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.
