Advanced Documentation & Materials Traceability Records
You get the experience of our project managers and certified welders to ensure every detail of your project is engineered, fabricated, documented and inspected to regulation. From in-house inspections, 3rd party inspections to the 7 CWIs on staff, we know what requirements your parts need.
Our advanced inventory tracking also ensures your materials are compliant. Anderson Dahlen does not purchase any raw materials without complete material markings including Original MTRs in a digitally format and in an atmospheric controlled environment. Heat numbers for all component parts are tracked throughout the fabrication process.

Thank you to you and your team who assisted me during my visit. Both the customer and I were hugely impressed with everything from start to finish. The actual FATs were one of the smoothest that I have experienced in 20 years. I look forward to working with you in the future. Martin Kelly, Thermo Fisher

Thank you to Gary and the fabricators who helped us remove the scratch and refinishing our aluminum part. You saved us a ton of time and kept us on track for an on time delivery to our customer. We definitely owe you one! Clint Bitterman, VP-Co Owner of Master Tool & Mfg Inc.
Their willingness to spin a large part well off axis made it possible. Their attention to detail made it a success. Equally praiseworthy is their communication during the manufacturing process, assuring the best part.
