| Industries / Applications |
| |
| 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. |
