How to choose mixed gas when welding?
Welding mixed shielding gas is designed to improve the quality of welds. The gases required for the mixed gas are also the common welding shielding gases such as oxygen, carbon dioxide, argon, etc. Using mixed gas instead of single gas for welding protection has a good effect of significantly ref...Read more -
Environmental testing requirements for standard gases / calibration gas
In environmental testing, standard gas is the key to ensure measurement accuracy and reliability. The following are some of the main requirements for standard gas: Gas purity High purity: The purity of the standard gas should be higher than 99.9%, or even close to 100%, to avoid interference of i...Read more -
