Argon: Inert and creates a clean protective atmosphere for high-quality welds in MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding, particularly for aluminium components like car bodies and frames.

Helium: Lighter than air, helium offers increased heat input and weld penetration, ideal for welding thicker metals or those requiring a more focused weld zone.

Carbon Dioxide: Used in specific mixtures with argon for cost-effective welding of certain steels, creating a good weld bead profile.

Nitrogen: Creates an inert atmosphere to prevent oxidation and achieve consistent material properties during carburizing, nitriding, and annealing processes that enhance the strength and durability of car parts.

Endothermic gas mixtures: Carefully formulated blends often containing nitrogen, hydrogen, and other gases, used to create specific temperature profiles for tailored heat treatment requirements.

Nitrogen: Plays a vital role in metal forming processes like stamping and pressing by preventing oxidation and ensuring consistent part quality.

Argon: Another option for inert gas purging used to remove air and moisture from storage tanks and equipment, preventing rust and maintaining a safe working environment.

Helium or Hydrogen (Specialty Gases): These light gases are used as specialized tracer gases to pinpoint leaks in car components efficiently due to their ability to escape through even the smallest openings.

Nitrogen: Used for inerting airbags during assembly and testing, ensuring their proper deployment in case of a collision.

Nitrogen or Hydrogen: Create a controlled atmosphere during brazing, a technique for joining heat exchangers in car air conditioning systems. This ensures clean, leak-proof connections.
