Lesson 10 - Reliability of Welding Filler Metals

© COPYRIGHT 2000 THE ESAB GROUP, INC. LESSON X 10.7 MILITARY SPECIFICATIONS Military specifications are issued by the Department of Defense and it is mandatory that all work performed for that department be covered by the applicable military specification. Military specifications are identified by a letter-number designation and the title. An ex- ample is: MIL-E-22200/1E - Electrodes, Welding , Mineral Covered, Iron Powder, Low Hydrogen, Medium and High Tensile Strength, As-Welded or Stress Relieved Applications. 10.7.0.1 In the example, MIL designates that it is a Military specification. The first letter E stands for Electrode which is the significant word in the title. The number 22200/1 is the serial number of the specification; the letter E at the end designates the revision letter and will change as further revisions are made. The underlined portion is the title of the specifi- cation. 10.7.0.2 A Military specification may cover only one or a number of electrodes or wires. When the specification includes more than one item, a “type” designation is necessary. As an example, an E8018-C3 low alloy electrode would be designated as MIL-E-22200/1E, MIL 8018-C3. 10.7.0.3 The following is a partial list, along with a brief description, of the more common military electrode specifications currently in use.
