used to develop SI equivalents: (a) SI units are placed in parentheses after the U.S Customary units in the text (b) In general, separate SI tables are provided if interpolation is expected The table designation (e.g., table number) is the same for both the U.S Customary and SI tables, with the addition of suffix “ M ” to the designator for the SI table, if a separate table is provided In the text, references to a table use only the primary table number (i.e., without the “ M ” ) For some small tables, where interpolation is not required, SI units are placed in parentheses after the U.S Customary unit (c) Separate SI versions of graphical information (charts) are provided, except that if both axes are dimensionless, a single figure (chart) is used (d) In most cases, conversions of units in the text were done using hard SI conversion practices, with some soft conversions on a case ‐ by‐ case basis, as appropriate This was implemented by rounding the SI values to the number of significant figures of implied precision in the existing U.S Customary units For example, 3,000 psi has an implied precision of one significant figure Therefore, the co n ve rs i o n to S I u ni ts wo u l d typ i cal l y b e to 20 000 kPa This is a difference of about 3% from the “ exact” or soft conversion of 20 684.27 kPa However, the precision of the conversion was determined by the Committee on

and tensile strength, elastic modulus) were generally converted to MPa to three significant figures See example in the following table: Areas in square inches (in ) were converted to square millimeters (mm ) and areas in square feet (ft2 ) were converted to square meters (m ) See examples in the following table: in in 10 in ft2 in in 10 in ft3 Pressure (U.S Customary) 0.5 psi psi psi 10

always be in MPa for calculations, there are cases where other units are used in the text For example, kPa is used for small pressures Also, rounding was to one significant figure (two at the most) in most cases See examples in the following table (Note that 14.7 psi converts to 101 kPa, while 15 psi converts to 100 kPa While this may seem at first glance to be an anomaly, it is consistent with the rounding philosophy.)

is displayed BACKG ROU N D Advances in microprocessor controls and welding power source technology have resulted in the ability to develop waveforms for welding that improve the control of droplet shape, penetration, bead shape and wetting Some welding characteristics that were previously controlled by the welder or welding operator are controlled by software or firmware internal to the power source It is recognized that the use of controlled waveforms in welding can result in improvements in productivity and quality The intention of this Code is to enable their use with both new and existing procedure qualifications The ASME Section IX heat input measurement methods in QW-409.1(a) and QW-409.1(b), were developed at a time when welding power source output was relatively constant The heat input of welds made using waveform controlled power sources is not accurately represented by QW-409.1(a) due to the rapidly-changing outputs, phase shifts, and synergic changes, but is correctly represented by QW-409.1(b) or QW-409.1(c) During waveform controlled welding, current and voltage and values observed on the equipment meters no longer are valid for heat input determination, and must be replaced by instantaneous energy (joules) or power (joules/second or watts) to correctly calculate heat input QW-409.1(c) more accurately reflects heat input changes when performing waveform controlled welding, but is also suitable for nonwaveform controlled (conventional) welding ð 17Þ H -2 00 WAVEFORM CON TROLLED WELDI N G AN D H EAT I N PU T DETERM I N ATI ON Power sources that support rapidly pulsing processes (e.g., GMAW-P) are the most common waveform controlled power sources Power sources that are marketed as synergic, programmable, or microprocessor

provided they are amended to require heat input determination for production welds using the methods of QW-409.1(c) Welding procedures previously qualified using nonwaveform controlled welding and

organization, as needed to understand how to properly set up and adj ust the equipment for welding and conformance to the WPS requirements Power sources capable of waveform controlled welding often have additional operator settings that are typically not used during nonwaveform controlled welding It is important for a welder to be familiar with other equipment parameters that can influence the overall welding performance These can include the mode, arc control, program, cable length, wire feed speed, trim, and other machine and software settings 346 ASME BPVC.IX-2017 M AN DATORY APPEN DI X

RPOSE ASME Section IX provides rules for the qualification of welding, brazing, and fusing personnel and the procedures that they follow in welding, brazing and fusing While the historical application of Section IX has been in service to the ASME Boiler and Pressure Vessel Code and the ASME B31 Codes for Pressure Piping, Section IX is invoked by many other standards without the benefit of members of the Section IX Committee participating in those committees In addition, Section IX is invoked in specifications and related contract documents The purpose of this Nonmandatory Appendix is to provide guidance on invoking Section IX in other documents in a clear, concise, and accurate manner K-2 00 SCOPE OF SECTI ON I X AN D WH AT REFEREN CI N G DOCU M EN TS M U ST ADDRESS Section IX addresses only the mandatory content of welding, brazing, and fusing procedures; the qualification of those procedures; and the qualification of personnel who follow those procedures in the manufacture, fabrication, assembly, and installation of welded, brazed, and fused products Accordingly, to ensure construction of suitable products, the requirements for the service conditions, materials used, the design of j oints, preheating, postweld heat treatment (PWHT) , metallurgical effects of welding, acceptance criteria for weld quality, and related examinations must be addressed in the Codes, standards, specifications, or contract documents that invoke Section IX K-300 RECOM M EN DED WORDI N G G EN ERAL — When invoking Section I X in general, the following wording is recommended: “ Welding, brazing, and fusing shall be performed using procedures and personnel qualified in accordance with the requirements of ASME BPVC Section IX.” When the above is specified, qualification for the following are automatically included: (a) all welding processes that are listed in QW-250 for groove and fillet welding (b) use of standard welding procedures specifications (SWPSs) listed in Mandatory Appendix E (c) ap p l icatio n o f hard- faci ng weld metal o verlay (hardness values shall be a matter of agreement between the supplier and the purchaser) (d) application of corrosion-resistant weld metal overlay (chemical composition of the weld overlay surface shall be a matter of agreement between the supplier and the purchaser) (e) laser beam lap joints Further, construction codes may specify different requirements than those specified by Section IX; for example, ASM E Section I I I has requirements fo r PWH T o f procedure qualification test coupons that are more restrictive than those of Section IX, and ASME B31.1 allows organizations to use welding procedure specifications (WPSs) qualified by a technically competent group or agency, whereas Section IX requires each organization to qualify WPSs themselves When such requirements are specified in the referencing construction Codes that 348 ASME BPVC.IX-2017 (f) joining of composite (clad) materials

of the organization I N TRODU CTI ON When a welder or a welding operator welds a test coupon or makes a production weld, that person does not weld one way when the applicable standard is ASM E and another way when the applicable standard is AWS, EN, JIS, or ISO Recognizing this, recent revisions by ISO TC44, to ISO 9606-1, and ISO 14732 bring them much closer to the requirements of Section IX This Appendix discus s es what is neces s ary fo r an o rganizatio n that is testing welders or welding operators under the above ISO standards to also certify that those welders and welding operators

requirements of Section IX (c) Radiographic and ultrasonic examination acceptance criteria satisfying the requirements of ISO 9606-1 or ISO 473 also satisfy the requirements of Section IX, except that indications characterized as linear slag may not exceed the thickness of the test coupon divided by (i.e., the flaw length may not exceed t /3); this is more restrictive than ISO 581 7, quality level B, which allows elongated slag inclusions to be equal in length to the thickness of the test coupon (d) When using the ultrasonic test method, the test coupon must be 1/4 in (6 mm) thick or thicker (e) Test coupons tested by fracture test according to ISO 9017 not satisfy the requirements of Section IX The following nontechnical requirements must be met: (a) When a welder or welding operator is tested, the WPS followed during the test must be a WPS qualified to Section IX (b) Welding of the test coupon must be done under the full supervision and control of the organization that will employ that welder or welding operator; this may not be delegated to another organization (c) Testing of test coupon may be performed by others, but the qualifying organization is responsible for ensuring that work performed by others is in compliance with the requirements of Section IX (d) The completed qualification record must be certified by signature or other means described in the organization ’
