Welding Rod Size For Metal Thickness Mm. It refers to the thickness of the core wire. 116 20 - 40.
Yield Stress 430 MPa Tensile Strength 490 MPa. The rod can be smaller however it will require more than one pass to complete the weld. Thats very roughly but it will depend what you are doing.
The amperage of the 6011 depends on the size and diameter of the rod.
Much of the plate thickness depends on joint prep such as a V or u groove. This will determine the diameter of the welding rod that you use. Except that the weld size need not exceed the thickness of the thinner part joined. Stabilizers in the flux make 6013 welding electrodes one of the simplest rods to use.
