A review of published and unpublished information on mechanical tests, procedure-qualification tests, fluorescent and dye-penetrant, radiographic and ultrasonic inspection, sectioning of welded structures, magnetic inspection, corrosion testing, metallographic tests, ferrite, carbide and sigma-phase determination and crack-sensitivity tests.
Testing procedures for stainless steel weldments can generally be divided into those in which (1) special welds are prepared (usually on plates or pipes) to serve as qualification tests for a particular welding procedure prior to its use or fabrication, ( 2 ) special weldments (also known as ?mockups?) are made under controlled conditions to evaluate electrode and base-metal materials, (3) a welded section is removed from fabricated equipment (as, for example, a section out of a main weld seam in a pressure vessel or pipe) and (4) completed welds are evaluated without requiring the partial destruction of the fabricated weldment (i.e., nondestructive tests). Each particular testing procedure is determined either (a) because of the recommendations of accepted standard specifications and codes, or (b) because experience has shown that this procedure will evaluate a particular property of the material or (c) because of the nature of the service environments to which the completed weldment will be exposed.
