Aluminum welding wire rods are widely used as filler materials for aluminum alloy argon arc welding and gas welding. The selection of welding wire should be based on the type of welding target, and the requirements of joint crack resistance, mechanical properties and corrosion resistance should be considered comprehensively. Under normal circumstances, welding aluminum and aluminum alloys are welded with the same or similar grade of welding wire as the welding target. For example, if the welding target alloy is 1060, then we need to use 1060 aluminum welding wire, if the welding target is 5183 or 5 series Aluminum alloy, then if we choose aluminum welding wire rods, we can choose 5183 aluminum welding wire, the aluminum welding color is similar to 5183 alloy, such as aluminum mig welding wire 5356, 5554 aluminum welding wire, 5556 aluminum welding wire, which can get better corrosion resistance. However, if the welding target is heat-treated-strengthened aluminum alloy with a high tendency of welding hot cracking, the choice of welding wire is mainly to solve the crack resistance. At this time, the composition of the welding wire is very different from the composition of the welding target.

2. Aluminum electrode has a low melting point, good wettability and the ability to fill gaps;

3, aluminum electrode has high strength, good plasticity, conductivity and corrosion resistance;

Aluminum welding wire types

Aluminum welding wire can be brazed by melting argon arc welding (MIG welding), tungsten argon arc welding (TIG welding), gas welding and plasma arc welding.

Argon arc welding is a more perfect method for welding aluminum and aluminum alloys. Due to the protective effect of argon and the cathodic crushing effect of argon ions on the oxide film, argon arc welding can eliminate the need for flux, which avoids the corrosion of the joints by residues after welding.

In addition, the argon flow scouring the welding area during welding significantly cools the joint, thereby improving the structure and performance of the joint. TIG welding or MIG welding can be used for argon arc welding. MIG and TIG welding methods mainly use pure Ar as the shielding gas. Thin plate structures are generally welded by hand TIG, while thick plates are welded by MIG. In TIG welding, AC power is generally used, while DC reverse connection is used in MIG welding. According to the different welding methods, we use different aluminum welding wire types. If it is MIG welding, aluminum mig welding wire is required, and if it is TIG welding, aluminum tig welding wire is required.

Aluminum MIG welding wire

Aluminum mig welding wire is the aluminum welding wire used when the MIG welding method is adopted. MIG (Metal Inert-Gas Welding) welding is molten inert gas shielded arc welding, which uses inert gas such as Ar as the main protective gas, including pure Ar or Ar A small amount of active gas (such as less than 2% O2 or less than 5% CO2 gas) is mixed with a small amount of active gas in the gas to carry out the welding method of molten electrode arc welding. When MIG welding aluminum, because the melting speed of the aluminum welding wire is very fast, the wire feeding speed is high; the aluminum welding wire has low rigidity and is relatively soft. When welding, the thin welding wire is easy to bend, which affects the normal welding. Therefore, aluminum mig welding wire is generally used. MIG welding wire is generally coiled or disk-shaped.

Aluminum flux core welding wire & rods

aluminum flux core wire welding is also called aluminum alloy brazing sheet. When brazing aluminum alloy using brazing under vacuum, vacuum brazing, flame brazing, high frequency brazing, etc., it is supplemented with aluminum brazing solvent. (Commonly known as aluminum solder) will work better together. When the aluminum alloy is brazed, the difference between the melting points of the brazing material and the weldment is very small, so it is more accurate in terms of temperature adjustment than other brazing requirements.
