We supply argon as a totally inert gas to protect the molten weld pool from atmospheric contamination.

We supply a range of shielding gas mixtures -  that contain active components and can have beneficial impact on the welding process and the properties of the weld. Various shield mixtures are offered based on customer requirements.

The composition of our shielding gas mixtures is optimized for:

Material.

Thickness.

Welding position.

Welding technique.

A comprehensive range of Shielding Mixture Gases are available for various applications, and developed as per customer requirements. The following are major Shielding Mixtures.

Shielding mixtures – for MIG welding (For Carbon Steel, Alloy Steel and some stainless Steel).

ROC offers a range of shielding gases containing the following three gases:

                          Argon – for its ability to create the welding arc that allows spray transfer to be achieved, increasing the amount of weld metal deposited.

                          Carbon dioxide – to improve the size and shape of the weld bead through increased melting and improved fusion characteristics.

                          Oxygen – to reduce the surface tension of the molten metal and droplet sizes and therefore reduce the amount of welding wire needed, and the risk of cracks.

The combination of  mixtures can be tailored for welding a range of material thickness. The Shielding Mixture range provides improved welding performance with lower cost.

Shielding mixtures are only used for MIG welding and are suitable for:

Carbon steel.

Alloy steel.

Some stainless steels.

Shielding Mixtures – for MIG and TIG welding (For Aluminium and Aluminium Alloys, Copper and Copper Alloys, Carbon and Alloy Steels, Stainless Steel and nickel Alloys and Titanium).

ROC’s range of shielding gases containing the following two gases:

                      Helium – for its high thermal efficiency, transferring more energy from the arc into the weld.

                   Argon – for its ability to create the welding arc that allows spray transfer to be achieved, increasing the amount of weld metal deposited. But also because it produces a deep and broad penetration when coupled with helium.

The combination of the properties of the gases used in this range create mixtures tailored for welding a range of material thickness. The range of mixtures provide improved welding speed, increased deposition rates and reduced preheat requirements.

Mixtures are used for MIG and TIG welding and are suitable on the following materials:

Aluminium and aluminium alloys.

Copper and copper alloys.

Carbon and alloy steels.

Stainless steel and nickel alloys.

Titanium.

Shielding Mixtures – for MIG and TIG welding (For Stainless Steels and austenitic stainless Steel and Nickel Alloys).

ROC’s range of shielding gases containing either the following three gases:

                        Helium – for its high thermal efficiency, transferring more energy from the arc into the weld

                        Argon – for its ability to create the welding arc that allow spray transfer to be achieved, increasing the amount of weld metal deposited. But also because it produces a deep and broad penetration when coupled with helium.

                        Carbon dioxide – to improve the arc stability and the droplet transfer characteristics to reduce spatter.

Or the following two gases, for austenitic stainless steels:

                        Argon  –  for its ability to create the welding arc that allows spray transfer to be achieved, increasing the amount of weld metal deposited.

                          Hydrogen – to scavenge oxygen, give faster welding and a bright finish.

The mixture range allows smooth, clean and defect free welds in all grades of stainless steel and other materials.

Mixtures are used for MIG and TIG welding and are suitable on the following materials:

 Stainless steels and austenitic stainless steel.

   Nickel alloys.
