Welding at a glance
Welding is a welding process that joins workpieces, typically metals, by melting their edges so they fuse together. The primary method used is arc welding, which requires welding gas solutions to shield the liquid pool from ambient air. Argon-based mixtures are the industry's main shielding gases, ensuring high-quality welds. Additionally, laser welding is an advanced technique that provides precision and efficiency for various applications.
Our offer
Besides the argon-based mixtures, our range of premium gases can assist you in a better weld:
We also have a global network of hundreds of welding and cutting specialists that assist customers with programs aimed at reducing cost of operations, and optimizing for quality and speed.
