Several different methods for joining aluminium extrusions exist, not only to each other but also to other materials.
Depending on your needs, and the requirements for your application,
we can offer the following methods:
Fusion welding uses heat, plus metal as a filler to join together two surfaces. The most common methods are TIG and MIG. TIG is most suitable for thin-walled materials and provides fine weld joints. MIG is used for welding thicker materials, has a higher welding speed but a worse finish at the weld joints.
Cold press welding joins together two pieces of aluminium without either heat or metal being added to the process. The joint is achieved when the specially formed seam areas of the profile are pressed together under high pressure and movement. This unites the atoms in the two pieces with a durable joint.
Soldering is suitable for thin product sizes, small details and when joining with other metals.
Riveting is carried out in the form of blind riveting or Tog-LLoc. Blind riveting is the most common method and is carried out without a holding-up tool. Tog-L-Loc is carried out without the addition of other material and is done with the help of a support tool.
Screw joints are most often used where it has to be possible to dismantle the joint.
