'Backing' for approval of welding procedures

For welding procedure qualification, some welding codes classify the use of backing as an essential variable (EN 15614-1) but others classify it as non-essential (ASME Section IX). For welder qualification, backing is invariably classed as an essential variable. This is because being able to produce a sound weld root using backing does not 1501 - E118 - Welding Technology and Codes - 07 - QW-404.4 The welding wire was ER80S-D2 for GTAW and ER70S-6 for GMAW ASME Section II, SFA 5.28 specifies low -alloy steel electrodes for gas shielded arc welding ASME Section II, SFA 5.18 specifies carbon steel electrodes for gas shielded arc welding Table QW-432 Paragraph
