Aluminum is one of the most widely used metals in the world because of its incredible durability, flexibility and, most importantly, recyclability. Recyclability means that aluminum can be used again and again, but one of the challenges of working with metals like aluminum is finding ways to join it.
Welding is the easiest way to join aluminum profiles, but it is not always the best or most cost-effective option. Fortunately, there are alternative ways to join profiles.
One of the easiest ways to connect hollow profiles without welding is to use frame connectors. Convenient and effective quick connectors are available, making the assembly of aluminum profiles extremely easy. These connectors can also be freely disconnected and reassembled, something that could never be achieved with welding, unless the aluminum materials are recycled and reprocessed. Other fasteners that can be used for aluminum profiles include screw connectors, cube connectors, corner inserts, end connectors and special fasteners for special or difficult connections.
Riveting is another way to connect aluminum g-k profiles. Riveting is a method we have known since World War I. We can choose from many rivets, but the principle of joining is the same. A central wire is pulled between the tubular rivets. During this process, the rivet expands, which creates a strong bond between the aluminum parts.
The first step to riveting aluminum is to properly prepare the aluminum. In particular, the aluminum should be cleaned, and any sharp edges of the aluminum should be sanded off - especially if the aluminum profiles are cut into smaller sizes. Once the surfaces are clean and smooth, you can consider how to line up the rivets. A good idea is to use a marker and a ruler. When you start joining, make sure the aluminum profiles are stable and held in place with clamps. If you make a mistake, don't worry, as you can always use a drill, remove the rivet and try again, although you will have to use a new rivet and discard the old one.
Aluminum brazing is a method that joins two or more pieces of aluminum together using molten filler material. Once the aluminum pieces are in place, the molten material will fill cracks and gaps. When it comes to joining aluminum profiles, the filler material should be a multi-metal alloy to improve the properties of the aluminum profiles. Most often, when it comes to bolting aluminum profiles, silver, copper, nickel or cobalt are used. Once the substance fills the voids between the aluminum pieces, it is cooled.
When preparing for the soldering process, get the proper protective clothing and equipment to prevent burns and other injuries. Covered footwear, flame-resistant clothing and protective gloves are essential equipment when soldering. In order for the bolting of aluminum profiles and their soldering to proceed properly, you must also prepare their surfaces properly. Aluminum profiles must therefore be cleaned. Soldering is similar to welding and is an effective method when it comes to joining aluminum profiles g-k, only if the surface is clean and free of dirt, especially dust. After the initial wiping with water and a cloth, it is then recommended to apply a degreasing solvent. After cleaning, smooth the surface for sharp edges and rough textures.
Joining closed profiles without welding using epoxy resin is a rather specific method. The biggest danger here is oxidation of the aluminum, because these bind much more difficult than when it is clean. To prevent this, the best solution is to apply a transparent coating to the aluminum surface.
Then, as with other methods, clean the surface thoroughly and coat it with a degreasing solvent. Only then are you ready to apply the adhesive.
