Certified welding is important because it gives the customer a high degree of trust that their welds are safe and sound. All certified welds are the result of work from multiple people. Namely, engineers, CWI’s, and welders. Certainly, they all hold each other accountable for their work. Firstly, it starts with the design of the welded joints that follow the American Weld Society (or customer-based specifications). Then, it ends with the final visual inspection of welds by a trained professional. Alas, Certified welding is never the work of an individual, but rather a team of experts!

Certified Welding Inspector
Our in-house Inspector ensures the highest level of quality workmanship by providing direction for making sound and superior production welds. A CWI is certified through AWS . AWS is an independent, non-profit organization that creates welding standards in accordance with codes. Of course, certification requires the use of only certified materials, including consumables, with the guidance of a WPS.
A Welding Procedure Specification (WPS) is a document that guides welders to the accepted procedure that is reliable and repeatable. Surely, they are used to outline shop and field welding, per the code requirements. Indeed, code requirements are illustrated on the Welding Procedure Data Sheet (WPDS). Therefore, this details the welding parameters, ranges and limitations for a welding process. Finally, each welding procedure specification includes essential variables to maintain the qualifications to meet the specifications of your welding projects.
Features that certified welds have that other welds do not:
- Certified joint designs have decades of research behind them to verify that they will survive the stresses that they will encounter for their entire life.
- A WPS controls the variables of a certified weld. For instance, a specification ranging from allowable weld positions to filler material used to weld deposition type.
- Each person involved has had formal training and has records available.
Many of our customers require certified welding, such as MnDOT. However, some of our clients do not require certified welding. Nevertheless, we still have a policy in place, and welders trained and tested to AWS standards, regardless. This is truly indicative of our company’s ability and commitment to quality. In other words, we know bringing our work to a higher, tested degree of quality gives our customers’ confidence. In addition, weexcel in challenging set ups and can do custom one off high mi low volume arena
