TIG welding stainless steel vessel

Shielding Gases The right shielding gas or gas mixture to optimise any welding application.

Selecting the right shielding gas can optimise your welding results. Not only do shielding gases protect the finished weld from the effects of oxygen and nitrogen in the atmosphere, they can also have a positive effect on weld metal properties such as strength, corrosion resistance and toughness. In addition, they can optimise the weld bead shape and size as well as the weld porosity and fusion. And that’s not all – shielding gases can increase your productivity by accelerating the welding process and minimising the amount of spatter.

As one of the leading suppliers of industrial gases, we have a long-standing commitment to the welding industry. Our global team of application engineers have expertise in all shielding gas processes and can advise you on the mixture best suited to your individual application challenges. We back this up with extensive safety, training and maintenance support to keep your operations running smoothly.
