Adding hydrogen to argon in welding can significantly enhance welding performance, especially when working with austenitic stainless steel. This specialized gas mixture offers several advantages, which we outline in this guide. To help you get the most out of hydrogen and argon, we’ll also go over the key considerations and safety tips to follow. Enhanced …

Pure argon is the most common gas used to weld stainless steel, especially for TIG welding of thin materials. For thicker stainless steel or MIG welding applications, specialized mixtures like argon-helium, argon-CO₂, or tri-mix gases provide better penetration and arc stability. In this guide, you’ll learn how different shielding gases affect stainless steel welding quality …

Carbon dioxide (CO2) is the shielding gas that provides the best penetration for Flux-Cored Arc Welding (FCAW) processes. It creates deeper and broader weld penetration profiles than other options, which makes it ideal for applications requiring maximum joint strength. In this article, we’ll explain why CO2 excels at improving penetration and how different shielding gases …

You can weld with nitrogen, but only in specific applications. Nitrogen isn’t typically used as a primary shielding gas like argon or helium, but it serves valuable purposes in specialized welding scenarios. In this article, we’ll go over those scenarios to explain when you should use nitrogen in welding. We’ll also explore its advantages and …
