Reliable welding and brazing materials are required to produce sound joints using one of the many welding and brazing processes available. These are the welding ller metal specications of the AWS [2] adopted for use by the ASME. In this respect, asme section ii part b pdf free download, Section II, Part C is comparable to Sections II, Parts A and B that contain the ASTM Material Specications [3] adopted by the ASME.
However, once the specication is adopted, the prex changes from the letter A to the letters SFA. The sufx M indicates that the latest revision includes metric equivalents. As AWS specications are issued or revised the metric units are now included. Additionally, the ISO designations are being listed in the electrode or ller metal classications within the specication. Usually, this is for comparison purposes only. However, SFA The dual classication extends to the marking and label that is afxed to the electrode package.
Included are material descriptions, welding material applications, welding material procurement, the ller metal certication system, and the electrode classication system. metals, and uxes for the developing U. pressure vessel industry, asme section ii part b pdf free download. Inthis joint activity was dissolved and the AWS assumed sole responsibility for welding-related materials.
Section II, Part C was developed by the ASME to include the Welding Material Specications published by the AWS and adopted by the ASME for Code fabrication. In the edition of Section IX, the ASTM Welding Material Specications were assigned F-numbers, but by the winter addenda to Section IX, these had been replaced with corresponding AWS Specications. The Guideline on the Approval of New Welding and Brazing Material Classications under the ASME Boiler and Pressure Vessel Code explains the process for adoption of new materials.
This guideline is located at the beginning of Section II, Part C and is similar to the guidelines for base metals in Sections II, Parts A and B. The AWS Specications are developed and written by voluntary industrial experts, much as the rules developed for pressure vessel manufacturing in the ASME Code.
Technical inquiries to Section II, Part C are also handled by the Subcommittee on Welding Section IX. Generally, inquiries to Section II, Part C are referred to the appropriate experts on the AWS committees on welding ller metal for resolution. Section IIC contains only those specications that are relevant to ASME Code fabrication. Included within these specications are classications of welding rods, electrodes, and ller metals.
Because all welding material classications are contained in the specication, some materials may not be applicable for ASME Code fabrication. P-numbers are groupings of base metals in Section IX that reduce the required number of welding and brazing procedure qualications. The AWS was formed in when the National Welding Council was discontinued. Inthe AWS and the ASTM both formed the joint AWS ASTM Committee on Filler Metal to provide standard specications for welding rods, electrodes, ller.
Additional materials included in these specications are gas tungsten arc welding GTAW electrodes, welding uxes, brazing ller metal, brazing uxes, and shielding gases.
Classication is based on a combination of chemical composition, strength, usability, toughness, chemical composition, hydrogen content, and any special characteristics.
Specication, SFA Recently, SFA Two important features of Section II, Part C, asme section ii part b pdf free download, aside from the Welding Material Specications, are SFA As stated previously, SFA The Appendices to the SFA specications are excellent guides that describe the individual electrodes, properties, and uses. If questions arise concerning the use or testing of a particular welding electrode or ller metal, the appendices are good starting points for nding answers.
As the Ans. specications are revised Appendix A in each specication now contains a comparison of the Ans. classication with the ISO classication. Most electrodes have classications that include usability characteristics and chemical composition requirements. Section IX Welding and Brazing Qualications further denes these characteristics and requirements in paragraphs QW and QW for welding qualication.
The usability characteristic of an electrode determines the F-number assigned in Table QW of Section IX. F-numbers are referenced by the essential, supplemental essential, and nonessential welding variables in Section IX for welding procedures and performance qualication. The chemical composition of the undiluted weld deposit determines the A-number assigned in Table QW asme section ii part b pdf free download Section IX. A-numbers are referenced in the welding variables of Section IX for welding asme section ii part b pdf free download qualication requirements involving ferrous metals.
F-numbers and A-numbers for welding and brazing materials are highlighted throughout this chapter for many of the commonly used electrode classications. Each of the individual Welding Material Specications contain acceptance and certication statements. The following are the statements from SFA For certication: By afxing the AWS Specication and Classication designations to the packaging, or the classication to the product, the manufacturer certies that the product meets the requirements of this specication.
Both acceptance and certication of welding materials are very important to ASME Code users. Depending on the fabrication section of the Code, the User should understand these basic requirements so that welding material is procured correctly. The fact that a Welding Material Manufacturer places the AWS Specication and classication on the container does not mean that the tests required by the specication are conducted on that particular lot of welding materials.
It means only that the Manufacturer conducted the required testing on material representative of that welding material. Further discussion on acceptance and certication is covered in the discussion on SFA The following are summaries of the contents of the individual Welding Material Specications.
The purpose of these discussions is to explain the Welding Material Specications and relate them to ASME requirements. When possible, references are made to ASME base metal specications that can be welded with a specic classication asme section ii part b pdf free download electrode, rod, or ller metal.
Such references are intended as examples only rather than a complete listing of all the base metals for which each welding material is suitable. The guidelines provide detailed methods by which the individual ller metals are lot classied and tested. When procuring materials for ASME Code fabrication, regardless of whether a Certicate of Conformance or a Certied Material Test Report is required, these guidelines should be followed. As each specication states, the acceptance of the welding material is in accordance with the provisions of SFA The guidelines begin with denitions that describe various aspects or characteristics of welding materials, such as heats, asme section ii part b pdf free download, lots, batches, blends, and mixes, asme section ii part b pdf free download.
These denitions are followed by specic lot classications based on the type of welding material being procured. Four lot classications describe the size of a production run of welding materials: covered electrodes, bare wire, ux-cored electrodes, and ux.
These classications allow the purchaser to specify the level of control and the lot size necessary to meet the application. If the welding material is for Section III, Division 1, Class 1 nuclear component fabrication [7], the lot classication selected should meet the requirements of Section III, Subsection NB, paragraph NB If the application does not require lot controls, these classications are less important.
Testing levels begin with Schedule F, which is the Manufacturers standard. If welding materials are procured without specied requirements i. The welding material would be supplied with the required markings on the container to serve as certication that the welding material meets the specication requirements.
However, the markings certify only that material representative of that being delivered was tested at some time in accordance with the Material Manufacturers standard practice.
A typical certication would be provided upon request. If the purchaser wants a Certied Material Test Report for the tests required for the classication of each lot shipped, Schedule J asme section ii part b pdf free download be specied, which requires that the Welding Material Manufacturer perform all the classication testing required by the specication on the lot of material ordered. A Certied Material Test Report would then represent the actual lot or lots of welding material being delivered.
Schedule K, a level of testing specied by the purchaser, can be selected when ller metal to Section III NB requirements is ordered. For Section III welding materials, the level of testing is based on the design of the component, the welding procedure and postweld heat treatment that will be used in fabrication.
Therefore, the purchaser might list the tests and acceptance criteria, including certication requirements, in the purchase order. The nal guideline is one that illustrates and gives examples of methods for use when welding materials are procured. One should remember the importance of ordering the correct welding material to meet specic Code requirements.
The purchasers acceptance of the wire can be satised only if the correct lot clas. sication and level of testing are included in the order, in addition to the quantity, size, and type of ller metal or electrodes. Details regarding sizes and packaging that previously resided in the ller metal specications were placed in A 5. It takes into account the requirements of a similar specication, ISOand allows classication in both U.
Customary units and Metric SI units. As ller metal specications are revised, sizes and packaging sections will be removed and A 5. Covered electrodes are classied in SFA Figure 3. The letter E at the beginning of the classication stands for asme section ii part b pdf free download the rst two numbers that follow either a 60 or 70 designate the minimum required tensile strength in ksi 1, psiand the third number designates welding position usability.
For example, the 1 in E indicates that the electrode is usable in all positions at, horizontal, vertical, and overhead. The third number is then taken together with the fourth number i. Sometimes, optional supplemental designators are used to further identify electrodes that meet certain addition requirements. The 1 designator in E means that the electrode meets impact requirements at a lower temperature than that required for the classication.
Low-hydrogen electrodes can also be given the optional designator R, such as in ER, to indicate that the electrodes meet low-moisture-absorption i. Even more optional supplemental designators can be included for moisture or hydrogen testing. Therefore, an EH4 electrode produces a minimum 70 ksi tensile strength weld deposit 70has a low-hydrogen coating for alternating current ac or.
Covered electrodes are composed of a covering and a carbon steel core wire. Flux, minimal alloying, and iron powder in some classications are used to make the covering. The core wire is usually carbon steel that has a chemical composition different from that of the weld deposit. Low-hydrogen electrodes E, E, E, EM, E, and E have low-moisture i.
The E60XX electrodes have cellulose, titania, or similar coverings that are not low in hydrogen.
