ASME BPVC-2015 SET
The purpose of this guide is to correlate the electrode and rod classifications with their intended applications so the specification can be used effectively. Reference to appropriate base metal specifications is made whenever asme bpvc 2015 set that can be done and when it would be helpful. Such references are intended only as examples rather than com- plete listings of the materials for which each filler metal is suitable.
A2. Classification System
A2.2 The prefix "E" designates an electrode as in other specifications. The letters "ER" indicate that the filler metal may be used either as an electrode or a rod. For A5.28, the number 70, for example, indicates the required minimum tensile strength, as a multiple of 1000 psi, of the weld metal in a test weld made in accordance with specification A5.28. Similarly, for A5.28M, the number 49, for example, indicates the required minimum tensile strength, as a multi-ple of 10 MPa, of the weld metal in a test weld made in accordance with specification A5.28M. The letter "S" designates a solid electrode or rod. The letter "C" designates a composite electrode The suffix following the hyphen indicates the chemical asme bpvc 2015 set compo- sition of the filler metal itself, in the case of solid electrodes and rods, or the weld metal under certain specified test conditions, in the case of composite stranded or metal cored electrodes. Optional designators are also used in this specification in order to identify electrodes and rods that have met man- datory classification requirements and cert
Table 10. Package forms, sizes, and weights other than these shall be as agreed between purchaser and supplier. 18.2 The liners in coils with support shall be designed and constructed to prevent distortion of the coil during normal handling and use and shall be clean and dry enough to maintain the cleanliness of the filler metal. 18.3 Spools shall be designed and constructed to pre- vent distortion of the filler metal during normal handling and use and shall be clean and dry enough to maintain the cleanliness of the filler metal. Standard spools are shown in Figs. 4A and 4B.
19. Winding Requirements
19.1 Electrodes on spools and in coils (including drums and reels) shall be wound so that kinks, waves, sharp bends, overlapping or wedging are not encountered, leaving the
Standard Sizesfiller metal free to unwind without restriction. The outside Standard sizes for icc 2015 electrodes and rods in the different package forms [straight lengths, coils with support, coils without support, drums, and spools (see Section 18, Stan- dard Package Forms)] are as shown in Table 9.
17. Finish and Uniformity
17.1 All electrodes and rods shall have a smooth finish which is free from slivers, depressions, scratches, scale, seams, laps (exclusive of the longitudinal joint in composite metal cored electrodes), nfpa 2015 and foreign matter that would adversely affect the welding characteristics, the operation of the welding equipment, or the properties of the weld metal.
