Our Services
Welding inspection is a critical process ensuring the integrity, safety, and quality of welded structures and components. It involves a series of evaluations performed on-site and in controlled environments to verify compliance with applicable codes, standards, and specifications.
On-Site Inspections
On-site welding inspections are conducted at the fabrication or construction location to monitor welding operations in real-time. Inspectors verify that proper procedures, materials, and techniques are being employed. They check for adherence to welding procedure specifications (WPS), preheat and interpass temperatures, and post-weld heat treatment processes. On-site inspections help detect issues early, preventing costly rework and ensuring welds meet quality requirements.
Visual Testing (VT)
Visual Testing is the most fundamental and widely used non-destructive testing (NDT) method in welding inspection. It involves a detailed visual examination of welds to identify surface discontinuities such as cracks, porosity, undercut, incomplete fusion, and other imperfections. This method requires skilled inspectors who are trained to recognize weld defects and interpret their severity according to relevant standards.
Dye Penetrant Testing (PT)
Dye Penetrant Testing is a reliable NDT technique used to detect surface-breaking defects in welds and base materials. The process involves applying a liquid dye to the weld surface, allowing it to seep into any cracks or pores. After a set dwell time, the excess dye is removed, and a developer is applied to draw out the penetrant from defects, making them visible under appropriate lighting. PT is especially effective for detecting fine cracks and other discontinuities invisible to the naked eye.
American Welding Society- Certified Welding Inspectors (AWS CWI)
Welding inspections are often performed by Certified Welding Inspectors accredited by the American Welding Society (AWS). AWS CWIs have demonstrated extensive knowledge and experience in welding processes, codes, and inspection techniques. Their certification assures clients that weld inspections are conducted with the highest level of professionalism, accuracy, and compliance to industry standards.
Together, these inspection methods and certified professionals ensure welded structures meet safety and performance requirements, minimizing the risk of weld failure and enhancing long-term reliability.
