> Aluminum TIG welding rods

Aluminum tig welding rod also know as tig aluminum filler rod, used for electrodeless argon arc welding, tungsten argon arc welding is characterized by easy operation, concentrated heat, good protection effect, beautiful weld formation, good quality, and deformation of the weldment small. Generally, argon arc welding is used for welding aluminum and aluminum alloy components with high quality requirements.

Aluminum welding rod wires can be divided into welding wires of the same material and welding rod wires of different materials. Generally, a welding rod wire with the same chemical composition as the base metal or a slat cut from the base metal is used as the filler metal, that is, the same material welding rod wire. Welding rod wires of different materials are developed to meet the requirements of crack resistance. The commonly used heterogeneous welding rod wire is SAISis. The welding wire has good fluidity when liquid, and has a small solidification shrinkage. The weld metal has high crack resistance. It is often used for welding. Aluminum alloys other than aluminum-magnesium alloys. When welding aluminum-magnesium alloys, aluminum-magnesium welding rod &wire with a magnesium content of 1% to 2% higher than that of the base metal should be selected. The diameter of welding rod & wire for welding aluminum castings can be thicker, generally 5~8mm

Aluminum-magnesium alloy is what we usually call 5 series aluminum alloy. The addition of magnesium to aluminum has good weldability, has minimal strength loss, and is not easy to crack. If TIG is used to weld aluminum-magnesium alloys, the choice of welding  rod & wire  Generally it is ER5356, as well as ER5183 and ER5556. 5 series alloys are often used in shipbuilding. For this reason, ER5356, ER5183 and ER5556 are commonly used in the welding process of shipbuilding. On the other hand, you can also choose aluminum-silicon alloys, such as 4043 aluminum tig welding rod and 4047 aluminum tig rod. Silicon can increase the fluidity of the molten pool and improve the weldability.

best aluminum tig welding rod

There is no difference between the best and the worst for aluminum tig welding rod. It depends on which kind of base material the customer is welding. The best aluminum tig welding rod is the best aluminum tig welding rod by choosing the welding wire that matches the base material better. In the welding process, we must choose the right welding wire. Different aluminum plates have different requirements for welding wire. We need to choose the welding wire that matches the compression and tensile capabilities.

5183 vs 5356 aluminum tig rod

The selection of welding wire is mainly based on the comprehensive consideration of the type of base material and the requirements of joint crack resistance, mechanical properties and corrosion resistance. Sometimes, when a certain item becomes the main contradiction, the choice of welding wire will focus on solving this problem, taking into account other requirements.

tig welding aluminum filler rod

In aluminum alloy welding, the structural composition of the weld metal determines the strength, plasticity, crack resistance, and corrosion resistance of the weld. Therefore, a reasonable choice of tig welding aluminum filler rod is very important. When selecting a welding wire, first consider the composition of the basic metal, the specific requirements of the product, and the construction conditions. In addition to meeting the mechanical properties and corrosion resistance of the welded joint, the rigidity and crack resistance of the structure should also be considered.
