Electron Beam Welding Services

Electron beam welding services use a narrow beam with high energy density to weld metals and alloys with a narrower heat effect zone and deeper penetration compared to most other welding processes. They often specialize in working with metallic elements such as aluminum or copper, or with alloys such as stainless steel, structural steel, and tool steel. Electron beam welding services that can join exotic metals or thermoplastic resins are also available. These companies are located across North America and around the world.

Electron beam welding services work with various types of metals. Aluminum is a silvery-white, ductile, metallic element with good conductive and thermal properties. It is used to form many hard, light, corrosion-resistant alloys. Copper is a ductile, malleable, reddish metallic element that is one of the best conductors of heat and electricity. Stainless steel is a family of corrosion-resistant steels that contain a minimum of 10% chromium. Nickel, molybdenum, titanium, niobium and other elements may also be present. Structural steels are large, part-strength steels used to build structural components.  Electron beam welding services that can work with tool steel are also available.

Electron beam welding services meet various certification and quality requirements. AS-9100 is a Society of Automotive Engineers (SAE) standard for aerospace manufacturers. QS-9000 is a quality standard for suppliers of DaimlerChrysler Corporation, Ford Motor Company, and General Motors Corporation. Both AS-9100 and QS-9000 are based on the 1994 edition of ISO 9001, but contain additional industry-specific requirements. ISO 14001 specifies requirements for environmental management systems. ISO 9001:2000 establishes requirements for a company's quality management systems. ISO/TS 16949:2002, an automotive standard for electron beam welding services that supersedes QS-9000, includes the process approach from ISO 9001:2000.

Some electron beam welding services are authorized by the American Society of Mechanical Engineers (ASME) to U-stamp code-constructed, unfired pressure vessels. Others are authorized to repair and alter unfired pressure vessels and to register those vessels with the National Board of Pressure Vessel Inspectors (NBPVI). Department of Transportation (DOT) registration is an important certification for electron beam welding services that fabricate and repair mobile tanks and vessels. MIL-SPEC vendors meet U.S. military specifications.
