315 designates the type of stainless steel (amounts of Nickel and Chromium added to steel). Therefore you should use type 315 electrodes (rod) to weld it. 302 would be the lowest or poorest type of stainless, 327 a much higher quality. 316 is considered "food grade" and used in cooking and food preparation utensils.
The flux is the outer coating on a welding rod. The flux is a very important part of the welding rod.
welding rod chemical formula?
for steel structure building can i use: -size 2.5mm of 7016 welding rod as a filler for welding IPE240 to plates -size 2.5mm of 7016 welding rod as 2nd pass
It stands for electrode. As opposed to R ( rod) for gas welding or TIG welding. If it carries electrical current it is an electrode.
E, eletric welding. R, rod or filler. 70, tensile strength. S, solid wire. 6, chemical composition.
720

To get a smooth welding action, you need to strike a proper spark that gets the Rod melting properly.
I am not aware of a cast iron rod for oxy acetylene welding, I am for arc welding, For cast, I use a brazing rod, a brass or copper alloy, but what do I know. If there is a cast rod available, it would be the same process, get the cast you are welding hot almost to the point of melting, bring in the rod, heat it at the same place and bring both to a melting point. Work from that point along the crack or joint you are welding. ----------------------------------------------------------------------------------------------------------------- You need not use brazing rod for case iron welding. You get arc welding electrodes for cast iron. Use appropriate grade of rod for your case iron under welding.
