Destructive Testing Laboratory for Welds

Our laboratory handles various destructive tests to ensure the quality, durability, and safety of welds. These tests are essential for maintaining high standards in welding practices, ensuring the safety and reliability of welded structures and components. Here are the main aspects and functions of our laboratory.

These tests are essential to ensure that welds meet quality and safety standards, thereby ensuring the reliability and longevity of welded structures.

Tensile Tests

  • Objective: Measure the strength of the weld.
  • Procedure: Apply tension until the weld sample breaks.
  • Expected Results: Maximum force supported by the weld before breaking.

Bending Tests

  • Objective: Assess the ductility and strength of the weld.
  • Procedure: Bend the weld at a specified angle.
  • Expected Results: Weld behavior under bending, absence of cracks or defects.

Impact Tests

  • Objective: Evaluate the toughness of the weld material.
  • Procedure: Subject the sample to sudden impacts.
  • Expected Results: Weld's ability to absorb impact energy without breaking.

Hardness Tests

  • Objective: Determine the hardness of the weld and heat-affected zones.
  • Procedure: Use different methods such as Vickers, Rockwell, or Brinell to measure hardness.
  • Expected Results: Hardness values indicating resistance to indentation.

Macro and Micrographic Examination

  • Objective: Inspect the internal structure of the weld.
  • Procedure: Cut and polish a weld sample, followed by visual inspection at different magnifications.
  • Expected Results: Identification of internal defects such as cracks, porosities, or inclusions.

Chemical Composition Analysis

  • Objective: Determine the chemical composition of weld materials.
  • Procedure: Use techniques like spectrometry to analyze the chemical elements present.
  • Expected Results: Compliance of the chemical composition with required specifications.

Metallographic Analysis

  • Objective: Examine the microstructure of the weld.
  • Procedure: Study the microstructure using metallographic microscopes.
  • Expected Results: Identification of potential problems in the material structure.

Test Reports

  • Objective: Provide detailed reports of test procedures and results.
  • Content: Description of methods used, test results, analyses, and conclusions on weld quality.
