Indicate if reheat maintenance is during welding or until pOStWeid near treatment is pegrrned 2. Active view current version of standard. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Combining values from the two systems may result in nonconformance with this practice. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. A Indicate minimum root radius and minimum side wall angle.
Standard Practice for Steel Castings, Welding, Qualifications of Procedures and Personnel
Last previous edition A A M The dimensions of the welding groove are not essential variables of the welding pro cedure. Guided bend test specimens are of three types depending on which surface awtm, face, or root is on the convex outer side of the bent specimen.
Root Bend 2 Range of Thickness Qualified: Root Bend 1 Results Laboratory Test No. If the castings are not to be postweld heat treated, then the test material is not to be postweld heat treated. DThe ends may be threaded or shaped to fit the holders of the testing machine in such a way that the load is applied axially.
Single or Multiple Pass: Charpy Impact Test 9.
Welding shall be done without rotating the pipe or casting so that the weld metal is deposited from the? The welder or operator successfully astmm the procedure qualification test is automatically qualified for performance.
C The maximum thickness quali? Heat-affected zone coupons for impact specimens shall be taken transverse to the weld and etched to de?
Originally published as A 63 T. Metric Equivalents Y 8 [mml t, in. Where the material thickness permits, the axis of a heat-affected zone specimen may be inclined to allow the root of the notch to align parallel to the fusion line Fig. a48

The other two surfaces shall be called the face and root surfaces, the face surface having the greater width of weld. Post-Weld Heat Treatment A Where applicable, indicate electrode care instructions. A Indicate the heating and cooking rates, holding temperatures and times.
Changes other than those listed may be made without requalification, provided the procedure is revised to show these changes. The notch shall be cut normal to the material surface in the heat-affected zone to include as much heat-affected zone as possible in the resulting fracture Fig.
In lieu of an A number designation, the nominal chemical composition of the weld deposit shall be indicated on the Welding Material Aastm Fig.
Preparation of Awtm Material 6. If a recessed ring is used, this surface of the specimen may be machined to a depth not exceeding the depth of the recess to remove the ring, except that in such cases the thickness of the? Tensile strength equal to or greater than 85 ksi [ MPa].
Backing Strip, if any: Test material shall be oriented as shown in Fig. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Charpy Impact Test 9. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.
Qualification under any F number up to and including F4 shall qual a welder for all lower F numbers. It is the responsibility o the user o this standard to establish approf f priate safety and health practices and determine the applicability o regulatory limitations prior to use.
