Air Products’ weld process gases
are designed to deliver optimum
performance when TIG welding. All
of these gases meet the requirements
of ISO14175 / AWS 5.32 - “Welding
consumables — Gases and gas mixtures
for fusion welding and allied processes.”

industry to classify weld process gases. It
assists with the correct gas selection and
minimum quality control and labeling
requirements.
