Welding Rod Number Meaning ~ In this example its the American Welding Society numbering system. This can be found in ASME BPVC Section IX Table QW-442. The E7018 welding rod is one of the several electrode types with AWS designation. Measured in thousands of pounds per square inch. As a result the higher the number the stronger the electrode. Measured in thousands of pounds per square inch. The first two numbers of 7018 correspond to the tensile strength or the stress-bearing capability of the weld bead. A number grouping has been done on the basis of the chemical composition of the deposited weld metal. This value may or may not appear printed on the consumable. Once you understand the numbering system you can learn a lot about the rod. Indeed lately is being hunted by consumers around us, perhaps one of you personally. Individuals now are accustomed to using the internet in gadgets to view video and image information for inspiration, and according to the name of this post I will discuss about Welding Rod Number Meaning. Thus the welding current and open circuit voltage OCV are symbolised by a digit as given below corresponding to the characteristics of the welding power source PS required in order to ensure working conditions free of arc instability or interruptions. See Classification Table above X Indicates what alloys are in this electrode. The E7018 welding rod is one of the several electrode types with AWS designation. See Suffix Table page 45. E represents an electrode which means an electrical current causes the filler material to be deposited. The next to last digit indicates position. So this number is the tensile strength of the material the weld you will create with the rod. The number 1 indicates an All-position electrode. The electrode is made up of materials which are similar to that of the metals chosen to be welded. The AWS assigns four or five digits after the letter.
Lets use the good old E6011 arc welding electrode as an example. Thus the welding current and open circuit voltage OCV are symbolised by a digit as given below corresponding to the characteristics of the welding power source PS required in order to ensure working conditions free of arc instability or interruptions. The numbers are a code that describes various attributes of the rod.
Another type of grouping for filler metal or welding rod is the A Number.
2 is better for flat horizontal welding. This value may or may not appear printed on the consumable. So this number is the tensile strength of the material the weld you will create with the rod. The first two numbers of 7018 correspond to the tensile strength or the stress-bearing capability of the weld bead.
