Please note that these forums are intended for the discussion of and answering of questions beyond the everyday; everyday questions which have easily located answers in many reference books, or through online sources.

Many excellent references on welding have this information. If you have additional questions beyond what these references have, please ask.

Dear Abdul Halim Galala, Salama't Your deciphering of codes on electrodes is correct except that E is not for electric. It is for Extruding. Flux coating of electrodes is done by two methods: 1) Extruding of wire through semi-dried flux and 2nd) Dipping of wire in semi-liquid flux and dried after. Please refer to page 25, Chapter - Kind of Electrodes, Arc Welding - Book written by Members of Philips Welding Department, Edited by F.J. Bakker & A.J.W. Hovestreijdt, Year Published 1964. Hope you would accept this correction.

Can't follow your logic here. I thought E was electrode. Following your logic we'd have both E and D for extruded and dipped flux application.

I think I'll stick with E=electrode.

The book you are referring to is largely obsolete. The AWS standards listed previously are the standards used by the world.

Your deciphering of codes on electrodes is correct except that E is not for electric.

Dear AbdulWasay, the figure at my post #3 is correct which extracted from HOBART Catalogue, and the following figure is extracted from ASME Section II, Part C (SFA-5.1):
