What are the 4 classifications of electrodes?

1 indicates flat, horizontal, vertical position. 2 indicates flat, horizontal position. 4 indicates flat, horizontal, vertically downward position. The number 8 gives you information about the type of coating and current used.

What do the letters on electrodes mean?

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.

How do you read welding electrode codes?

The letter “E” indicates an electrode. The first two digits represent the resulting weld’s minimum tensile strength, measured in pounds per square inch (psi). For example, the number 70 in a E7018 electrode indicates that the electrode will produce a weld bead with a minimum tensile strength of 70,000 psi.

How are electrodes classified?

The welding electrodes are classified on the basis of the electrode metal, flux coating, current used, position of welding, performance characteristics, chemistry and the mechanical properties of the weld metal etc.

What is electrode classification?

Electrodes are manufactured for different purposes and welding types and are classified by a five-digit number like E7011-M. Each number and letter corresponds with a piece of information, including recommended welding position, tensile strength and penetration depth. The “E” in the classification stands for electrode.

What is C3 in electrode?

E8018-C3 welding electrode is designed for 1% nickel applications as well as 80,000 (psi) tensile strength applications. These electrodes provide excellent puddle control with good wetting action and tie in, have good arc characteristics and easy slag removal.

How many electrode sizes are there?

Common electrodes used in Stick welding are 6010, 6011, 6013, 7018 and 7024 with the most common diameters ranging from 1/8- to 5/32-in.
