This committee put in the form work for the first edition of the ASME Boiler Code - Rules for the Asme section viii division 1 of Stationary Boilers and for the Allowable Working Pressures, which was issued in and published in As a result, the state of Massachusetts enacted the first legal code based on ASME's rules for the asme section viii division 1 of steam viiii in Asme section viii division 1 Asme section viii division 1 Asme section viii division 1 The components and supports covered by section III are intended to be installed in a nuclear power system that serves the purpose of producing and controlling the output of thermal energy from nuclear fuel and those associated systems essential to safety of nuclear power asme section viii division 1.
The specifications contained in this Part specify the mechanical properties, heat treatment, heat and product chemical composition and analysis, test specimens, and methodologies of testing. See our and for details. Asme section viii division 1 See our and for details. It provides material specifications for nonferrous materials which are suitable for use in the construction of pressure vessels.
The designation asme section viii division 1 the specifications start with 'SA' and a number which is taken from the ASTM 'A' specifications. Clipping is a handy way to collect important slides you want to go back to later.
Updated July 30 , Page 10 of Auditing of Welding Under ASME Section IX When preheating is anticipated, the methods and equipment used for maintaining minimum preheat temperature during welding should be examined for adequacy of heating capacity.
The availability of tools pyrometer, crayons, etc. Whether or not personnel know how to use them should be demonstrated. The auditor should use his judgment when the likelihood of exceeding an interpass temperature limit is not likely e. Any welding done by machine or automatic methods should have volt and ammeters or wire feed speed meters that are periodically checked for accuracy. Other methods for checking wire feed speed may be used in lieu of meters, but welders should be able to demonstrate that they know how to use them.
Welding leads and connections should be tight since loose connections will affect arc voltage. The supervision of the welder should be reviewed. If the welder actually has the WPS in his work package, his depth of understanding of the WPS and other documents related to proper Code construction should be established. If he receives direction from his foreman, the foreman's sources and the foreman's depth of understanding of the WPS and other related documents should be established, and the accuracy of the information passed to the welder should be checked.
That the welder actually does what is required by the WPS and other fabrication documents should be verified.
For each welder or operator who welded on selected welds, qualifications should be reviewed against the variables in QW or QW as applicable. Once proper qualification as required by Section IX has been established, the conditions in the Range Qualified column should be compared against what the welder actually did in production.
The following are a some commonly missed items against which welders qualifications should be compared: Welders should only have welded using the process es for which they are qualified.
When checking any welder who welds on pipe or makes a nozzle weld, the diameter for which he qualified should be checked against the diameter of the welds that he made in production.
Welders who qualify using gas backing must use gas backing during production welding, even though the materials on which they may be welding do not normally require use of gas backing.
Welders who qualify using GMAW spray, globular or pulsed welding may not use short circuiting transfer welding and vice-versa. Welders who qualify using E F-No. Welders who qualify using GTAW in combination with some other process may not make welds using the other process unless that welding is done on backing. Updated July 30 , Page 11 of Auditing of Welding Under ASME Section IX If any bend test specimens are available, they should be examined, paying particular attention to the fact that the radius of the bend is normally 2 times the test specimen thickness, i.
The inspector, the welder's supervisor and the welder should be asked how they know what each welder is qualified to do -- that information does no good stuffed away in QC files; it has to be provided to those who will supervise the welders.
Summary of Part 2 Part 2 of this document lists what auditors should look at when reviewing the welding aspects of a shop for a Code stamp. Reviewing the competence of a shop's welding practices in the depth described above requires a reasonable level of knowledge in welding, including reasonable understanding of what Section IX and the applicable Construction Codes require related to welding. There are more ways of entering data on these records than are shown below.
The data entered in the Actual Values column can be different from that shown below as long as they accurately describe what the welder did when the welded the test coupon. The data entered in the Range Qualified column is based on what is in the Actual Values column as applied to the specific variable. The range qualified can be more restrictive than what is permitted by Section IX. The paragraph numbers correspond to the numbers on the lines on Form QWA.
When completing the Testing Conditions and Qualification Limits section, the general guidance is in the format: If you put this in the Actual Values column, this is what goes in the Range Qualified column. Sentences in italics are the references to the applicable paragraphs in Section IX that address the item. Enter the Name of the Welder who has been tested. See QW Enter the Number s , Letter s or Symbol s that the Welder has been assigned to identify his or her work.
See QW, second paragraph. Mark this box if the test was given on a test coupon. Mark this box if the test was given using a production weld. Enter the Specification, type and grade of the base metal s which made up the test coupon.
Enter the thickness of the base metal. It is customary to enter the nominal thickness; however one may measure and record the actual thickness if desired. Enter the Welding Process or Processes that the Welder used to weld the test coupon.
Continue this practice for other variables that might be different for different processes or other variables used in the same test coupon. Enter the same process es in this space as was entered in space 9.
Enter the Welding Process Type. A person who qualifies using manual or semi-automatic welding is a Welder. A person who qualifies using machine or automatic welding is an operator, and Form QWB should be completed instead of this form. Separate qualifications i. Enter the same type of welding in this space as was entered in space If the welder will use both manual and semi-automatic GTAW, both types of welding maybe entered i.
Manual, Semi-auto. Enter the P-number s of the one material making up the test coupon. If either material does not have a P-number, see QW If there is no way to assign the base metal a P-number under the provisions of these paragraphs, write down the specification and grade of the test coupon material -- and write small.
Enter the P-number s of the other material making up the test coupon. See Enter the P-number or the range of P-numbers of the materials that is qualified by the test coupon per QW If unclassified materials are to be welded, examine the right-hand column of QW If there is no way to assign the base metal a P-number, write down the specification and grade of the test coupon material shown in steps 12 and Mark this box if the test coupon is plate.
Mark this box if the test coupon is pipe, tube or other hollow product form. Enter the nominal thickness of the test coupon base metal s. Measured thickness may also be entered, but the fact that the thickness was measured should be noted since this practice is nonstandard.
When using pipe, enter the pipe size NPS or outside diameter. When using tube or other hollow shape, enter the outside diameter OD of the material. Enter the minimum outside diameter qualified based on QW Use QW Enter over 24 in. OD if the coupon was plate. OD if welding is done in the flat position. This not customarily entered on the qualification record except if the qualification is limited to the flat position. Also see QW If OFW, enter the thickness of the test coupon.
Enter the type of backing used. Backing can be a backing strip, nonfusing metal backing e. A weld made from two sides of a groove is considered welding on backing, as is a fillet weld test.
Potential entries are None, Used, Weld metal, welded both sides. If more than one process or variation of process is used See QW , it must be recorded that backing was used for the subsequent processes or variations of process. If backing was used in space 20, enter Required. If backing was not used, enter Optional. If the welding process was OFW, it is the opposite.
Enter the specification e. SFA 5. If the weld was made without the addition of filler metal, enter None. Enter the Classification e. E of the electrode or filler metal that was used. Enter the Fnumber of the filler metal. The F-number depends on the welding process and electrode or filler metal that was used. Enter the Fnumber or range of Fnumber filler metals that the welder is qualified to use. If solid or metal cored was recorded in space 26, enter solid, metal cored in this space.
If flux cored was recorded in space 26, enter flux cored in this space. If a consumable insert was used in the root pass, enter Used; If an insert was not used, enter None. If an insert was used during the qualification test, enter Required. If no insert was used, enter Not Permitted. Enter the approximate deposit thickness for each welding process, each F-number and for each set of essential variables.
That is, if more than one process or variation on a process is used e. If you are using the Section IX form, follow these instructions for the lines following Deposit thickness.
Enter the deposit thickness for each process and variation as above. If the welder used 3 or more passes with a process, check "Yes" for that process. Enter the maximum thickness of weld metal that the welder is qualified to deposit for each process, electrode type or set of essential variables. Also note that QW may permit F-1 through F-4 electrodes other than the F-number that was used on the test coupon.
Enter the position in which the test coupon was welded. These are 1G, 3G, 6G, 3F, etc. See QW, QW for definitions of testing positions. These paragraphs lead to QW Enter the welding positions in which the welder may weld. See QW which leads to figures QW Enter nothing or enter "NA" if welding was done in any other position.
Enter the same data Uphill or Downhill or nothing [or enter "NA"] as in space Welders are generally limited to welding in the progression in which they test. Although QW Enter Used if backing gas was used. Enter None if no gas backing was used. If gas backing was used, enter Required. If gas backing was not used, enter Optional.
If space 36 is blank or "NA" , enter nothing or "NA" , as appropriate. It should be noted that, if qualification was done on backing and no backing gas was used, optional or with and without are correct entries in this space since the welder is qualified to weld with and without backing gas. This is somewhat strange since backing gas is not normally used when welding on backing except for PI, P through P53 and P metals; however, recording the fact that backing gas is optional documents the range qualified properly.
FCAW transfer mode is either Spray or Globular unless it is was used for open root welding, in which case it is shortcircuting.
Enter Short Circuiting S if short-circuiting was entered in space Enter the same data in this space as is in space Enter Acceptable for the results of visual examination of the completed test coupon.
Visual examination of the coupon is required for coupons that will be mechanically tested and is recommended for those that will be radiographed. See QW and QW Record the date that the test coupon was welded.
See QW for preparation of bend test specimens. If bend tests were performed and the bend test specimens were transverse root and face bends, check this box. If bend tests were performed and the bend test specimens were longitudinal root and face bends, check this box. Face and root bends are required for all test coupon thicknesses.
If bend tests were performed and the bend test specimens were side bends, check this box. Enter the type of bend specimen i. Enter the results of each bend specimen. All results such as "Acceptable," OK or similar word must indicate that each specimen was or was not acceptable. The results may describe in detail the extent of discontinuities found e. If the test coupon was volumetrically examined instead of mechanically tested, enter the test method and the results.
All results must indicate that each coupon was or was not acceptable. It is good practice to attach the test laboratory's report to the qualification record. It is not smart to keep radiographs since they are always subject to deterioration and to reinterpretation by others at a later date.
Note that at least 6 inches of weld length are required to be examined. Enter the identification number assigned by the testing lab if a lab was used. If radiographic reader sheets are identified by a lab number or similar unique identifier, enter that identification. Enter the results of the fillet weld fracture test, if fillet weld tests are conducted. Enter the length and percent of defects found during the fracture test, if fillet weld tests are conducted. Enter the results of the fillet weld macro fusion test, if fillet weld tests are conducted.
Enter the size of the fillet weld legs from the fillet weld macro fusion test, if fillet weld tests are conducted. Enter the measured concavity or convexity from the fillet weld macro fusion test if fillet weld tests are conducted.
Enter the description and results of any other testing that was done. Enter the name and title of the individual who evaluated the mechanical or volumetric tests. Persons who evaluate bend test coupons shall determine that the bend test specimens have been prepared in accordance with QW and that they were bent around the correct radius per QW and QW Enter employing company of the individual who evaluated the mechanical or radiographic tests.
Enter the name and title of the individual who supervised the actual welding of the test coupon. This person must be an employee who works for the company that is qualifying the welder. This person does not have to witness welding of the entire test coupon, but he should see enough to verify that the data that will be recorded on the qualification record form is an accurate record of what the welder actually did.
Enter employing company of the individual who supervised the welding of the test coupon. This should be the same company name as is shown in space Enter the name of the company that is qualifying the welder or operator.
Signature and title of the individual certifying the qualification record of the welder or operator for the qualifying organization.
This does not need to be the same individual as entered in space Date of certification. This date will usually be sometime after the date of the test shown in space If qualification records are ever reformatted, the test date should remain unchanged and the certification date space 43 should be the actual date of certification. Reply 1 : Yes. QW Question 1 : Is omission of an essential, nonessential or supplementary essential variable from a WPS interpreted to be a negative response for that variable?
Reply 1 : No. Reply: The format of the WPS may be any which will fulfill the needs of the stamp holder: a single document, a series of documents properly referenced together.
The WPS, regardless of the format selected, shall include all essential. Reply: Form shown in QW is a suggested format for the required information; a WPS may be presented in any form as long as every essential and nonessential variable covered by QW through QW is presented. Any additional information is not required but may be attached to the WPS at the option of the manufacturer.
Reply l : No. Voltage and amperage ranges may be recorded within the limits of a narrow range, rather than the full range of the variables allowed.
Question 2 : QW A manufacturer may include all additional variables he may consider helpful such as the nonessential variables, but is only required to record the essential variables used. Does this permit the manufacturer to leave the PQR blank where nonessential variables are concerned or to fill in the nonessential variables in any manner considered to be helpful at the manufacturer's option?
Reply 2 : A manufacturer is only required to list the essential variables on the PQR; any further information may be included at his option. Reply 3 : No. Reply: No. Interpretation Background: QW A procedure qualification test was conducted using the SAW process without the use of supplemental filler metal. The method of recording information on the PQR and WPS may be by statement, sketch or other means as long as the essential variables are addressed.
