BOC Shielding gases are being used by
a wide range of industries helping our customers to raise quality and productivity
standards and operate more cost -effectively and safely. For industries using the GMAW,
GTAW and FCAW processes for welding there are a number of application areas for our gas
mixtures. In addition they are also used for Plasma welding and cutting of sheets plates
in some industries.
