BOC Alushield ( 50% Helium) Universal 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 Universal
A 50% mixture of argon and helium is used for manual and semiautomatic MIG and TIG welding. It produces a more fluid weld pool than Alushield Light, and so tends to be used on thicker components. Fusion and penetration are excellent reducing defect rates, improving productivity while reducing costs.
The high energy available means that little or no preheating is required when welding thicker aluminium sections or copper and that in some cases weld preparations can be reduced in size further reducing cost.
Benefits
50% helium & 50% argon mixture
Produces flatter, neater weld beads in MIG welding and uses less wire for better efficiencies
Produces greater weld speeds and improved weld integrity with high-quality fusion profiles
Provides reduced preheat times with flatter weld beads, less clean-up and lower defect rates when MIG or TIG welding copper alloys
Improves electrical conductivity of welding components
