Electron Beam Welding

Electron Beam Welding provides great strength and consistent weld size of thick to thin materials. Many difficult to weld metals can be welded using the EB welding process. EB welding is able to achieve deep penetration while still having narrow welds.

Laser Welding & Cutting

Laser Welding and Cutting provides close tolerances, good edge quality and extremely fast feed rates. Laser welding provides minimal heat input; high welding speeds and welding in difficult access areas, with minimal or no finishing requirements.

Laser Welding >

Gas Tungsten Arc Welding

(GTAW) GAS TUNGSTEN ARC WELDING also known as TIG Welding provides high-quality welds because of the Argon Gas shielding of the molten weld pool. This process allows for strong high quality welds in Aluminum Stainless Steel and Magnesium.

GTA Welding >


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.

We have been serving the aerospace industry, continuously for over forty years. Other industries we serve are: Electronics, Energy, Industrial, Medical, Defense, Nuclear, Research, and Space. Our wide array of processes can provide you with one stop shopping for your metals joining and laser processing needs. Our specialty is in the area of Electron and Laser Beam Welding.
