Air Bags -
Air bags are a critical part of the active safety systems built into today’s vehicles. High-pressure argon, in combination with other rare gases, provides the right properties for ultra high-speed bag inflation. At Praxair, we also engineer high-pressure gas supply systems to integrate into air bag production lines.
One of our core competencies is using Praxair argon, carbon dioxide and helium to make precise, secure welds. Along with our industry-leading technologies, our gases are used for the welding of support struts, dashboard parts, frames and bodies during a vehicle’s trip down the assembly line.
Climate Control Systems -
Automotive air conditioning heat exchangers are often assembled using a brazing process done in a controlled nitrogen or hydrogen atmosphere. This reduction atmosphere allows the brazed joints to achieve the highest level of leak-free strength. Our helium is also commonly used for leak detection.
Today’s vehicles contain an ever-increasing level of computing power. Printed wire boards (PWBs) containing electronic components are made by a process called wave soldering and reflow soldering. Praxair nitrogen provides an inert atmosphere allowing the PWB soldering process to take place without defects, improving the quality of your electronic parts.
Many of our gases are also used in the manufacturing of semiconductors. More information can be found on the market pages for Electronics
Engine & Driveline Components -
When automakers look to increase fuel efficiency, they focus on transmissions and engines. And as automakers continue to engineer increasingly complex transmissions, our atmosphere technology for heat treating can maximize precision in this critical production phase.
Praxair’s ultra-high purity gases are an integral part of LED manufacturing. Energy efficient and long lasting, LEDs are the latest in automotive lighting. Our rare gases, xenon and krypton, are commonly used in light bulbs and our oxygen is commonly used in the glass furnaces supplying the glass for the lighting components.
Praxair pressurized nitrogen reliably and precisely contributes to the manufacturing process of automotive tires. We engineer nitrogen supply systems to deliver gas flows matched to the cycles of your tire curing machines. Inflating tires with nitrogen helps to increase tire life by stabilizing pressure and slowing rubber oxidation. This cost-effective solution eliminates the use of expensive liquid nitrogen pumps and gas receivers.

Praxair gases play an important role in several automotive glass processes. Our nitrogen and hydrogen are used in the production of float glass. Our oxy-fuel technology makes glass melting more fuel efficient while minimizing NOx emissions. And our spec gases result in glass deposition coatings for safety and energy efficiency.
