Aluminum welding process can be a challenging task because of the reason that the metal oxidizes in open air quite quickly. In addition, this oxidization process can also contaminate the weld even further that may bring fire in most of the cases.
Furthermore, it is a conductive metal and can cause a problem while welding at a lower voltage. As the heat generated by the weld can get depressed quickly, also, when you are welding using wire you may face problems. Because the aluminum wire is prone to bend, therefore, in order to successfully weld aluminum you need to take some precautionary measurements.
Here are some of the best methods that can be followed while welding with aluminum welding wire.
Use a welding wire tip to assemble the wire welder, but make sure you use the size larger than the wire you are using. In case the aluminum welding wire has the steel liner then you need to replace the same with plastic so that the wire won’t bind.
Place 1 mm wielding wire spool into the welder and feed the wire through the wire liner. You need to continue the feeding until it emerges from the wire tip of the welder.
Now you need to connect a tank of shielding gas as pure argon gas to the welding wire. This will secure you from the unwanted fire occurrences or blowouts caused by the oxidization present in the open air. Also, it will restrict the air oxygen from reacting with the metal that is processed for welding.
Then at this point, you need to clean the aluminum surface you are going to weld. For that, you need to use a steel brush that is primarily designed to use on the metal. Make sure the brush you are using is never been used on any other metal. Also, use the brush in only one direction to avoid distribution to the entire surface.
Make sure the welder you are using is fine and the tip is moving. So that, it will help you can prevent overheating of wire from a particular point. Aluminum observes the heat quickly, hence you need to move the welder forward. It will ensure the welding gets done quickly before they actually get the chance to cool down.
These are some quick and important steps you need to follow to successfully weld aluminum wire. In addition to that aluminum filler metal can be used to make it even stronger.
