Visual Welding Inspection commonly referred as (VT) is a fundamental inspection method used to assess the quality and condition of welded components throughout fabrication and construction projects. Performed at various stages before, during, and after welding, visual inspection plays a key role in identifying surface imperfections, confirming proper welding practices, and ensuring compliance with applicable codes, standards, and project requirements.
We provide professional Visual Welding Inspection services for structural steel, construction, fabrication, manufacturing, and a wide range of industrial applications, helping ensure quality workmanship, code compliance, and structural reliability throughout all stages of fabrication and welding.Our inspections are focused on supporting quality control, improving reliability, and helping clients address potential welding concerns before they lead to costly repairs or operational issues.
As part of the inspection process, our qualified inspectors examine welds for visible discontinuities and defects such as cracking, porosity, undercutting, excessive spatter, incomplete fusion, poor weld contour, and alignment issues. We also review weld sizing, joint configuration, fit-up, root spacing, and general workmanship to verify conformance with approved welding procedures, engineering specifications, and applicable industry standards.
Visual inspection is performed at key stages of the welding process: before welding, during welding, and after completion. Pre-weld checks verify material condition, joint preparation, alignment, and consumables. During welding, we monitor technique, heat control, and workmanship. Final inspection confirms weld appearance, dimensional accuracy, and compliance with requirements.
Inspections are carried out in accordance with structural welding standards such as CSA W59 and AWS D1.1, using calibrated tools including weld gauges, measuring devices, mirrors, borescopes, and proper lighting to ensure accurate assessment and reporting.
Visual inspection is a cost-effective quality control method that helps identify defects early, reducing the risk of structural issues, delays, and costly repairs.
We support structural steel fabrication and construction projects, providing detailed reports with observations, measurements, and any non-conformances, along with corrective action recommendations when required.
Our inspectors work closely with fabricators, contractors, and engineers to ensure safe, compliant, and high-quality welding work in both shop and field environments.
Visual welding inspection is a quality control process where welds are examined at different stages—before, during, and after welding—to ensure they meet required standards and specifications.
It is generally performed at three stages: pre-weld (material and joint checks), in-process (monitoring welding activity), and post-weld (final weld evaluation).
We perform inspections in accordance with contract documents, drawings, applicable structural welding codes and standards such as CSA W59 and AWS D1.1, as well as project-specific requirements.
