Welding Inspection & Certification

Fabricated welded joints undergo a variety of quality assurance tests to ensure their integrity and performance. These tests range from basic visual scanning and inspection to more advanced non-destructive testing (NDT) methods. In some cases, mechanical tests, such as hardness testing, and corrosion resistance assessments, like surface contamination tests, are also conducted to verify the durability and reliability of the welds.

Visual inspection is the initial and most straightforward method used to assess welded joints. This process involves carefully examining the welds to identify any surface defects, such as cracks, porosity, or improper weld bead formation. It provides a quick way to detect visible flaws that could compromise the strength or appearance of the weld.

Non-destructive testing (NDT) methods are employed to evaluate the internal structure and integrity of the welds without damaging the material. Techniques such as ultrasonic testing, radiographic examination, magnetic particle testing, and dye penetrant inspection are commonly used to detect hidden defects, such as internal cracks, voids, or inclusions. These tests provide critical information about the weld quality without the need to cut or destroy the welded components.

Occasionally, mechanical tests like hardness testing are performed on welded joints to determine their resistance to deformation and wear. This test helps assess the strength and durability of the weld, ensuring that it meets the required specifications for its intended application.

In addition to mechanical tests, corrosion resistance tests are sometimes conducted to evaluate the weld’s ability to withstand environmental factors. One such test is the surface contamination test, which checks for the presence of contaminants that could lead to corrosion. Ensuring that welded joints are free from such contaminants is essential for their longevity and performance, especially in harsh environments.
