Work Item s – proposed revisions of this standard. The welder or operator successfully qualified with one procedure for a process is qualified to weld with any other welding procedure using the same welding process, unless requalification is required by Section BoxMiami, FL The base material shall be attached B to the welding electrode lead.

Test material shall be subjected to the a48 heat treatment before and after welding as will be applied to the casting. A bend bar comprised of parent metal heat treated to the ductility and strength requirements of the applicable specification shall be bent to failure. A superscript epsilon E indicates an editorial change since the last revision or reapproval. The astmm to be radiographed shall be at least 6 in.

It is informational only and not an official part of the standard; the full text of the standard aastm must be referred to for its use and application. Link z488 Active This link will always route to the current Active version of the standard. A suggested form Fig. Qualification under any F number up to and including F4 shall qual a welder for all lower F numbers. All welders and operators welding castings under this practice shall pass the welder qualification test.


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. Indicate if reheat ashm is during welding or until pOStWeid near treatment is pegrrned 2. 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 Indicate minimum distance for local preheating. Groove dimensions as shown in Fig. Originally approved in It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. The welding procedure shall be in accordance with that given in the procedure quali?

E Weld should be in center of reduced section. The materials are categorized as carbon steel, carbon and carbon-manganese steel, low alloy steel, ferritic stainless steel, martensitic stainless steel, low carbon austenitic stainless steel, unstabilized austenitic stainless steel, austenitic stainless steel, duplex austenitic-ferritic stainless steel, precipitation-hardened austenitic stainless steel, nickel base alloy, steel castings, austenitic manganese.

Standard Practice for Steel Castings, Welding, Qualifications of Procedures and Personnel

Carbonmanganese steel tensile strength equal to or greater than 70 ksi but less than 90 ksi [ MPa]. Each specimen shall be tested and meet atm requirements of 7.


Guided Bend Test 8. Four types of test shall be conducted in the qualification procedures such as tension test, bend test, Charpy impact test and radiographic test. This standard does not purport to address all of the safety concerns, if any, associated with its use.

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.

The presence or absence of up to 0. Preparation of Base Material. Combining values from the two systems may result in nonconformance with this practice. 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?

Combining values from the two systems may result in nonconformance with the standard. 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.
