Aluweld Flux Powder is a gas welding powder flux for welding aluminium and aluminium alloys. It is designed for pure aluminium castings that do not contain zinc. The flux works with a pure aluminium AL1188 filler rod and has an activity range of 550°C to 650°C. It is used with the full fusion technique and a neutral flame. With high activity and good fluidity, Aluweld supports the required flux action during aluminium welding.
 

Aluweld Flux Powder for Aluminium Welding

Aluweld is made for gas welding work on aluminium and its alloys. It is mainly suitable for pure aluminium castings without zinc. The product is supplied as a powder and is used with the specified pure aluminium filler rod.
 

Important product details include:

• Gas welding powder flux

• Suitable for aluminium and aluminium alloys

• Suitable for pure aluminium castings without zinc

• Activity range of 550°C to 650°C

• High activity

• Good fluidity

Welding Technique and Filler Rod

These features make Aluweld suitable for aluminium welding applications that match its stated material and temperature range.

 

Aluweld is used with the full fusion technique and a neutral flame. The recommended filler rod is AL1188 pure aluminium filler rod. The welding process should be selected according to the base material, filler rod, and working temperature.

 

The product is intended for applications where the welding temperature falls within its 550°C to 650°C activity range. Keeping the flux and filler rod suited to the working temperature is important for the intended use of the product.

 

Working Temperature

The activity range of Aluweld is 550°C to 650°C. This makes it a suitable option for the specified aluminium welding work within this range.

This information helps users check whether Aluweld matches their aluminium welding process before selecting the product.
 

Residue Cleaning After Welding

Aluweld produces water-soluble corrosive residues, so cleaning is an important part of the welding process. Residue should be removed after the welding work is complete.
 

The recommended cleaning process includes:

• Dip the welded area in dilute nitric acid.

• Rinse it with cold water.

• Rinse it again with hot water.

This cleaning process is specified for removing the flux residue after use. Proper residue removal should be included in the process when working with Aluweld.
 

Aluweld for Suitable Aluminium Applications
