The orientation of the welds with respect to the horizontal and vertical planes of reference is classified into four positions, namely, flat, horizontal, vertical, and overhead. 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. Qualification in the horizontal fixed position, or in a88 horizontal and vertical and overhead positions, shall qual for all positions Fig.

Standard Practice for Steel Castings, Welding, Qualifications of Procedures and Personnel
Qualification with A No. 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. Combining values from the two systems may result in nonconformance with the standard.
Was Backing Strip Used? The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Alternatively, the entire weld shall be removed and replaced by a quali?
This practice covers the qualification of procedures, welders, and operators for the fabrication and repair of steel castings by electric arc welding. If he fails these tests, he must undergo further training before a retest is permitted.
Work Item s – proposed revisions of this standard. In lieu of an A number designation, the nominal chemical composition of the weld deposit shall be 11 indicated on the Welding Material Speci? 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. Within the text, the SI units are shown in brackets.

Each specimen shall be tested and meet the requirements of 7. Also indicate whether preheat is requimd dwing metal mal. The welder or operator successfully performing the procedure qualification test is automatically qualified for performance.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 4a88
Surfaces of backing plates when used shall also meet the same cleanliness requirements. This abstract is a brief summary of the referenced standard.
Who by virtue of these tests meets the welder performance qualification. Guided bend test specimens are of three types depending on which surface side, face, or root is on the convex outer side of the bent specimen.
Electrical Characteristics A 9. Title welding of A steel castings. When using the wrap-around jig Fig. All thicknesses of pipe or cylindrical castings having an outside diameter greater than 3 in. C The maximum thickness quali? Low-alloy steel annealed, normalized, or normalized and tempered Tensile strength less than 85 ksi [ MPa].
The welding procedure shall conform to that given in the procedure qualification. A Indicate the single gas or proportional parts of mixed gases and?
C Indicate if preheat maintenance is during welding or until postweld heat treatment is performed. The centers of the specimens adjacent to the metal surfaces shall not exceed in. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Also indicate whether preheat is required during metal removal. A aetm epsilon e indicates an editorial change since the last revision or reapproval. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Test material shall be subjected to the same heat treatment before and after welding as will be applied to the casting.
