![]() The most common versions of the dash are the en dash (–) and the em dash (-) that is located in between the letter, and the last number of the specific FCAW Electrode type when reading it, starting from left to right is the key to proper interpretation of what the letter "G" is representing and therefore, critical to observe upon attempting to give the correct answer of the question as it is typed originally in the first post of this thread. It is longer than a hyphen and is used differently. the placement of the letter "G" without the horizontal line (Punctuation mark.). The difference between a "totally" correct answer in this post as opposed to a "halfway correct answer" which is equivalent to "almost" which never end up being correct, is a simple "misread" on the part of the person's attempting to answer the question in the correct manner. I agree with you, and I was waiting for you to point out exactly why but, I guess I'll have to get technical here. The letter G indicates that the chemical composition is not specified." Hope that clears everything up, Regards, Shane ![]() The G indicates that the slag system and shielding gas are not specified." E81T1-G "Designates the chemical composition of the deposited weld metal. Let's clarify SFA 5.20 first Mandatory Classification Designators E71T-G "The designator is some number from 1 through 14 or the letter "G" with or without an "S" following.The "G" indicates that the external shielding, polarity, and impact properties are not specified.The "S" indicates that the electrode is suitable for a weld consisting of a single pass." (This does not mean that "G" is only multipass, it can also be single pass as well) SFA 5.29 is the Specification for Low Alloy Steel Electrodes for Flux-Cored Arc Welding Mandatory Classification Designators E81TG-XX "This designator will be some number:1, 4, 5, 6, 7, 8, 11, or the letter G. The reasons for this confusion are that SFA 5.20 and SFA 5.29 have different meanings for the "G" and even in SFA 5.29 the "G" can be found in two different positions and means two different things. Hello all, Some interesting answers but the only one who answered kenwelds question correctly is magodley. So you have a FCAW wire of 80,000 lb strength with tubular core good for welding in all positions that requires a shielding gas such as 75/25 CO2/Ar or 100%CO2 and is rated as a multiple pass filler. The additional suffix of a 'G' or 'GS' following the rest of your number indicate either a multiple pass electrode (G) or a single-pass electrode (GS). #'s 1, 2, 5, 9, & 12 require additional shielding, as in an external gas shield. #'s 3, 4, 6, 7, 8, 10, 11, 13, & 14 need no additional shielding other than what is in the electrode. With FCAW rather the process is '-G' or '-S' (defined by sws) the break down goes like this" E= Electrode, the wire is the electrode First 'X' in your case '8'= 80,000 lbs tensile strength of deposited weld metal Second 'X' in your case '1'= any position capability of operation, as opposed to '0' which is Horizontal and Flat only T= Tubular electrode, has a flux core through the center of the wire The suffix behind your 'T' (the '1' not shown in my EXXT-X) is a suffix having to do with other formulations and characteristics. To all involved thus far, especially Kenweld (WELCOOME to the forum by the way, at least you have not posted many times and I don't recall seeing you before), EXXT-X: Now, magodley is right.
