In close cooperation with others, Q4S can provide non-destructive testing (NDT) for a diverse range of industries.


We help you to ensure the reliability and safety of your products, equipment or plant assets with our services in non-destructive testing, materials testing and welding quality. Q4S understands the processes involved throughout the entire product cycle – from design and manufacture to operation and maintenance - and the frequent need for rapid turnaround times. Our services can support production processes, quality control, and regulatory compliance as well as new construction, pipelines, plant maintenance and scheduled shutdown inspection.


Our vast expertise and knowledge in NDT and materials testing means we can select the right techniques and procedures to detect defects and irregularities in your products, equipment, production facilities or plant assets and provide you with necessary data to assist you in making informed decisions.  Q4S can help you avoid the potential for catastrophic consequences and financial losses with early detection of problems before they cause damage, operating inefficiencies or in-service failure.


In addition to non-destructive testing services, we provide a complete welding support service to help you to comply with regional and international codes and standards
