This allows an electrode to be used right away, without having to wait potentially years for the filler metal specification to be revised to create a new usability designation. The intent for the general designation is to allow newly developed flux-cored electrodes that may differ in one way or another to all the other usability designations a way to still be classified according to the filler metal specification. In both cases, it is general because not all of the particular requirements specified for the other designation classifications are specified for this classification. “GS” stands for general, “single” pass only applications. The “G” stands for “general” classification. Complete details about these electrode classification numbers and more are contained in the AWS document A5.20/A5.20M:2005, titled “Specification for Carbon Steel Electrodes for Flux Cored Arc Welding”.įigure 1: Key to AWS Classification Designators for Carbon Steel Flux-Cored ElectrodesĪs stated earlier, the usability designators for flux-cored electrodes specify the requirements for polarity and general operating characteristics. These designators may be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, G or GS. Each usability designation indicates a general grouping of electrodes that contain similar usability characteristics. The exceptions are the “G” and “GS” classifications, where usability characteristics may differ between similarly classified electrodes. Each letter and digit in the number indicates something about the electrode. Figure 1 shows the key to an electrode’s AWS classification number. Before discussing the specifics of each designator, a quick review of the meaning of an electrode’s entire American Welding Society (AWS) classification number is in order. I have heard these “dash numbers” called performance capabilities numbers. But what exactly do they mean? Also, how can some wires have more than one AWS number?Ī: The dash numbers you are asking about are called “Usability Designators” and refer to the usability of the electrode with requirements for polarity and general operating characteristics. Some example numbers are E71T-1, E71T-8, E71T-9, E71T-11, etc. Some wires even have two or three numbers on them. I have noticed that the AWS classification number for many of the flux-cored wires we carry are the same on the front end, but then have different dash numbers on the back end.

Trade terms: FOB, CFR, CIF, Loading Port: Xingang, Tianjin, Chinaĭelivery Detail: Within 15 days after confirmation Payment terms: 100% LC at sight or 30% TT in advance balance against copy of BL. Our advantages is stable arc, little spatter, less smoke higher deposition efficiency excellent welding performance easy restrike.

Most widely used for welding some key structures like shipbuilding, mechanical manufacture, pressure vessels, boilers, petroleum machinery, chemical machinery, hoisting machinery etc. Flux Cored Arc Welding Wire (FCAW), is used for welding structures made of carbon steel and low-alloy structural steel with tensile strength higher than or equal to 490MPa.
