Products / Specialty Gases / Special Application / Welding Gas Mixtures

The technology of welding has increased manifolds in the past couple of decades and Engineers world over are switching to inert shields for a durable bond and a cosmetic finish.
SIGAS provide you a perfect answer to customers to meet their various needs.
Whether it is M.I.G., T.I.G., or Plasma weld, we can supply you the gas that precisely matches up to the job you have in mind. From Carbon steel to space age Titanium (and all metals in between) we have a high quality gas that matches most of a welding requiements to produce a first class result.
Besides our UHP Argon which is ideal for general applications, SIGAS Specialty gases offers you a range of welding mixtures for specific application.

Little splatter, increased weld speed, improved surface appearance.
Exellent weld bead profiles and appearance.
Enhanced penetration levels and welding speed, lesser gas flow required.
Best for spray transfer, stabilisation of Arc due to addition of Oxygen.
Hotter Arc, deep penetration, increased speed and defect control.
Hotter Arc, less porosity, removes oxides, lower flow rane than 100 % He.
Better result for spray transfer.

Enhanced results for section above 9 mm.
Increased weld-pool fluidity resulting in increased welding speed & less porosity
Best for surface and over laying.

Improved performance and penetration for thicker application.
Smoother finish, controlled speed and better penetration.

Cylinder pressure: 2000 psi Cylinder capacity: 43.6 & 10 Ltrs. of water
The above are available ex-stock. Please enquire for other cylinder sizes and tailor-made gas specifications.
Refilling of customers cylinders are also undertaken.
