What do the numbers mean on the stick welding rods?

The first two digits represent the resulting weld’s minimum tensile strength, measured in pounds per square inch (psi). The fourth digit represents the coating type and the type of welding current (AC, DC or both) that can be used with the electrode.

What do the numbers 7018 mean on a welding rod?

The 7018 Welding Rod The “E” in E7018 electrode indicates a tool used for an arc-welding process. The 70 means it makes welds that are very strong (70,000 psi). The 18 means two things: The “1” means the electrode can be used in any position, and the “18” means low hydrogen and usually DC current.

What does the 8 mean on a 7018 welding rod?

8 – the ‘8’ indicates that the rod has low hydrogen potassium with iron powder coating and that it can be used with all polarities (DC+, DC-, or AC). The final number, ‘8’ in the case of our E7018 rod, requires more explanation.

What do the 4 numbers on a welding rod mean?

The “E” indicates an arc welding electrode. So, “1” stands for an all position electrode, “2” for a flat and horizontal electrode, and “4” for a flat, horizontal, vertical down and overhead electrode. The last two digits specify the type of coating and the welding current.

What is the best all purpose welding rod?

Best Overall: Hobart 770458 6011 Stick Plus, these all-purpose electrodes are suitable for welding galvanized carbon steel and carbon, and they’re also used for welding with painted metals, rust, and dirt.

What is 4F means in welding?

Overhead Position
Overhead Position (4F or 4G) Overhead welding is performed from the underside of a joint.

What do the numbers on welding rods represent?

What Do the Numbers on Welding Rods Represent? Number Format. Numbers for mild or low alloy steel electrodes begin with an “E” prefix (meaning “electrode”) followed by a four or five-digit number in most cases. Tensile Strength. Position. Coating. Extra Numbers and Letters.

  • What are stainless steel welding rod numbers?

    The most common rod for stainless steel is 308, which works for base metals that are classified as either 304 or 308 using the AISI standard. Stainless steels, incidentally, are classified using three-digit numbers, falling mostly in the 200, 300 and 400 range. A common aluminum stick rod is 4043.

    What is a 6012 welding rod used for?

    The American Welding Society (AWS) classifies the 6012 welding rod as a popular stick electrode. Use 6012 welding rods to connect an open link between two joints . Professional welders use 6012 electrodes in the horizontal position for its speedy, high-current fillet welds.
