HOW TO CLEAN ALUMINIUM WELDS

Do’s and Don’ts of Cleaning Aluminium Welds

Methods of Cleaning Aluminium Welds

There are two ways in which the joint can be prepared for welding. The first step involves the mechanical removal of the oxide layer to make it more controllable. For your information, the oxide layer’s melting point is greater than that of the base metal. The second step to cleaning aluminium weld deals with the elimination of oil, grease, air borne dust or moisture that hampers the usefulness of the weld.

Do’s and Don’ts of Cleaning Aluminium Welds

Cleaning aluminium welds is a procedure that requires extra care and attention. A faulty method of cleaning the weld can lead to a defective aluminium product. There are a number of rules to be followed for cleaning aluminium welds. Each step in the cleaning process must be performed meticulously. Here is a list of do’s and don’ts for cleaning aluminium welds.

1. Cutting methods that leave a ground or smeared surfaced should not be used under any circumstance.

2. Use of oxy-fuel gas cutting, carbon arc cutting, gauging processes or oxy-fuel flames for pre heating should be avoided.

3. Lubricants should never be used in aluminium welding applications.

4. Oil and grease comes attached to the aluminium from the factory. The joint should be cleaned before assembly.

5. Shop rags should never be used to clean the welding joint. Oil and dirt can be transferred from these rags into the welding surface.

6. A wire brush can be used to clean the joint only after solvent cleaning is complete, otherwise hydrocarbons and other contaminants will be implanted on the surface of the welding joint.

7. Never blow off the joint with compressed air. Moisture and oil contaminants are often present in compressed air.
