On the other hand, when working with aluminum that has been heat-treated, you have another set of problems. You will come across aluminum in hand rails through to food containers and vessels. After you have degreased, but before you weld, you need to remove this layer. A lot of people will take a rag or brush to wipe off the metal, but this won’t effectively remove grease; it may only move it around and make the situation worse. Clean the joint again if it isn't welded within that time. The softness of aluminum also means that the feeder wire may become tangled in the feeder during the weld if you aren’t careful. This will vastly reduce the opportunity for contaminants such as dust and moisture to enter the weld and weaken it. Remove oil, grease, and water vapor using an organic solvent such as acetone or a mild alkaline solution like a strong soap. First, it’s imperative that you make sure there’s no grease or oil on the metal to be welded. With certain alkaline solutions, you might need to immerse the parts to be welded into the liquid entirely. Another option is chemical removal. Aluminum, in contrast to other metals, has a low melting point; especially when compared to steel. Our employees respond to inquiries to the best of their ability based on information provided to them by the customers and the knowledge they may have concerning the application. The study evaluated the Oak Ridge Y-12 Plant's chemical cleaning, another type of chemical cleaning, ion cleaning, and diamond-machined cleaning. Thank you for the advice on the cleaning, was planning it already just didn't know if where the rest would be needed it or not. Take the following steps before welding aluminum: 2. To ease the challenge of this industrial process, cleaning the weld is essential. Our employees, however, are not in a position to verify the information provided or to evaluate the engineering requirements for the particular weldment. A wire brush, often called a wire scratch brush is used to take the final layer of Aluminum oxide off the sheet metal. While welding, the metal will be heated to a much higher temperature than during the original heat treatment process. To get help with material selection and more, please contact us today. 5.
