SOCIETY NEWS ISO/DIS 9455-13, Soft soldering fluxes — Test methods — Part 13: Determination of flux spattering. Revised Standard Approved by ANSI A5.36/A5.36M-2016, Specification for Carbon and Low-Alloy Steel Flux Cored Electrodes for Flux Cored Arc Welding and Metal Cored Electrodes for Gas Metal Arc Welding. Approval Date: 5/6/2016. Reaffirmed Standard Approved by ANSI A5.15-1990 (R2016), Specification for Welding Electrodes and Rods for Cast Iron. Approval Date: 5/4/2016. Interpretations D1.1 Subject: Waveform Power Supplies Code Edition: D1:1:2015 Code Provision: Subclauses 5.10, 3.2.1, and 3.2.4 AWS Log: D1.1-15-I01 Inquiry: 1) Does AWS D1.1:2015, clause 5.10 preclude the use of “waveform” power supplies? 2) Does AWS D1.1:2015, clause 5.10 preclude the use of “waveform” power supplies where the welding procedure is preprogrammed into the welding machine, and the welding personnel call up the welding procedure from the welding machine’s memory? 3) Does AWS D1.1:2015, clause 3.2.1 preclude the use of GMAW-P from use with prequalified WPSs? 4) Does AWS D1.1:2015, clause 3.2.4 preclude the use of waveformcontrolled power supplies from being used with prequalified WPSs? 5) Does AWS D1.1:2015, clause 3 permit the use of prequalified WPSs that use GMAW-P? Response: 1) No. Any type of power supply is acceptable, providing the equipment is “…so designed and manufactured...as to enable designated personnel to follow the procedures and attain the results described elsewhere in this code.” 2) No. Any type of power supply control is acceptable, so long as the controls are such that designated personnel are enabled to “...follow the procedures and attain the results described elsewhere in this code.” The individuals 74 WELDING JOURNAL / JULY 2016 responsible for the WPSs should make certain that the stored WPSs meet the applicable requirements of D1.1, including compliance with D1.1:2015, clause 5.3.1.2. 3) No. Clause 3.2.1 permits the use of all modes of GMAW, except for GMAW-S, which is precluded from prequalification. 4) No. Clause 3.2.4 was developed to preclude the use of constant current power supplies for FCAW and GMAW when using prequalified WPSs; this provision was developed without any intention of imposing requirements on GMAW-P. 5) Yes, providing all the requirements of Clause 3 are met. Subject: Waveform Power Supplies Code Edition: D1:1:2010 Code Provision: Subclauses 5.11, 3.2.1, and 3.2.4 AWS Log: D1.1-10-I21 Inquiry: 1) Does AWS D1.1:2010, clause 5.11 preclude the use of “waveform” power supplies? 2) Does AWS D1.1:2010, clause 5.11 preclude the use of “waveform” power supplies where the welding procedure is preprogrammed into the welding machine, and the welding personnel call up the welding procedure from the welding machine’s memory? 3) Does AWS D1.1:2010, clause 3.2.1 preclude the use of GMAW-P from use with prequalified WPSs? 4) Does AWS D1.1:2010, clause 3.2.4 preclude the use of waveformcontrolled power supplies from being used with prequalified WPSs? 5) Does AWS D1.1:2010, clause 3 permit the use of prequalified WPSs that use GMAW-P?

A3.0M/A3.0:2010 Subject: Definition for Heat Input Code Edition: A3.0M/A3.0:2010 Code Provision: Glossary AWS Log: A3.0-10-I02 Inquiry: Can you please clarify whether this definition refers to the total energy of the arc applied to the workpiece during welding, or does it refer only to the amount of heat actually absorbed into the workpieces during welding (the total energy of the arc minus the heat losses)? Interpretation: The definition refers to the input energy applied to the workpiece during welding. There is no attempt to differentiate the amount of energy absorbed, reflected, miscalculated, misdirected, lost, etc. as this is considered beyond the scope of the definition. It is important to realize that this definition applies to all types of welding processes, not just arc welding. Errata The following Errata have been identified for AWS D1.1/D1.1M:2000, Structural Welding Code — Steel. Pages 80, 83, Figure 3.4, Detail BU3a S, B-U5b and TC-U5a. Change “3 X R” to “1⁄8 X R” and “6 X R” to “1⁄4 X R”. Pages 139, 141, Table 4.9, under (1) Test on Plate, Type of Test Weld (Applicable Figures): Change “Groove (Fig. 4.30 or 4.31)” for 3⁄8 < T < 1 to “Groove (Fig. 4.21, 4.22 or 4.29).” Page 176, Table 6.1 under “(6) Undersized welds.” Change “In all cases, the undersize portion of the shall…” to “In all cases, the undersize portion of the weld shall…” Page 226, Clause 7.5.5.7, change reference to subclause 6.6.1 to subclause 6.9.
