When we ask what the smallest welding rod available is, the answer is simple; it is the 6012 rod. Although they are the smallest, they are still designed to be super resilient and are best used to meld two joints together. However, that’s not all since they can also be utilized in the horizontal high current fillet and high-speed welds.
Its initial 2 numbers denote its overall tensile strength while the 3rd number has been added to signify that this electrode can be utilized in all positions. Therefore it is quite versatile in usage. The last and final number will let users know exactly what kind of coating it has and the compatible welding current.
