Stainless Steel is classified with a 300 code designation. Poorest grade is 302. Highest grade 347. Each grade contains a certain amount of Chromium and Nickel plus other elements. 308L (L means low carbon content) should be used for stainless with a 308 designation or below. It is recommended that you use the same electrode as the metal to be welded. Stainless to carbon steel usually requires a 309 electrode. L or ELC (Extra Low Carbon) is a plus. Food grade is usually type 316 . Use 316 on it.

309 stainless steel welding rod used to MS to SS 308 stainless steel welding rod only used to SS
The flux is the outer coating on a welding rod. The flux is a very important part of the welding rod.
not enough rod material was used
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
welding rod is used without applying current through it while the other one is, current is passing thru it..i.e. Welding rods are used in TIG welding process while Electrodes (E6011, E6013, E7017..etc..) is used in SMAW process
If you are referring to the small unusable piece of welding rod that is left after welding, most call it a electrode stub.

It stands for electrode. As opposed to R ( rod) for gas welding or TIG welding. If it carries electrical current it is an electrode.
An oxidizing flame is used in Braze welding. Not to be confused with Brazing, Braze welding uses bronze filler rod in a similar manner to fusion welding.
