BOC Alushield shielding gases are developed specifically for MIG, TIG and plasma welding of aluminium and copper.
BOC Alushield shielding gases are also suitable for MIG and TIG welding copper and titanium alloys, as well as for TIG welding nickel alloys, stainless steel, carbon and alloy steels, where heat transfer or high welding speeds are important, such as in automatic welding applications such as tube mills.
Helium-containing shielding gases allow more energy to be transferred into the weld than pure argon, but the addition of argon improves the arc stability and initiation. The Alushield range of gases will help a skilled welder to produce smooth, even and defect-free aluminium welds.
There are three gases in the BOC Alushield range, each designed to weld varying thicknesses of material: Alushield Light, Alushield Universal and Alushield Heavy.
