All thicknesses of pipe or cylindrical castings having an outside diameter greater than 3 in. Originally published as A4488 63 T. Guided bend test specimens shall be prepared by cutting the test plate or pipe to form specimens of approximately rectangular cross section. Collectively, all of the specimens required to represent the full thickness of the weld at one location shall comprise a set.
asym If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
B Indicate whether atm positive EP or electrode negative EN output terminal of power supply is used. 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. Test material shall be oriented as shown in Fig. If multiple specimens are used, one complete set shall be made for each required test. The side-bend specimen shall then be capable of being bent to within 5″ of the angle thus determined.
The welding procedure shall conform to that given in the procedure qualification. Test material shall be subjected to the same heat treatment before and after welding as will be applied to the casting. Thickness, t, of Test Plate or Pipe as Welded, in.

Current edition approved Mar. Electrical Characteristics A 9. The ast, stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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. Separate welding procedures are required for each category. Current edition approved May 1, P-number designations in the ASME grouping of base metals for qualification may be different than the zstm numbers listed in Table 1.
A number in parentheses indicates the year of last reapproval. Indicate if reheat maintenance is during welding or until pOStWeid near treatment is pegrrned 2.
Backing Strip, if any: If the castings are not to be postweld heattreated, then the test material is not to be postweld heat-treated.
In the event the production weld requires welder or operator quali? The side of the specimen turned toward the gap of the jig shall be the face for face-bend specimens, the root for root-bend specimens, and the side with the greater number of defects, if any, for side-bend specimens. 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.
When postweld heat treatment consists of a full reheat treatment of the welded part, thus eliminating the HAZ, impact testing of the HAZ shall not be required. A Where applicable, indicate electrode care instructions. Preparation of Test Plate 5.

Standard Practice for Steel Castings, Welding, Qualifications of Procedures and Personnel
In the event the production weld requires welder or operator qualification, the entire production weld made by that welder or operator shall be radiographed and repaired by a qualified welder or operator. This standard is subject to revision at satm time by the responsible technical committee and must be reviewed every?
P-number designations in the ASME grouping of astn metals for quali? A Indicate general material description in the Title. P-number designations in the ASME grouping of base metals for qualification may be different than the category numbers listed in Table 1.
When using the wrap-around jig Fig. If he fails asgm tests, he must undergo further training before a retest is permitted. Guided bend test specimens are of three types depending on which surface -side bend, face bend, or root bend is on the convex outer side of the bent specimen.
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 finished specimen shall be that specified above. Welding Details times Qpes of Tests aztm.
If pulsed, state frequency.
