Tig Welding For Carbon Steel. Specification for Carbon Steel Electrodes and Fluxes for Submerged Arc Welding. Specification for Carbon Steel Electrodes for Flux Cored Arc Welding.
But hot rolled is another story. Tig Welding Steel. Argon Carbon Dioxide mix works for MIG welding but will spit and pop and make a total mess of a TIG weld.

Topic Welding Industry Technical Discussions argon purging in TIG welding of carbon By pdprao Date 03-09-2003 1726 At present we are welding ASTM A333 Gr 6 pipes with TIG process with flat consumable inserts with inert gas backing for puging. Things start to get more difficult as carbon content increases. The polarity typically used is DCEN direct current electrode negative Argon gas and Thorium Tungsten. In TIG the arc length is associated with the voltage so with a longer arc the voltage increase consequently with a shorter arc the voltage decrease.
