I have both TIG and Oxy-Acetlyene welding capability. I was going to buy some welding rod for gas welding my chipper chute but then I thought maybe using TIG rod for steel wouldn't make any difference so far as weld strength etc. So why the distinction between TIG and gas rods? They're priced fairly close to the same. They look pretty much the same. And conversely, could you TIG weld with gas rod? Only talking mild steel here.
Reply:Yes you can oxy/acet weld mild steel with tig rod.
Reply:X3...The old timers used coat hangers from the beginning of time.......zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:I am going to respectfully disagree, on some levels, with the views of some of the responses here. There is a difference between the rods used for GTAW and those used for OAW. In application, GTAW filler metals that are used for their intended purpose will provide a clean, clear, welding puddle and a finished weld deposit with the appropriate strength requirements. If you use OAW filler for GTAW welding you may end up with a certain degree of porosity in the finished welds and you will also not have the intended yield strength in the finished weld, RG 45, RG 65, respectively 45,000 and 65,000 tensile strength. ER 70 S(x), will yield 70,000+tensile and is a filler for GTAW welding. If you weld with the ER 70(x) rod using the OAW process you might likely see a very cloudy weld pool that may be a bit sluggish in it's ability to move forward while you are welding, it may spark excessively as well. It will probably not have the same ductility as a weld performed with the RG rods designed for gas welding. Of course all of this is a moot point if the welds are not of a critical nature. If you can weld it and it holds, regardless of how it looks aesthetically, if the intended purpose is achieved it doesn't matter right? Look carefully at the chemical compositions of these two classes of fillers, this will give the story with regard to application and the differences. Just my $.02 for the conversation.

Reply:RG-45/60 have slightly lower silicon and manganese than 70s-6, but higher chromium, nickel, molybdenum and vanadium. End result: you're not going to see the difference with oxy fuel, but you might with TIG. Did you take the paper off the hangar?

Reply:They (I) used coathangers 'occaisonally' when out of rod.Used the hangers with a paper tube across the bottom, thinner wire, & stronger. The all metal ones were garbage rods, didnt work as well at all.-c-

They are classified on the basis of the minimum tensile strength of as-deposited weld metal.
