Structural Steel Inspection in Alberta, Canada

Structural steel NDT (Non-Destructive Testing) and visual inspection are techniques used to evaluate the condition, integrity, and safety of structural steel components used in buildings, bridges, towers, and other steel structures. These inspections aim to detect defects, corrosion, weld discontinuities, or any abnormalities that could compromise the structural integrity of the steel elements.

Structural steel inspections typically involve a combination of NDT methods and visual inspection techniques, which may include:

1. Magnetic Particle Testing (MPT): MPT is used to identify surface or near-surface defects such as cracks, lack of fusion, or weld discontinuities. It involves applying magnetic particles to the steel surface, which are attracted to and reveal any magnetic flux leakage caused by defects.

2. Ultrasonic Testing (UT): UT is employed to assess the thickness and integrity of structural steel components. It uses high-frequency sound waves to detect internal flaws, such as corrosion, laminations, or weld defects, by analyzing the reflected sound waves.

3. Visual Inspection: Visual inspection is a fundamental component of structural steel assessments. It involves a thorough visual examination of steel members, connections, welds, coatings, and associated components. Inspectors look for signs of corrosion, surface irregularities, misalignments, weld quality, or any visual indications of structural issues.
