Non-Destructive Testing: Visual Testing Services
Welding is a step by step process, and as such, the first line of non-destructive testing (NDT) is visual testing before, during and after the welding process is complete. D-Arrow Inspections employs CWI (certified welding inspectors) that have years of experience in overseeing welding operations to ensure maximum quality throughout the job.
A weld must be acceptable to visual testing as part of code guidelines, and visual weld inspection can determine if a weld is bad before the need to employ more sophisticated welding inspection methods.
The first step in visual testing is to ascertain that the area to be welded is acceptable. This means that the area is adequately clean and free of contaminants like grease, dirt and other things that can cause a disruption to the welding process and imperfections in the weld itself.
As the welding begins the CWI looks for inclusions, checks the evenness of the weld bead and crater level as these things if not done properly can lead to cracking and other issues that can cause a weld to fail or be sub-standard.
Finally, visual testing includes examination of the finished weld to ensure quality within certain parameters and if the weld is acceptable.
The CWI at D-Arrow Inspections have a trained eye and hold exacting standards in what they consider to be an acceptable and quality weld. This commitment to attention to detail will help to ensure that your company continues to be known for its quality long after the order is filled.
