BOC Alushield Light Gas Cylinders
BOC's Alushield is a range of advanced shielding gases specially formulated for MIG and TIG welding aluminium over a wide range of thickness. Combining helium with argon these mixtures greatly improve welding speeds, increase deposition rates and reduce preheat requirements. Alushield will help a skilled welder to produce smooth, clean, defect free welds in all grades of aluminium.
Alushield Light
This mixture of 30% helium, balance argon is used for both MIG and TIG welding thin to medium section thicknesses. Fusion and penetration profiles are improved over pure argon as are its gap bridging capabilities reducing the chances of burn through. The addition of helium also helps to lower the levels of porosity reducing defect rates. Preheating will still be required for welding most thicknesses of copper but temperatures will be lower than for argon.
Benefits
Produces high-quality welds with good integrity, increased penetration and flatter weld beads
Produces improved fusion and reduced defects
Improved production rates and cost-efficiencies are achieved by increased welding speeds
