Founded in 1971 by Robert and Jean DeSilvestri. The Pasadena, California location is headquartered in a modern 20,000 square foot facility. The company has established a nationwide and growing international reputation for excellence in metals joining, metallurgy, design, fabrication, machining and assembly. ATCo is a qualified "woman-owned" small business with excellent financial stability.
ATCo is among the few facilities offering Nadcap accredited electron beam welding; laser cutting, drilling and welding; automatic and manual gas tungsten arc (GTA) welding. Because of this diversity in equipment and services, a customer is afforded the most cost-effective process.
WHY CHOOSE ATCo
ATCo’s success is based on a simple common philosophy that is geared to timely processing of customer products with the highest quality. The company is sized to achieve reasonable economies of scale, yet small enough to be responsive and have efficient customer contact.
ATCo is unique in accelerating the pre-fabrication cycle. ATCo’s hands-on engineering group can quickly develop a sound fixture/tooling concept, solidify the design and have the hardware processed in-house in a short time. Equally talented are the weld/metallurgical engineers who can direct the process technicians through an efficient weld parameter development.
