Gas Welding Aluminium Flux. The flux works ok but the operating window is tight. Gas metal arc welding GMAW commonly referred to as metal inert gas MIG welding is another common method used for aluminum welding.
You can make a little tray and rotate the rod in it before welding. Flux is used to remove any aluminum oxide from forming during heating and to prevent the metal from oxidizing at the same time. When flux is used the oxide breaks down and turns them into a fusible slag.
For Fusion Welding Aluminium Alloys Highest Quality Flux Useable in either Powder or Paste Form.
Gas metal arc welding GMAW commonly referred to as metal inert gas MIG welding is another common method used for aluminum welding. Gas metal arc welding GMAW commonly referred to as metal inert gas MIG welding is another common method used for aluminum welding. It eliminates the need for a number of different types of aluminium welding alloys. Flux in Aluminium In the welding of aluminum welding flux is necessary due to the formation of oxide film on the metal which will prevent the sound welds.
