Welding joins pieces of metal by the use of heat, pressure or both. Welding is among the most dangerous industrial activities. It requires an enormous degree of precautionary planning because of the risk of personal injury. Gases and fumes can be significantly reduced with process controls and shielding gases.
What is a CWI?
Certified welding inspectors work in various industries related to construction. Furthermore, certified welding inspectors’ daily duties are filled with numerous responsibilities that are essential in maintaining the safety standards of in the construction industry. On the job site, certified welding inspectors ensure that all related construction activities follow specific guidelines, in accordance with city, state, and federal safety regulations. They also inspect plans, verify inspection and welding calibrations, and make sure that all welding materials are in proper condition for future projects. Additionally, welding inspectors inspect all welding equipment, such as regulators, cables, and welding machines.
During the construction phase, welding inspectors are responsible for monitoring heating values, ensuring the proper temperature controls are being used, and verifying that individuals maintain all compliance issues.
With the explosion of welding and metallurgical websites on the internet, why should anyone use a forensic welding engineer/expert? It is so easy to go online and find welding engineering data, equipment specifications, electrode parameters, welder blogs and perhaps even examples of weld failure assessments by others in many countries from years ago? Who would want to present these findings in court?
The internet is a great tool for legal research, especially if all you need to do is find a quick answer to a non-consequential welding question or a single failure incident that was classified as “failed weld”, or a list of questions to ask when cross-examining the opposition’s expert witness. However, seasoned attorneys prefer inputs from a proven welding engineer when organizing a complex court case that spanned multiple years and without precedence in any court.
During my life, I welded, supervised welders, engineered welds and inspected welds in many industries. Some welds were acceptable and some welds were rejected. It is important to note these terms, “accept and reject”. Every person (company and personal) involved in the welding operation needs to perform their assigned duties (design, materials, processes, and compliance). When there is a weakness in any one of these functions, the “welder” gets blamed for a bad weld.“Beauty is in the eye of the beholder”. This is also true for welds.
