  • How to TIG Weld Steel and Aluminum - Basics, Setup and Tips

    TIG welding steel and stainless steel are similar. You still need the same Tungsten electrode and Argon gas flow for both types of metal. But the main difference is that when you weld stainless steel you need immense gas coverage and should increase the gas flow. In certain situations, you will need to completely submerge the weld with Argon gas.
