MIG gas shielded welding and manual arc welding.
Aluminum silicon alloy welding wire is suitable for aluminum alloys with high silicon content. It has good thermal cracking resistance and fluidity. It is suitable for welding cast aluminum alloys. Aluminum magnesium alloy welding wire is suitable for aluminum alloys with high magnesium content. It has high strength and corrosion resistance.
It is suitable for welding aerospace and ship equipment. Aluminum manganese alloy welding wire is suitable for aluminum alloys with high manganese content. It has good mechanical properties and corrosion resistance. It is suitable for welding aluminum alloy doors and windows and vehicle parts.
The selection of welding wire is mainly based on the type of base material, the breaking performance of the joint, mechanical properties, corrosion resistance and the color coordination of the base material of the weld after anodizing. Usually, welding aluminum and aluminum alloys use welding wires of the same or similar grades as the base material, so that better corrosion resistance can be obtained; but when welding heat-treated strengthened aluminum alloys with a large tendency to hot cracking, the selection of welding wires is mainly based on solving the crack resistance. At this time, the composition of the welding wire is very different from that of the base material.
When using aluminum welding wire for welding, it is necessary to pay attention to maintaining appropriate welding current and welding speed, controlling welding temperature and gas protection, so as to ensure the quality and appearance of the welded joint. In short, aluminum welding wire is an important welding material for welding aluminum alloys. It has good welding performance and a wide range of applications. It is of great significance to the production and processing of various aluminum alloy products. Haomei Aluminum also has the anodized aluminum wire for welding.
