The Classification of Welding Electrodes "What do all the numbers refer to that are printed on electrodes?" The Layman might be puzzled by the array of letters and numbers that are printed on the end of welding electrodes. They are there to classify the type of electrode. Most of the welding rods will use the AWS system which stands for
The two MMA electrode classification schemes that will be dealt with in this month's article are the EN (Euronorm) and the AWS (American Welding Society) specifications. There is insufficient space to cover in detail the whole range of compositions for MMA electrodes so the emphasis here will be on the carbon steel filler metals.
