Attributes of a welding inspector


To perform duties in the most effective manner, the welding inspector should be in good physical condition. Since the primary job involves visual inspection, it is obvious that the welding inspector should have good vision, whether natural or corrected. For instance, if colour or contrast is important to the inspection process being employed (liquid penetrant, magnetic particle, or colour coded parts) then an individual should be tested for the ability to detect those colours. The AWS Certified Welding Inspector (CWI) program requires a minimum 20/40 visual acuity and the ability to perceive certain colours, as determined through actual testing. Another aspect of physical conditioning involves the size of some welded structures. Since welds could be located anywhere on a very large structure, the inspector must be capable of going to the weld at any location in order to make an evaluation. The inspector must comply with safety regulations when performing these duties. The ability of the welding inspector to get to the work may be reduced if the inspection is not performed immediately after welding. For example, such aids for the welder. As ladders and scaffolding may be removed, making access impossible or dangerous. Within safety guidelines, the welding inspector should not be prevented from performing a proper inspection because of a physical condition. While there may be no specific level of education and training required for welding inspectors, the job may involve interpretation of results. Therefore, an individual must have at least some level of technical knowledge to perform well as an inspector. In order to perform welding inspection, the individual will continually be asked to make judgments based on visual observations of physical characteristics of welds and weldments and their comparison with drawings or standards. If an individual is unable to understand some written requirement, it will be difficult to make a judgment as to a weld’s acceptability in accordance with that standard. There is more to evaluation than just reading the specifications. Once read, the inspector must interpret its meaning. Even then, some requirement of code or specification may appear very clear and straightforward when initially read; however, comparison of this written requirement with an existing physical the condition may still prove to be extremely difficult. Technical ability is also necessary in order for the welding inspector to effectively express ideas or inspection findings. In addition, once an inspection has been performed, the inspector must be capable of describing the methods used and subsequent results with sufficient accuracy to adequately communicate to others familiar with the work being performed.
