Aluminum Welding FAQ
Here are most of the questions related to aluminum welding. We hope you will find the answer to your question. If not, please leave us a message.
Yes, we can weld dissimilar aluminum alloy extrusions. Our team is well-trained and experienced in that kind of aluminum extrusion welding. We know that each aluminum alloy has specific properties, which can affect the welding aluminum extrusions results. For instance, the thermal expansion rate of 5xxx alloy aluminum extrusion welding differs from that of 7xxx alloy aluminum extrusion welding. By being keen on such specific properties and adhering to welding best practices, we can weld dissimilar aluminum extrusions successfully.
Yes, some aluminum alloy extrusions can be challenging to weld. Indeed, the level of welding difficulty varies from one material to the other. High-strength alloys such as 2024 alloy aluminum extrusion welding and 7075 alloy aluminum extrusion welding are good examples. They present welding issues related to solidification cracking and liquation. But some other alloys are simple to weld. Good examples are alloys in the 5xxx series and 6xxx series.
Warping in welding extruded aluminum is a serious problem that can occur due to uneven cooling in the heated part. We understand the dynamics of the heat-affected zone (HAZ) in different materials. We know the welding techniques and post-welding processes to handle such welding challenges. For instance, we apply an optimum welding speed depending on the specific alloy extrusion. Our technicians are also conversant in heat dissipation techniques when welding aluminum extrusions. Heat dissipation during welding helps prevent warping in aluminum extrusion welding.

Yes, our aluminum extrusion welding complies with various Chinese and international standards. All our aluminum extrusion welding processes follow the ISO3834 standards. Adherence to standards extends even to the type of personnel we have at FONNOV Aluminum. All our welders have undergone extensive training and received certifications according to ISO9606-2 and ISO14732 standards. Our advanced equipment and welding techniques help us further in adhering to the standards o welding aluminum extrusions.
Both of these welding techniques present different advantages in our aluminum fabrication projects. That’s why at FONNOV ALUMINIUM, we offer both manual welding and Robotic welding for aluminum. If you are looking for the appeal of human ingenuity, choose manual welding.
Modern manual welding is highly advanced. Welders can handle complex welds and a wide range of aluminum alloys. The efficiency and safety of the process have also increased significantly. Sometimes, it might even be difficult to differentiate between a weld done by a robot and one done manually.
That said, robotic welding for aluminum also has its unique features. It is ideal for fabrication processes that need to be safer – the worker is at a distance from the process. We use this welding aluminum extrusion method to perform different welding processes, including MIG. Depending on the processing requirements and the expected results for your alloy aluminum extrusion welding, either of the methods can be applicable.
We choose the best aluminum extrusion welding based on the specific project. Generally, we consider factors such as cost, repeatability, expected weld performance, and production speed. Others are the safety of the process, geometric limitations, and tolerance for distortion. It is important to consider these factors because welding aluminum can be challenging. You are looking at issues such as hot cracking, high thermal conductivity, oxidation, and porousness. The fact that the thickness of the aluminum extrusions can vary a lot makes the process even more challenging.
You may opt to use robotic welding for aluminum if you need advantages such as better weld quality, faster results, and reduced wastage. Robotic welding is automated, resulting in high repeatability and consistency of the weld. Naturally, a machine works faster than a human being. Robotic welding gives faster output with the same quality because it doesn’t suffer from fatigue. Robotic welding can lack flexibility and intuition, elements that manual welding brings to a project.
Yes, the thickness of the workpiece can determine how we perform a welding procedure. That’s because, among other things, the workpiece thickness can determine the amount of heat needed for effective welding. Thinner workpieces do not require as much heat as thicker materials do. If you don’t use the right welding method on a dense material, the welding aluminum extrusions may lack temperature consistency. This may result in cracking or distortion of the material. TIG welding is ideal for metal thicknesses of between 1mm and 6.5mm depending on whether it is a fillet weld or butt weld. MIG welding can weld fillet welds of up to 25mm thickness.
Certainly, there are a few other methods that you could consider for aluminum extrusion assembly. Some people go for mechanical joining solutions. Good examples of these are dovetails, snap joints, and screws. Another is adhesive bonding. This is a conventional joining method, but it is still evolving. You would choose this method if you are sure the joint will be permanent. It is also good for avoiding stress concentrations. Other than MIG and TIG welding, one can also use a different version of welding. Friction Stir Welding (FSW) is a perfect example of such an option. That said, our aluminum extrusion welding presents exciting benefits such as strict quality control and highly experienced welders.
Base your choice on different factors – desired visual outlook, alloy type, material thickness, etc. While the two welding methods are renowned in the aluminum fabrication world, their results and presentation may not be the same. Their working principles are different. TIG welding is based on the use of tungsten electrodes for the arc. As it melts the metal and a filler metal is applied, the welding joint is created. Instead of tungsten electrodes, MIG welding uses a consumable wire electrode. The process also incorporates a welding gun. During the MIG welding process, the weld must be shielded from contamination. TIG does a better job at controlling the heat intensity, but it is slower than MIG welding.
If you are unsure whether to use MIG or TIG, please consult our in-house team of welding experts.
Generally, aluminum alloys are considered suitable for welding aluminum extrusions. However, the capability to be welded for specific aluminum alloys can differ. The particular properties of an alloy determine how well you can weld that material. The most important aspect of the alloy is its chemical composition. For instance, 7075 alloy aluminum extrusion welding and others have high zinc content. They may be relatively difficult to weld. However, an alloy such as 5083 and 6061 alloy aluminum extrusion welding are easier to weld due to their different compositions. But remember that the welding technique also matters.
Yes, our bending and welding services are professional. By this, we mean that even as we create the applicable shapes and designs for the solar panel frame, we ensure that the products are structurally reliable. Our technicians weld and bend the 6005T6 aluminum extrusions with precision and within the structural limits. We seamlessly integrate the joints and components, reinforcing the respective areas for frames that can withstand the demands of the solar panels and related components.
Whether welding is required depends on the project. Some items require welding, while most projects require simple screw mounting.
Yes, but with a lot of skill and precaution. This is because 7075 aluminum extrusion is unique, particularly with its high heat sensitivity. One of the most important processes before welding the alloy is preheating. You need to do this to prevent material stresses and cracking. Next, you must get it right when choosing the filler material, otherwise, the weld joint won’t be strong enough. If you need to weld the material, we can share guidelines for safe and reliable results. So, you need the right techniques to weld the 7075 aluminum rods. Please note that welding the material for structural purposes can be unsafe.
Yes, you can weld 7075 aluminum angle. However, remember that generally, 7075 aluminum is challenging to weld.
Metal Inert Gas (MIG) welding is applicable. For the best results, make sure you clean the area thoroughly. Further, only apply filler material that is suitable for 7075 aluminum angle.
Yes, 7005 aluminum alloy has good weldability. However, care must be taken when welding this material considering that it is prone to oxidation. You can get strong welds from this aluminum alloy if you apply a welding technique that incorporates oxygen shielding. Argon is a popular oxygen-shielding gas – consider using it when welding 7005 aluminum extrusions.
The welding performance of 7075 aluminum is poor, we use MIG for 7075 aluminum tube welding, and we have rich experience on 7075 aluminum extrusion welding. CONTACT US for your welding request.
