Standard Practice for Steel Castings, Welding, Qualifications of Procedures and Personnel
A Indicate heat treatment before welding. Active view current version of standard Translated Standard: 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. Welding Details times The centers of the specimens adjacent to the metal surfaces shall not exceed 5? Root Bend 1 Active view current version of standard. If he fails these tests, he must undergo further training before a retest is permitted.
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. This practice covers the qualification of procedures, welders, and operators for the fabrication and repair of 4a88 castings by electric arc welding.
Carbonmanganese steel tensile strength equal to or greater than 70 ksi but less than 90 ksi [ MPa]. Root Bend 2 A Indicate minimum distance for local preheating. Indialte amenskn ofmaximum gap. B Indicate maximum temperature. If direct, state whether non-pulsed or pulsed.
Guided Bend Test 8. Electrical Characteristics A 9. W488 suggested form for recording such information is shown in Fig. The welding procedure shall conform to that given in the procedure qualification. All thicknesses of pipe or cylindrical castings having an outside diameter greater than 3 in.

Thickness, t, of Test Plate or Pipe as Welded, in. Tensile strength equal to or greater than 85 ksi [ MPa].
ICS Number Code Test plate material for performance qualification xstm is covered in Carbonmanganese steel tensile strength equal to or greater than 70 ksi but less than 90 ksi [ MPa]. A suggested form Fig.
The weld to be radiographed shall be at least 6 in. C Where only a single coupon is required, the center of the specimen should be midway between the surfaces.
Backing Strip, if any: Heat-affected zone coupons for impact specimens shall be taken transverse to the weld and etched to de? Each specimen shall be oriented so that the notch is normal to the surface of the material and one face of the specimen shall be within 1?
Test material shall be oriented as shown in Fig. All welders and operators welding castings under this practice shall pass the welder qualification test. The cut surfaces shall be designated the sides of the specimen.
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. 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.
Heat-affected zone coupons for impact specimens shall be taken transverse to the weld and etched to define the heat-affected zone. If he fails these tests, he must undergo further training before a retest is permitted.
