Can aluminum profiles be welded or bolted together?

Yes, aluminum profiles can be both welded and bolted together. Welding aluminum requires specific techniques and equipment due to its high thermal conductivity, but it is possible and results in a strong joint. Bolting is a common method for joining aluminum profiles, as it is quick, easy, and does not require melting the material. It is important to use appropriate hardware and techniques to ensure a secure and durable connection.
