R-Design Suite
In process of accreditation.

Brief explanation: Micro- and macrostructure

Purpose:
To examine the weld quality by observing the internal structure of the weld and surrounding areas, identifying defects and assessing metallurgical features.

Standards Overview:

  • ISO 17639:
    Provides guidelines for visual examination of macro- and microsections of welds, including sample preparation, etching, and evaluation of weld profiles, grain structure, and possible defects.
In process of accreditation.

Brief explanation: Vickers method

Purpose:
To measure the hardness of metals and welded joints by applying a diamond indenter and evaluating the resistance to indentation.

Standards Overview:

  • ISO 6507-1:
    Defines the general Vickers hardness test method, including test force, indentation measurement, and calculation of hardness values.
  • ISO 9015-1:
    Applies the Vickers method to welded joints, specifying test locations across the weld, HAZ, and base metal for hardness profiling.
In process of accreditation.

Brief explanation: Fracture testing

Purpose:
To evaluate the quality of welded joints by detecting internal or surface defects after the specimen is fractured.

Standards Overview:

  • ISO 9017:
    Describes the method for fracture testing of welds, including specimen preparation, test procedure, and visual inspection of the fracture surface for flaws like lack of fusion, porosity, or cracks.
In process of accreditation.

Brief explanation: Bend testing

Purpose:
To assess the ductility and soundness of welded joints by checking for cracks or defects after bending.

Standards Overview:

  • ISO 5173:
    Specifies methods for bend testing of welds, including test types (face, root, side), specimen dimensions, bending angles, and acceptance criteria.
In process of accreditation.

Brief explanation: Impact testing

Purpose:
To measure a material’s toughness and its ability to absorb energy during sudden impact, especially at low temperatures.

Standards Overview:

  • ISO 148-1:
    General method for Charpy V-notch impact testing of metallic materials.
  • ISO 9016:
    Impact testing applied to welded joints, specifying specimen location and test procedures.
Active!

Brief explanation: Tensile testing

Purpose:
To determine the mechanical properties of materials and welded joints under tensile load, such as yield strength, ultimate tensile strength, and elongation.

Standards Overview:

  • ISO 6892-1:
    Tensile testing of metallic materials at room temperature.
  • ISO 4136:
    Tensile testing of welded joints using transverse specimens to assess weld strength.
  • ISO 15630-1:
    Tensile testing of steel reinforcement (rebars) for concrete structures.
