Automotive industry industrial gas supply and equipment

Promote the all-round development of the automotive industry

Praxair supports customers in the production of high-quality components and equipment throughout the entire automotive and transportation equipment manufacturing process. Because the quality of the finished product depends on the production line, it is important to produce accurate, renewable parts. Praxair provides you with industrial gases, equipment, and advanced applications to help you with this task.

As the largest and oldest industrial gas manufacturer in North America, Praxair has a wealth of industry experience to meet customer requirements while respecting and protecting our planet. In some areas, such as wastewater treatment and solvent-free cleaning, Praxair products create a cleaner environment for automotive plants. In addition, Praxair applications can help you reduce defect rates, limit downtime and reduce emissions.

Automotive and transportation industry industrial gas, welding gas, shielding gas and laser gas

NitrogenNitrogen rollover Nitrogen

Nitrogen is suitable for tire retreading, autoclave inerting, and heat treatment of various automotive parts. It can also be used as auxiliary gas for laser cutting and plasma cutting. In addition, it can also be used in the production of heat shrinkable engines and transmission parts, seats, stereo systems, anti-lock brakes, and electronic components of air conditioning devices.

ArgonArgon rollover Argon

Assembly shop, 1s and 2s floors use argon and other welding gases to weld automotive parts such as exhaust systems, suspension systems, seats, axles and other components, because argon can provide the necessary gas environment for the strong welding of any material . In addition, argon is an important safety component of airbags.

HydrogenHydrogen rollover hydrogen

When hydrogen is used as a heat treatment furnace gas, it can react with oxygen to produce a shiny surface for steel parts. In addition, hydrogen can be used alone or mixed with other gases, and its high heat transfer performance makes it an excellent industrial quenching gas. When used as an alternative fuel in fuel cells or directly in internal combustion engines, hydrogen can also effectively reduce harmful gas emissions.

HeliumHelium rollover Helium

Helium is used to test radiator heat exchangers and torque converters to ensure that they are properly sealed. As an inert gas, helium can also be used in combination with argon to improve the performance of laser welding shielding gas and help the production of airbags. Helium is important for high-pressure gas quenching and is commonly used for low-pressure carburizing to minimize distortion of key components.

OxygenOxygen rollover oxygen

Oxygen can be used as plasma cutting gas and laser cutting auxiliary gas. It can be used in automobile painting and casting workshops.

AcetyleneAcetylene rollover Acetylene

Acetylene provides a high-precision carbon source for low-pressure carburizing processes. Its purity and transportation solvent ensure that carburizing is strictly controlled every cycle.
