CHICAGO—A company that’s been making news recently with its Electron Beam Additive Manufacturing (EBAM®) process made its mark in the welding industry.

Sciaky, Inc., which reported in June that its EBAM process achieved the fastest deposition rate for industrial metal 3D printing, is a long established innovator of electron beam welding (EBW) and advanced arc welding systems. The company also provides contract electron beam and arc welding services to customers in a wide range of industries, from aerospace and defense to automotive and healthcare.

“Our welding equipment meets rigid military specifications to manufacture items such as airframes, landing gear, jet engines, guided missiles, and vehicle parts,” the company said in a release.

Sciaky’s job shop EB welding capabilities include welding of large assemblies up to 24 feet in length or 92 inches in diameter, as well as tiny parts that fit in the palm of one’s hand, the company said in a brochure detailing its services. The company said EB welding “is an excellent choice for applications containing refractory alloys and dissimilar materials.”

Advantages of the process are reported to include a high power density with very low overall heat input, resulting in minimum distortion. “Electron beam welded parts require a minimum of post-weld machining and heat treatment, and, unlike other fusion welding processes, electron beam requires no shielding gases. The weld quality is exceptional, while the process is fully automated and extremely efficient—typically 90 percent,” the company said.

Sciaky said it operates a process development laboratory, staffed with  highly qualified personnel and the latest equipment, to evaluate customers’ specialized welding applications and feasibility programs.

“Our skilled technicians offer the latest welding processes, system design, weld joint design, metallurgical expertise, and programming skills,” the company said on its website. “The process laboratory occupies about 4,000 square feet within the service facility. Additional testing, such as radiographic inspection and ultrasonic inspection, is available as well.”
