Welding GasBOC supplies a wide range of welding gases and associated welding equipment such as welding consumables, welding machines and safety equipment for all types of manufacturing processes.

The four most common welding processes are:

MIG (Metal Inert Gas) welding, also known as MAG (Metal Active Gas) welding and GMAW (Gas Metal Arc Welding). In Europe, the term 'MIG' is used only when a totally inert gas shield like argon is used, and 'MAG' when the shielding gas also contains active constituents, such as carbon dioxide or oxygen. MIG is a high-productivity continuous process requiring little downtime and can be used semi-automatically, automatically and robotically.

TIG (Tungsten Inert Gas) welding, also known as GTAW (Gas Tungsten Arc Welding). TIG welding tends to be used for intricate work and where a high-quality finish is required.

FCAW (Flux Cored Arc Welding). FCAW is mainly limited to carbon and low-alloy steels and some types of stainless steel.

MMA (Manual Metal Arc) welding, also known as SMAW (Shielded Metal Arc Welding). MMA is ideally suited to outside and site work because the electrode coating generates its own shielding gas.

For any welding application, it is important to choose the right gas for the job. You can find out more about the welding process and the welding gases and equipment that BOC supplies, along with how to buy them, by clicking on the links below.
